Laminated glass is a commonly used building material. Owing to a combination of glass layers with transparent polymer interlayers, this material is aesthetic and meets high safety standards. If well designed, interlayers can dissipate part of the impact energy, hold the glass fragments together, andshow more prevent penetration of pressure waves and bodies through building envelopes. However, improving designs calls for a reliable description of the glass behavior. To this end, we aim to numerically and experimentally analyze the effect of the blast and ballistic impact, their successive or combined actions, on multilayer laminated glass, thereby deepening the current knowledge. The overarching objective is to implement, validate, and verify a phase-field damage model and investigate its suitability to predict the post-breakage behavior of the laminated glass under blast loads. Complementary to this, we will develop an innovative experimental methodology for laminated glass subjected to blast with a simple interpretation of results that allows for a reliable validation of numerical models.

Annotation

Cement production is one of the largest sources of CO2 emissions. One way to decrease these emissions is to reduce cement consumption through the wider use of blended cements from local sources of pozzolanic active ingredients. Although this is a technologically simple solution to this urgentshow more problem, most blended cements have low initial strength, which is, in practice, not competitive with traditional composites with higher cement content. In order to improve their strength, it is necessary to understand the chemical processes taking place in the early stages of cement hydration. While most studies focus on the main clinker mineral C3S, there is only a limited amount of information about C3A, the most reactive clinker component. Understanding the influence of C3A on the initial strength of cement and the early hydration of cement from a micro-and macroscopic point of view are the main goals of this project. The achieved results could help with the design and optimization of the initial properties of blended cements, which are expected to be more widely used in the near future.

These alternative precursors will be used after thermal activation, but the possibility to prepare ABG from thermally untreated clay be examined as well. The prepared ABG will be characterized among other techniques by solid state MAS NMR spectroscopy, which will provide unique information about their structure and synthesis mechanism. The structural data will be correlated with mechanical properties.

The sufficient durability of solid wood and wood products is important for its use in building components. Mould growth on wood is often a precursor of further decay. Since mould growth is influenced by hygric conditions of a substrate material, a prediction of mould growth may serve as warning thatshow more moisture state of building component is not satisfactory. Mould growth can be understood as the serviceability limit state of a building component. Existing mathematical mould growth models attempt to quantify either the amount of moulds on the surface or the probability of presence of moulds for given environmental conditions and material parameters. Such models are based on regression of laboratory mould growth experiments. There is a lack of reliable good quality experiments. Consequently, there is a lack of systematic comparison between mould growth models and experiments. This project will further develop the newly established logistic mould growth model. The model will be compared with performed experiments. Reference growing media prepared from pine sapwood will be used in mould

Numerical simulations of inelastic mechanical behavior of heterogeneous quasibrittle material are essential in a number of engineering areas. Specifically in civil engineering they are applied in assessment of critical buildings and infrastructure made of concrete. Robust high-fidelity modelsshow more require detailed information about material composition which makes them computationally prohibitive. The projects solves this burden by state of the art techniques using machine learning combined with homogenization and domain decomposition. The heart of the project is advanced physically constrained machine learning surrogate capable to locally replace material response. Such artificial intelligence will be used to emulate behavior of (i) spherical representative volume element in the asymptotic expansion homogenization and (ii) regions tiling the decomposed domain. For such goal the homogenization will be equipped with auxiliary modes accounting for strain localization and the domain decomposition will be improved by reduced order modeling of the communication between individual regions.

Concrete production remains as one of the highest CO2. The most common type of reinforcement used are steel rebars. Due to the additional concrete cover to protect steel from corrosion higher amount of concrete is consumed, the overall cost and environmental impact associated with material provisionshow more. Textile reinforced concrete (TRC) is a silicate composite material in which reinforcement consists of one or multiple mesh structured layers manufactured from inorganic fibres. Due to the use of a noncorrosive reinforcement, additional cover requirements can be limited, reducing the amount of cement and resulting in a higher sustainable potential. Growing research has been directed towards the use of more sustainable alternative materials. Natural fibres are renewable, widespread and accessible to both developing and developed countries, and can be recycled and biodegraded. Moreover, some plant fibres have high specific mechanical properties. Hence natural fibres start to be considered as potential sustainable replacements to steel and synthetic reinforcements for concrete matrices.

The project deals with ductility and strength requirements for eccentrically connected bolted gusset plates under compressive load and for bolted lap connections made of normal and high strength steels (HSS) up to S1000. Although these bearing type connections have been used since the end of theshow more 19th century, there are still many questions concerning their design. A few analytical methods for compressed gusset plates connections were developed and some of them are used in standards procedures, mainly in Australia, New Zealand and Canada. However, in European standards, no design procedure is described. The basic problem of bolted, bearing type, lap connections in HSSs is that it becomes difficult to respect the traditional ductility requirement in terms of providing the bearing resistance not greater than the shear resistance of bolt. This leads to non-uniform distribution of forces between bolts. The project addresses demands for design of connecting plates and bolts in gusset plate and lap connections.

The proposed research is aimed to resolve the influence of fire-induced dynamic actions on structures. Achieving this goal requires acquiring knowledge about the behavior of materials at simultaneous high temperatures and high strain rates. This must be achieved experimentally. In this research, theshow more material of interest is structural steel used in civil engineering. The general conclusion on the state of the art is that steel properties at simultaneous high temperatures and high strain rates are not well-recognized research topics. Experimental results on material behavior allow for calibration of mathematical material models, then implementation into the structural model and finally, the analysis of the structure. t is postulated that steel structures exposed to fire and fire-induced dynamic actions can be successfully analyzed and modeled after gaining knowledge of the underlying physical phenomena related to the simultaneous effects of temperature and high strain rates on mechanical properties.

Multiscale material modelling for additive manufacturing is one of the most promising development fields for future industries. To fully exploit the opportunities of multiscale structures, the topology optimisation of architectured (meta)materials must be accurate and accessible. This projectshow more addresses two of the challenges in designing high-resolution architectured microstructures. First, an expensive computational homogenisation is solved by the fast Fourier transform-accelerated finite element solver, which is improved with the mesh coarsening technique based on low-rank tensor approximations. Second, as the manufacturing resolutions reach micrometre accuracy, surface effects such as adhesive contact are implicitly involved in the micromechanical model to accommodate phenomena associated with the increased surface-to-volume ratio. The project will be conducted in cooperation with leading experts on multiscale modelling and additive manufacturing from the livMatS Cluster of Excellence, Freiburg, Germany, with an emphasis on the knowledge transfer into the Czech environment.

Technical installations are complex systems, the structure of which is currently described by the system engineering as the systems of systems (SoS), i.e. a set of open systems integrated into a larger system that provides unique services. The safety management process must be applied at all stagesshow more of the life of the technical installations, i.e. also during the reconstruction process. The aim of any reconstruction is that the reconstruction process does not cause unacceptable damage and losses, so as not to create new risks and at least to maintain the current level of safety of the work. Therefore, during reconstruction it is necessary to rely on the applicable standards and good engineering practice, but also to monitor and manage priority risks in order to achieve this objective. Based on current knowledge and recommendations of standards, e.g. ISO 31 000, ISO 31 010, ISO 9000, etc., we want to propose a procedure for linking standards and risk management results in the process of reconstruction of critical element (metro station) of critical transport infrastructure. Since the subject norms and standards do not indicate the procedures for how to carry out the link, we will address the problem in question on a practical example, considering both, the process safety and the integral (overall safety). To ensure safety, we will create a tool "Risk management plan for the reconstruction of an element critical Infrastructure".

Combustion products can be defined as solid materials that are formed during the combustion of solid fuels and during the flue gas desulphurisation process in power plants and heating plants. Their use in the Czech Republic is currently largely limited to reclamations in the vicinity of power plantsshow more, most often in the form of agglomerated, deposited or landfill ash, which is a mixture of several combustion products (CCP's), with difficult or impossible separation of individual components. The application of CCP's in advanced products is in many cases hindered by some of their chemical, physical and mechanical parameters, which are given by the way they are created and the production technology during combustion. The integration of existing and stored CCP's in more complex products (especially construction products) is low. The market in the Czech Republic and in Europe is proving to be experiencing a critical shortage of secondary materials for construction production, which has been reflected in rising prices. CCP's have a significant positive effect in the circular economy on reducing the total price of the resulting construction works and products, improving some technical parameters of building materials and significantly reducing the energy intensity of primary raw materials - especially cement and anhydrite and subsequent construction products and structures (concrete, earthworks structures, etc.). A significant side effect is the reduction of CO2 and NOx emissions when replacing primary raw materials, as emissions from the production of combustion by-products are included in the electricity product. Only by replacing 1 ton of cement by fly ash, you can save approx. 0.75 tons of CO2 emissions, simply because all CO2 emissions from the production of fly ash are balanced within the electricity product. The main goal of the project is to verify the possibilities of treatment of fresh and stored CCP's, thanks to which it would be possible to use the output of so

Earth construction is historically one of the most widespread methods of construction ever. In connection with the emphasis on reducing the carbon footprint and the principles of sustainable building, more and more builders around the world are returning to this material and are implementing it inshow more modern buildings. Clay is not only an environmentally friendly material, but also easily available in most locations. One of them is the Zambian region of Kashitu, where the local community is in dire need of building a new high school campus. Working with clay doesn't rely on the use of heavy equipment and is an ideal material for DIY construction. These environmental, economic and social benefits are one of the main reasons why this technology is widely used in developing countries, where members of local communities can participate in the construction process. In Zambia, clay structures have a long tradition. Although clay is one of the oldest building materials, its use in our environment is mainly hindered by the prejudices of the current construction community and the lack of technical standards. The main objective of the proposed research project is to test the properties of clay adobe bricks not only in laboratory conditions, but also during the construction process of the first campus building of the future Zambian high school. The project builds on a several-year tradition of clay construction research carried out at the Department of Building Structures of the Faculty of Civil Engineering at CTU in cooperation with the International Center for World Development (ICWD) and the non-profit organization Friends of New Renato, which is the main initiator of the project. The non-profit organization currently manages a community center and a primary school in the area.

Sensors that measure the temperature of the heated space are a key element for controlling a radiant heating systems. It is known from general thermal comfort theory that the closest temperature that expresses the overall thermal sensation of a person is the operative temperature, or the resultingshow more black-globe thermometer temperature. This temperature includes the radiant temperature of the surrounding surfaces, expressed as the mean radiant temperature, and the air temperature of the heated space. A black-globe thermometer placed in the centre of the heated room is used to determine it. In practice, this solution is very difficult to implement, so the black-globe thermometer in the middle of the room is replaced either by air temperature measurements and correction factors or by sensors that also capture the radiant component of the heat sharing. The subject of this paper are the results of testing a newly developed sensor to replace the black-globe thermometer. The testing will involve the creation of a working sample of the sensor on a 3D printer, a laboratory test and then CFD simulation of the placement of the new sensor in a room with different heating systems - floor, ceiling and radiator heating. For each heating system, the placement of the new sensor in 3 different room positions will be simulated and the values obtained compared with those of a simulated black-globe thermometer placed in the middle of the room. For all simulated situations, boundary conditions will be set for the design state of the heating system and for the state corresponding to the transition period. The building structures that form the room will be specified in accordance with the current regulations for nearly-zero energy buildings. A detailed model of the new sensor, a detailed model of the black-globe thermometer and a model of the test room will be developed in the CFD modelling. The steady state condition at the given boundary conditions was simulated and at the same time v

INVESTIGATION OF A SPATIAL FLOW OVER THE HYDRAULIC STRUCTURES

Investigation of hydraulic structures is particularly necessary when dealing with hydraulically complex water flow and water flow at the boundary of hydraulic phenomena (so-called transient flow). Many hydraulically complex phenomena cannot be described mathematically or using known equations andshow more relationships. The difficulties in parameterising these phenomena can be avoided by physical modelling. By building a physical model and then simulating various load conditions, it is possible to test and verify the proposed design very accurately and to observe the hydraulic phenomena that occur in detail. This is possible by measuring common variables (water depth, flow velocity and direction, hydraulic losses, water pressure, pressure pulsation, etc.). When hydraulically complex flows are investigated, basic hydraulics cannot be used, but physical modelling needs to be combined with mathematical modelling (so-called hybrid modelling). The project aims to elucidate and parameterise the problem of dissipation of kinetic energy of water and the behaviour of aerated water flow when water currents collide, e.g. in an outlet or on stepped spillways. Furthermore, the aim is also to address the influence on the structure of the waterworks - pressure pulsations, level fluctuations, vibrations, etc. These are some of the basic hydraulic questions asked in hydraulics. The approaches to energy dissipation used in the research can be generalized to other hydraulic structures. However, their results are not, as each hydraulic structure is unique and the hydraulic phenomena occurring on it are highly varied. At our department, we have been dealing with the problem of hydraulic research with a combination of mathematical and physical modelling for many years. In this project, we will build on the experience of the past years. Hydrotechnical research will be applied to the following issues: water energy dissipation on the spillways and in the outlet, collision of water currents, aeration

The main objective of the project is to determine the turbine characteristics of the existing microturbines and to propose possible shape modifications (possibly less extensive shape optimization) of the existing runners and hydraulic profiles of the turbines with subsequent analysis of the effectshow more of these modifications on the turbine characteristics (especially efficiency at unit discharge and speed). The project will be based on the use of 3D scans of existing microturbines (especially pumps in turbine mode - PAT), modification of the 3D scans, comparison of the manufacturer's pump characteristics with the observed characteristics by CFD calculations, and generation of turbine characteristics using numerical flow modelling (CFD) methods. Particularly for sites with low turbine power (up to approximately 100 kW), existing microturbines are inappropriately designed, both due to inappropriately shaped hydraulic profile and shape of runner, and due to inappropriate operation on a different head and discharge than the turbine is designed for. PAT units are a typical example of the application, their biggest advantage being their relatively low purchase price (mass produced pumps). Unfortunately, this advantage is very often limited by the low hydraulic efficiency, typically only around 50%. At the same time, an analysis of the applicability of variable speed operation using a frequency converter for selected turbines will be carried out. It should be emphasized that the objective micro-hydro localities is usually not to achieve peak efficiency, but to maximize power generation over a period of time assuming the same hydrological or operating conditions.

Research on climate change is particularly relevant in terms of predicting its impact on hydrological regime and the reliability of water resources, which have a significant impact on water supply. There are countless studies worldwide on climate change and its impacts on the hydrological regime.show more These studies use the outputs of climate models that reflect estimates of the evolution of greenhouse gases in the atmosphere based on predictions of the socio-economic development of society and the production of emissions. Using appropriate hydrological models, the studies quantify the impact of climate change on the hydrological regime. Despite some uncertainties in climate models, this is the preferred approach worldwide. However, hydrological changes are further propagated to the water management sector, making it extremely important to be able to quantify the impacts of climate change on water resources as well. However, the overlap of studies into the water management sector is not frequent. This may be due to the large amount of data, the need of automat computational procedures and the time required. Despite the disadvantages of this approach, this research has great potential for the design of future adaptive measures. The case studies show that there will be a temporal and spatial redistribution of precipitation, an increase in average air temperatures and a decrease in the reliability of water resources. Reservoirs are a very robust and reliable measure in this context. The aim of the project is to assess the vulnerability/resilience of water resources in the pilot locations to the predicted impacts of climate change. The project will include an assessment of reliability of water supply and reservoir storage reliability under predicted climate change conditions, as well as an assessment of the need to update existing dispatch control curves.

Current practice, particularly in the field of green roofs, involves the use of specialized substrate mixtures with precisely designed hydraulic and chemical properties.

A MULTISCALE APPROACH TO UNSATURATED FLOW IN POROUS MEDIA WITH PREISACH HYSTERESIS

Period
1. 4. 2023 - 31. 3. 2025
Annotation

Experimental evidence indicates that filtration through unsaturated porous media exhibits a hysteretic behavior. This phenomenon arises at a microscopic level, and can be explained by the surface tension on the contact between water and air in the pores. As a result, the pressure-saturationshow more constitutive relation turns out to be of hysteresis type, and can be accurately described resorting to the Preisach operator. The main objective of the MulPHys project is to expand the knowledge and build new mathematical models of Preisach hysteresis in unsaturated porous media, employing a multiscale approach. The capability of the Preisach operator to describe the hysteretic behavior of unsaturated porous solids during filtration was proved experimentally employing a thorough fitting procedure. This sparked an intense research effort in the community of experts in PDEs with hysteresis, with the goal of including the Preisach operator in mathematical models. In these works the presence of a microstructure was neglected, being the approach directly macroscopic. On the other hand, a rich literature has looked at porous media as objects with a microstructure, and has derived the macroscopic description of fluid flow from the local behavior. In these papers, however, the porous media is often assumed to be completely saturated, so that no hysteresis can occur. With the present project we will fill the gap between the two research areas, employing homogenization techniques to provide a justification of the Preisach operator as the correct tool to describe filtration. Particular attention will be paid to the problems of including gravity effects in the model and understanding the solid-liquid interaction at the microscopic level. Numerical simulations and laboratory experiments will be instrumental in achieving the objectives. A significant impact is thus expected either on the scientific community, on the professional sectors and, indirectly, on the whole society.

Předkládaný projekt se zabývá architekturním a slavnostním osvětlením exteriéru památkových objektů a urbanistických struktur v historickém kontextu. V posledních letech dochází k rychlému rozvoji osvětlovací techniky. Roste její účinnost, cenová dostupnost, nabízí se mnoho vizuálních efektů,show more které by ještě před deseti lety byly zcela nedostupné. Zatímco v době jejích vzniku byly historické objekty navrhovány pro denní osvětlení a jejich osvětlení po západu slunce bylo technicky nemožné, dnešní trend je opačný a elektrické osvětlování objektů se stává záležitostí obvyklou až nezbytnou. Pro navrhování architekturního osvětlení neexistuje žádné původní příkladné řešení, ani se nelze opřít o žádnou metodikou ani legislativou upřesňující správný návrh světelných parametrů. Současná legislativa stanoví pouze požadavky na osvětlení z hlediska bezpečnosti a orientace v nočním prostředí. Důsledkem je často osvětlení bez ohledu na historický charakter objektu, atmosféru a genius loci blízkého okolí. Zřetelné jsou tendence k nadužívání světla, zbytečné přesvětlování objektů, nevhodné směrování světla či umístění zdrojů způsobující oslnění. Správně nastavené světelné parametry mohou zvýšit estetickou a kulturně historickou kvalitu osvětlovaných objektů, omezit negativní vliv světla na okolí a snížit energetickou náročnost osvětlení. Prostředkem k vytvoření kvalitního světelného prostředí je především nalezení přiměřeného jasu na fasádách objektů, vhodně zvolené spektrální složení a směrování světla v prostoru. Zřetel by měl být brán také na dodržování noční doby i s ohledem na potřeby přírodních společenstev i člověka.

The immovable industrial heritage, cultural heritage and national identity, has still been on the periphery of the interest of a part of the professional and lay public. Quantity of buildings is endangered and only an insignificant percentage of them is protected. An appropriate form of preservationshow more, in which the majority of the defined values of a building is protected so that the building to be able to be further actively used for new, most often non-manufacturing functions, is the current issue. Since the 1970s these methods of adaptation have been proven abroad and with some delay also in our country by many realizations. The specific examples and approaches to reuse prove that in the complex process of the rescue of the industrial heritage there is a lack of understanding of the relationship between the original characteristics of manufacturing and the new function. The project perceives as the main criteria the adaptability of the building and its compatibility with the new function, characteristics often ignored in the evaluation of the quality of industrial buildings and the design of their new use leading to misunderstandings between the sides concerned about the meaning and possibilities of the new use. The aim of the project is to identify and define the features of the industrial heritage objects that facilitate their new use and ensure their active protection and effective next use. The relation between the original building substance and the new use will be investigated on 2 levels. 1. assessment of the characteristics of each typological type of industrial buildings 2. description of the new potential function The theoretical part will be supported by examples of current realizations and projects from Czechia and abroad. An analysis of general group features will be made as well of the methodically sorted out possibilities of sustainable use - preserving cultural values and the necessary degree of authenticity of the building and the environment.

It is a spatial phenomenon, influenced by many aspects, mainly territorial-administrative, power and ideological, ethnic, religious, cultural or mental. Newshow more boundaries continuously emerge, change, disappear and interpenetrate in layers. Understanding the subject of borders in terms of their identification, i.e. their temporal, horizontal and vertical layers is very difficult for the public and many experts, both domestic and foreign. The main aim of the present project is to create a concept of the basic groups of borders and border changes in the Czech lands with a link to the Central European space from the Middle Ages to the end of the 20th century; to process the basic files of individual types of borders; to analyse, compare and interpret the obtained data; to make the research results available to the general and professional public, and thus to present, as far as possible, a comprehensive picture of borders and their changes. This objective is in line with specific objective 1.1 National and cultural identity in history and archaeology. The proposed project will be carried out in three phases within five thematic modules: I. Boundaries, their typology, symbolism and ways of expression in extant sources; II. Borders as a reflection of territorial governance, power ambitions and conflicts; III. Borders as a reflection of ethnic, linguistic and cultural anthropological phenomena and processes; IV. Borders as a reflection of historical specificities and anomalies; V. Borders as a reflection of the diversity of opinions in contemporary society.

Changes in the landscape and its use, and the changes in human activities that are related to these changes, are very fundamental to understanding the historic landscape around the river. We are building on the previous NAKI II project, which revealed a large number of additional themes that were previously unaddressed. In particular, the project addresses the transport function of the river, both in terms of transport links (transport of people and raw materials) and barriers (the need for fords, ferries, bridges). Both the link and the barrier feature have greatly influenced human activities and the exploitation of the cultural landscape, which we want to document in the project. The project also addresses the subsidiary Thematic Priorities 4. National and Cultural Identity in the Memory Culture of the Nation and 16. Methods of Identification, Documentation, Evidence and Interpretation of National Immovable and Movable Cultural Heritage.

The processing of the partial information obtained in this way, and especially its interpretation, will provide new information and insights into changes in the historical landscape and its use. The main goal of the project is to process a large amount of archival materials (documents, maps, plans, photographs) and to build on the existing results of the previous project by combining and digitizing them.

In the twenty-first century, we have entered the era of soft materials. Soft materials are omnipresent in nature as well as in emerging fields such as flexible electronics and soft robotics. Interestingly, surface stress can dominate the behavior of soft solids. Many works consider constant andshow more isotropic surface stress in the response of soft material surfaces. However, it has been recently experimentally proven that the behavior of soft surfaces is strain-dependent. The strain dependence of the surface energy brings exciting opportunities as well as challenges. The main goal of SOFFA is to advance the field of soft materials with strain-dependent surface energies. The ground-breaking nature of this proposal lies in the development of (1) a novel, mathematically well founded approach for the description of a strain-dependent surface. Moreover, models with curvature-dependent surface energy, usually neglected for soft solids, are also developed and studied. The second primary objective addresses (2) the modeling of surface instabilities in soft materials with surface energies to open new possibilities for the design of soft materials and devices at small scales by avoiding catastrophic failures and exploiting instabilities to control phenomena such as crack propagation and adhesion. Finally, the developed constitutive models and methods for instability tracking will be integrated into (3) a unique, robust, and scalable opensource simulation tool. The tool will be used to study the effect of strain-dependent surface energy on crack propagation, switchable adhesion, and tunable macroscopic behavior of matrix-inclusion composites with interface stresses.

The knowledge on the behaviour and modelling of contactors will focus newshow more materials that have the potential to reduce emissions and energy consumption, high strength steel. This will increase the competitiveness of steel structures and enable innovative applications driven by the European Green Deal action plan on the circular economy. In order to design safe, reliable and efficient structures, a thorough knowledge of their behaviour is required. This knowledge is contained in the standards for structural design. Traditionally, standards have used analytical procedures that can be easily applied in hand calculations. This brings undeniable advantages, but these procedures are simplistic and do not allow for the complex cases that are needed for the design of contemporary load-bearing structures in advanced materials. Advanced computer simulation modelling, using the finite element method, is a new discipline for structural steel liaison engineers and is being adopted in practice because of its accuracy and general applicability. Advanced modelling for engineers greatly expands the scope of application by directly simulating the behaviour of the structure. This approach achieves accurate results for a wide range of cases. However, differences have been identified on the hazardous side for connections where failure by breaking is critical, especially for high strength steels where the difference between yield and ultimate strength is small. Breakage is now simulated by reaching the plastic yield strength. This depends on the physical properties and geometry and on modelling properties such as finite element type or mesh density. The optimal combination of the plastic remoulding limit and modelling properties is unknown. For structures made of conventio

The impacts of climate change in Austria and Czechia are manifold. Climatic areas of the agricultural production, crops, agrotechnology as well as problems in the landscape we are currently facing are close to each other in both countries. In the field of ecosystem services of landscapes, theshow more problem of Austria's water resources and the closely related area of food production should be addressed. For example, the BEAT study by AGES and its partners (Haslmayr et al., 2018) has shown that under the conditions of climate change, massive declines in yields must be expected in the coming decades, especially in the eastern region of Austria. This is due to higher annual temperatures, increased evaporation and thus lower water availability. An additional burden is the pluvial floods that have been occurring more frequently for several years, causing enormous damage to infrastructure in settlement areas by sediment transport. Consequently, sediment transport may be seen as a valuable proxy for large-scale water and nutrient cycling. The progressing experiences of the Czech-Austrian project team in ecohydrological modelling will be exchanged in this bilateral project and the different scales of the three study regions (HOAL, 60 ha; Retzer Land, catchment parts between around 0.5 and several 100 ha; Vrchlice, 10 000 ha) will allow the progressing of up- and downscaling approaches for feasible result interpretation.
