EUROFRIEND - Režim odtoku z medzinárodných experimentálnych a sieťových údajov
Program: UNESCO
Project leader: RNDr. Miklánek Pavol CSc.
Annotation:The FRIEND programme is an international research programme that helps to set up regional networks for analyzing hydrological data. It aims to develop better understanding of hydrological variability and similarity across time and space, through the mutual exchange of data, knowledge and techniques at the regional level. The advanced knowledge of hydrological processes and flow regimes gained through FRIEND helps to improve methods applicable in water resources planning and management. FRIEND is a cross-cutting programme that interacts with all five core IHP-VII themes. A generic overarching scientific objective has been to improve the understanding of the similarity and hydrological variability across different regions of the world, and to share models and techniques between countries, organizations and researchers. The current research covers a diverse range of topics including low flows, floods, variability of regimes, rainfall/runoff modelling, processes of stream flow generation, sediment transport, snow and glacier melt, climate change and variability and its uncertainties, and land-use impacts.

ERB - European Network of Experimental and Representative Basins - ERB
Európska sieť experimentálnych a reprezentatívnych povodí
Program: UNESCO
Project leader: RNDr. Holko Ladislav PhD.
Annotation:The Euromediterranean Network of Experimental and Representative Basins (ERB) is an open association of 20 European countries operating and managing well instrumented experimental and representative basins for hydrological and environmental research on a long term basis. The ERB network promotes the exchange of basin information and the cooperation in international programs as FRIEND, HELP and PUB. Information is disseminated through Newsletters. The Steering Committee of ERB consists of National Correspondents nominated by the UNESCO-IHP National Committees. ERB was established in 1986 and has organised twelve biennial conferences since its beginning. The main objectives are : • To increase relationships between members, research teams, universities and basin managers, through exchanges of hydrological information, data, research methods, models and to organise visits and biennial conferences; • To enable joint studies of common interest • To make available and exchange data between research groups. • To harmonize methods of data collection and processing. Scientific topics and conferences: Despite the large diversity of hydrological problems in our countries there appears always a convergence of hydrological topics of common interest in small basin research to formulate themes of our conferences to which scientists of all member countries can contribute. Examples are: hydrological monitoring, runoff generation, hydrological and environmental modelling, biogeochemical processes, extremes, uncertainties in data and model concepts, effects of natural and man-made changes, erosion, sedimentation, hillslope processes, etc. The organizing country may also select topics of more national or regional interest. The biennial conferences are very important occasions to present and discuss research and to exchange experiences. Especially young scientists can benefit from these meetings by presenting their (PhD) research, discussing their ideas and exchange data to test their hypotheses and model concepts.

IMPACT - Vplyv globálnej klimatickej zmeny na vodné zdroje na Ukrajine odhadnutej pomocou zmien prietoku v riekach a zložkami odtoku
Impacts of global climate changes on water resources in Ukraine estimated by variability of river discharges and hydrograph components
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Pekárová Pavla DrSc.
Annotation:Surface water is a dominant resource for water supply in Ukraine. 85% of water supply comes from the rivers and water reservoirs. Global climate changes resulted in an increase of air temperature in the country. The biggest change is observed in the cold period. In certain years, the average temperature of the cold period is above zero. Although the mean annual precipitation did not change, a decrease in the winter period and an increase in the autumn are observed. Changed air temperature and precipitation patterns result in the decrease of river discharge during spring maxima and its increase during previously low flow periods. Changes in water chemistry were observed as well. Uneven distribution of water resources over Ukraine is combined with shortage of water in regions which are most populated and economically most important. Bad water infrastructure, insufficient water treatment, formerly intensive agriculture and climate change can further deteriorate poor river water quality. The project will consist of two workpackages. In the first one, the analysis of river discharges from selected rivers in Ukraine will be conducted. The results will contribute to better understanding of the variability of river discharges. Second package will focus on hydrographs components. Better understanding of hydrograph components could help explain observed changes in water chemistry and estimate its further development under changed climate.

Analysis of changes in surface water balance and harmonization of design discharge calculations for estimation of flood and drought risks in the Carpathian region
Analýza zmien vodnej bilancie povrchových vôd a harmonizácia výpočtu návrhových prietokov pri odhade rizika povodní a sucha v karpatskej oblasti
Program: VEGA
Project leader: Ing. Bačová Mitková Veronika PhD.
Annotation:Climate change brings a number of uncertainties into forecasting of the future surface water balance. The project is aimed, in the first part, at investigation, analysis and evaluation of changes in hydrological regime at selected streams in the Carpathian region. The years of trend changes, variability, probability and time parameters of their occurrence will be identified. These indicators will be given into the context with the climatological indicators. The EU Directive 2007/60/EC of 23rd. October 2007 requires Member States of EU to draw up flood risk maps for floods with very long return periods. The relationship between peak of the flood waves and their probability of occurrence is one of the fundamental problems of hydrological extremes that have the great importance for water management plans and flood protection plans designing. Therefore the project will also focus on harmonization of the calculation of discharge design values subsequently used to estimate flood and drought risks in a given region.

BIOSOIL - Elimination of degradation processes in soil by biodiversity restoring
Eliminovanie degradačných procesov v pôde obnovením biodiverzity
Program: APVV
Project leader: Ing. Lichner Ľubomír DrSc.
Annotation:The purposes of the project "Elimination of degradation processes in soil by soil biodiversity restoration" are focused on the detection and evaluation of the degree of susceptibility to soil to degradation processes, with a particular focus on susceptibility to erosion and compaction which belong to the most important degradation processes significantly decreasing soil fertility in the countries of European Union and threatening the stability of all components of the environment. The emphasis is placed on sustainable use of land and shall take account of the interaction between soil and water because it is necessary to manage these natural resources carefully and as much as possible to prevent their contamination. The project will use and elaborate innovative methods for assessing the soil properties that have to be adapted to the conditions in soils of Slovakia. Results and assessment will be presented and consulted at international level. Outputs from the project will benefit both: basic research (elaboration of innovative methods and evaluation procedures) as well as the practical application of the methodology by focusing on good agricultural practice for the economical use of land and water, thereby increasing the resistance of soils to degradation effects. This will also contribute significantly to the sustainable use of land.

Strengthening Agroecosystem Resilience: Hydropedological and Biohydrological Aspects
Hydropedologické a biohydrologické aspekty zvyšovania reziliencie agroekosystémov
Program: VEGA
Project leader: Ing. Vitková Justína PhD.
Annotation:Several strategic research and development priorities of the EU identified for 2018-2020 is oriented towards nature-based, low carbon solutions aimed to protect and enhance biodiversity and increase resilience of agro-ecosystems and vulnerable areas against the impacts of the global climate change. Biochar is a manmade substance, an organic matter that is transformed into a charcoal by a biofuel production method called pyrolysis. Especially in the regions of Slovak Republic, the biomass potential for energy production is highly promising. The proposed project is aimed to evaluation the biochar potential in resilience strengthening strategies focused on ecosystems dependent on soil moisture availability. Contrary to the technological approach we would like to analyze the potential of the vegetation itself in its primary and secondary succession stage.

Localisation of accidental point sources of pollution in watercourses based on-line monitoring data
Lokalizácia bodových zdrojov havarijného znečistenia vodných tokov na základe údajov z on-line monitoringu
Program: VEGA
Project leader: Ing. Velísková Yvetta PhD.
Annotation:The aim of the proposed research project is the enlargement of the knowledge and practical contribution to solving a pollution source localization based on the time course of the pollutant concentration in the monitored profile of the river. The prevailing majority of existing simulation models is able to simulate the pollution spreading in the river flow direction only. In current advancing monitoring technologies a task can occur in which the monitored pollution time courses in the cross-flow profile are known, but the pollution source itself is unknown. The goal of such task is simply determination – source localisation (inverse problem). A practical solution of the defined inverse task may be helpful in solving similar tasks in water management practice in identifying sources of accidental pollution. The project also envisages the development of theoretical as well as practical procedures (incl. SW) for solving the above defined inverse problem.

Variability of the water balance and hydrological processes in a mountain catchment under the global change conditions
Variabilita prvkov hydrologickej bilancie a hydrologických procesov v horskom povodí v podmienkach globálnej zmeny
Program: VEGA
Project leader: RNDr. Holko Ladislav PhD.
Annotation:Mountain areas are very sensitive to climate change. Slovakia is a mountainous country, but it has just one small mountain catchment with the long-term measurements of not only precipitation and runoff, but also snow water equivalent and selected hydrological processes. The project wants to answer the questions if and what has changed in the hydrological cycle of the small mountain catchment of the Jalovecký Creek (The Western Tatra Mountains) in hydrological years 1989 to 2018 and if the changes predicted almost 20 years ago correspond to measured reality. Except measured data it will utilize modelling of the soil water flow, distributed hydrological modelling, and stable isotopes of oxygen and hydrogen in water which are monitored since 1991. The monitoring in the catchment will continue to provide data covering the climatic standard period 1991-2020.

Soil water repellency as an indicator of soil drought
Vodoodpudivosť pôdy ako indikátor pôdneho sucha
Program: VEGA
Project leader: Ing. Šurda Peter PhD.
Annotation:Soil water repellency (SWR) or hydrophobicity contributes to many environmental problems, including for example, flooding, accelerated soil erosion, nutrient leaching, pollution of water ways, and reduced groundwater recharge. SWR is caused by organic compounds derived from living or decomposing plants or microorganisms. The probability of occurrence of SWR tends to increase in dry periods and decreases or completely disappears during extended wet periods, i.e., it can be a function of proneness to drought. The aim of our study is to estimate the relationships between the persistence, severity and index of SWR and the drought-proneness factor (meteorological drought index), which determine the severity of the climatic drought. Except for meteorological drought we will evaluate also corresponding minimal soil moisture values. We will analyze experimental localities, which will represent different soil types and different types of vegetation.

Influence of soil texture on water regime in unsaturated soil profile
Vplyv textúry pôdy na vodný režim v nenasýtenej zóne pôdneho prostredia
Program: VEGA
Project leader: Ing. Gomboš Milan CSc.
Annotation:Unsaturated soil zone is a triple-phase system in lithosphere, limited by soil surface and groundwater level. From systemic point of view, unsaturated soil zone is one of the sub-systems forming the system Atmosphere(A)–Plant cover(PC)–Unsaturated soil zone(UZ)–Groundwater(GW). UZ interacts with the other subsystems within the system A–PC–UZ–GW. The intensity of soil interaction processes depends on hydrophysical and hydraulic properties of soil, which are greatly defined by soil texture. Interactions cause temporal and spatial changes in unsaturated soil water regime elements. These changes form unsaturated soil water regime and can be observed in the change of soil water storage. The aim of the project is to quantify the influence of soil texture on unsaturated soil water regime. The project shall quantify the development of unsaturated soil interactions with the surrounding sub-systems of the system A–PC–UZ–GW. Newly constructed state-of-art technology will be used for the purposes of the project.

Influence of aquatic vegetations on quantitative and qualitative parameters of lowland streams
Vplyv vodnej vegetácie na kvantitatívne a kvalitatívne parametre nížinných vodných tokov
Program: VEGA
Project leader: Mgr. Schügerl Radoslav PhD.
Annotation:Occurence of aquatic vegetation is very frequent problem of surface water streams, primarily in lowland areas. Possibility of plant growth is mainly during a summer period. Aquatic vegetation reduces discharge and deforms velocity profile. Moreover, surroundings of lowland water streams is commonly agricultural with frequent fertilizer utilization. Result of that is the increasing of nutrient concentrations in water, which lead to plant growth extension. The aim of the project will be the quantification of water plants influence on discharge and flow conditions. The next aim will be an analysis and quantification of nutrient content impact and impact of water temperature on degree of stream sprouting. For achievement the goals there will be utilised the latest equipments and methodical procedures along with verified statistical analysis methods.
