EUROFRIEND - EUROFRIEND - Flow Regimes from International Experimental and Network Data
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.

WATSIM - Water temperature simulation during the low flow conditions in the Danube basin
Simulácia teploty vody v tokoch v povodí rieky Dunaj počas nízkych prietokov
Program: UNESCO
Project leader: RNDr. Pekárová Pavla DrSc.
Annotation:The proposed project is oriented on long-term variability and long-term trends of water temperature of selected rivers in different regions of Danube basin (high mountains, highlands, lowlands) and along the Danube River. Multiple regression technique will be used for analysis of relations between water temperature and influencing factors (low and high discharge conditions, increasing atmospheric temperature, anthropogenic activity in basin, etc.). The multiregresion simulation and stochastic forecasting models (Box Jenkins models, ARIMA, SARIMA) of water temperature will be developed for selected rivers. These models will be used for simulation of the water temperature of selected rivers according to different discharge, and air temperature scenarios. One of the expected results is the scientific base for method of water quality classification according the water temperature of water bodies in Danube basin for implementation of WFD 2000/60/EC. The results of the project will be summarized in common monograph of the project team.

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.

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.

KVANPROC - Quantification of Interaction Processes in Hydrological Cycle in Lowland area conditions
Kvantifikácia interakčných procesov v hydrologickom cykle v podmienkach nížinného územia
Program: VEGA
Project leader: Ing. Gomboš Milan CSc.
Annotation:From a systemic point of view, the hydrological cycle is understood as a rugged unit composed of several parts between which there are bonds. This system consists of an open physical system that can be divided into atmosphere (A) - plant cover (PC) - unsaturated zone (UZ) - groundwater (GW). Interaction processes take place between individual subsystems. The size and intensity of interactions depend on the geographic, geophysical and climatic conditions of the area. The fundamental importance of knowledge of the interaction processes is, above all, that transport of mass, energy and biomass are realized there. It is a fundamental basis for adaptation arrangements. The aim of the project is to quantify interaction processes in various time scales. Temporal development and mutual links along the vertical of the systém will be examined. The research will be carried out in the environment of the East Slovak Lowland (ESL). Lysimetric research, numerical simulation and monitoring methods will be applied.

Regionalizácia povodňových špecifických odtokov s dlhou dobou opakovania na Slovensku
Program: Iné projekty
Project leader: RNDr. Mészáros Jakub
Annotation:Despite the significant development of statistical methods for determining the parameters of theoretical distribution functions, the identification of flood-specific runoffs remains a complex problem, burdened by various uncertainties. The floods that have affected not only our territory in recent decades have led to the adoption of the EU Floods Directive, which requires estimation of floods with a very long repetition period (200 to 1000 years). Now, at the time when climate change is actual, the weather has more extreme effects. Thus, the precipitation from which the runoff is formed is more intensive and unevenly distributed. That is the reason why is necessary to know precipitation patterns and determine where and how great flood could be caused.

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.

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.
