  • Title: Flow Regimes from International Experimental and Network Data
    Duration: 1.1.2014 – 31.12.2021
    Co-ordinator: Pavol Miklánek (national coordinator)
    Abstract: 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.

  • Title: European Network of Experimental and Representative Basins - ERB
    Duration: 1.1.2013 - 31.12.2021
    Co-ordinator: Ladislav Holko (national coordinator)
    Abstract:  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.

  • Title: The system of porous media parameters evaluation by EIS  method in wide spectrum of application;
    Duration: 1.11.2012 – 31.12.2017
    Co-ordinator: Branislav Kandra (national coordinator)
    Abstract: Development and realization of monitoring system based on the method of electrical impedance spectrometry for monitoring selected parameters of porous organic and inorganic substances for application in conditions of real environment, agriculture and of food industry is solved in project.

  • Title: DanubeFlood - Flood regime of rivers in the Danube river basin

    Co-ordinator: Pavla Pekárová (coordinator)
    Abstract: The territory of the Danube River Basin is one the most flood-endangered regions in Europe. Therefore there is a strong need to have complete and exhausting information on the flood regime in order to be able to generalize such information on the basis of long-term observations from the whole Danube territory. Flood data from more than 50 stations will be processed to analyse the mean daily discharge rates variability (and annual peaks Qmax as well), from the period 1901–2005 (1876–2006, and more). Further, possible relationships between the annual discharge characteristics of the Danube River and the world climate phenomena (NAO, AO, QBO) will be examined. This information can be used for water management and design of flood control structures and for improvement of the methodological base of institutions and agencies responsible for flood warnings.

APVV bilateral projects

  • Title: Influence of biophysical and environmental factors on deviations between measured and calculated evapotranspiration
    Duration: 1.1.2016 – 31.12.2017
    Co-ordinator: Marek Rodný (SK-AT)
    Abstract: Evapotranspiration (ET) represents the most important component of the water cycle. Proper ET estimates are essential for precise evaluation of energy and water balance studies. Several studies already documented deviations between measured and calculated evapotranspiration depending on environmental and weather conditions. The aim of this project is to assesses biophysical and environmental factors of influence on deviations between measured and calculated evapotranspiration losses and subsequently plant water requirements. Moreover, strong transfer of skills and knowledge on maintenance and operation of the lysimeter facilities, monitoring systems and evapotranspiration models is expected outcome of the international research cooperation.
  • Title: Effect of biochar and dairy sewage sludge application on hydrophysical and mechanical properties of agricultural soils
    Duration: 2016–2017
    Co-ordinator: Peter Šurda (SK-PL)
    Abstract: Recently, there has been much scientific interest in the different soil amendments as application of biochar, a carbon-rich solid material, or diary sewage sludge, mainly due to its potential promising characteristics in relation to soil conditioning. However, conclusive evidence on alteration of soil properties, processes and functions was not completed yet. Following research project will evaluate in laboratory conditions the extent and implications of biochar and diary sewage sludge application on selected soil physical characteristics, which determine hydrophysical and mechanical characteristics of agricultural soil.

  • Title: Evaluation of surface soil moisture from satellite and ground-based measurements
    Duration: 2016–2018
    Co-ordinator: Justína Vitková (SK-PL) 
    Abstract: Soil moisture together with soil and vegetation characteristics, plays an important role in exchange of water and energy between the land surface and the atmospheric boundary layer. Accurate knowledge of current and future spatial and temporal variation in soil moisture is not well known, nor easy to measure or predict. Knowledge of soil moisture in surface and root zone is critical for achieving sustainable land and water management. Research concern the proofs of the climate change issues related to evaluation of water storage in soil from ground and SMOS (Soil Moisture Ocean Salinity) satellite measurements, in area of 3 Transboundary Biosphere Reserves situated both in Poland and Slovakia. Studies conducted in the years 2013-2015, we want to continue for another period 2016-2018. The focus is on validating soil moisture, and classifying the vegetation cover towards the water content bound to the canopy. In order to improve our understanding of how the management and land use modify the water and thermal processes the use of modelling is required. In this research project we plan to use SMOS and ground data for prediction of topsoil water distribution in Poland and Slovak territory.
