Department of surface water hydrology (Dr. Yvetta Velísková)

• assessment of the development in trends and prognosis of the groundwater regime changes in the large regions; 

• assessment of the groundwater and surface stream water regime vulnerability with regard at anthropogenic influences in the region scale; 

• evaluation of the large water constructions impacts on the groundwater regime;

• creation and application of a physically-based numerical models for solving of water flow in some specific areas; 

• creation and application of transport numerical models for simulation of non-conservative spreading of biological and chemical contaminants in surface water and groundwater

• creation of multidimensional mathematical and numerical models for groundwater flow for simulation of interaction with surface water, eventually interaction with hydraulic structures.

• the basic hydrological processes in the basin scale;

• the formation and interaction of the basic water balance elements;

• study of spatial and regime characteristics of the hydrological cycle elements in the basin, as runoff characteristics including extreme discharges;

• areal distribution of precipitation and eva-potranspiration (including its components) in the basin;

• quantification of the soil water content;

• the study of the hydrological processes in the natural environment with regard to anthropogenic influences and global change;

Results of these projects are being presented within the international collaboration, mainly within the International Hydrological Progra-mme (IHP) of UNESCO projects 1.1 FRIENDS and ERB project (European Reference Basins). The department members were organisers or co-organisers of the international conferences as Hydrology of Mountainous Areas 1988 Štrbské Pleso, Developments in Hydrology of Mountainous Areas 1994 Stará Lesná, Ecohy-drology of High Mountain Areas 1996 Káth-mandú and Ecohydrological Processes in Small Basins 1996 Strasbourg.

Research objective is the improvement of water balance computations in mountain catchments. The base was established in 1986. Field research is performed in the Jalovecký creek catchment situated in the Western Tatra Mountains (catchment area 22.2 km2, mean elevation 1500 m a.s.l., see picture). The research was devoted to areal variability of precipitation, measurement of transpiration and computations of evapotran-spiration, distribut-ion of snow cover and soil moisture, and runoff generation. Basic network provides precipi-tation, runoff and air temperature data. Water balance computations in monthly time step are carried out since hydrologic year of 1989. At present, the base has 5 employees.

• study of water transport processes in the unsaturated porous media, and development of generalized laws governing these processes;
• methods of determination of the physical characteristics of soils and other porous media, in laboratory and field conditions;
• study of laws governing the processes of water and matter in non - homogeneous soils and in soils with a multi - modal porosity (soil matrix, macropores of various sorts);
• monitoring and measurement of charac-teristics of the water, matter, and energy transport processes, and their modelling;
• mathematical modelling of the water, matter, and energy transport processes in the soil-plant-atmosphere system (SPAC), with the aim of diagnostics and predicting of regimes of the water, matter, and energy in the SPAC system;
• methods of measurement and calculation of the quantitative transport characteristics of the water, matter, and energy in the SPAC system;
• soil water balance in relation to the SPAC system character, and to the anthropogenic activities, oriented to the land with an intensive agriculture;
• influence of long - term changes of the SPAC system character upon the water in soil and in larger hydrological units, and upon consequencies of these changes in water management and agriculture (global climate changes, changes in the land utilization, changes evoked by pedogenesis). 
• hydrology of terrain microdepressions and depression areas,
• influence of anthropogenic activities on water regime of lowland territories,
• water regime of the agricultural areas and the possibilities of its regulation,
• water balance of the lowland areas, its temporal and spatial variability,
• quantitative assessment of the surface and ground water and their monitoring.
