- Hydrology of watercourses and changes of water balance structure of water basins,
- Movement of water and soluted stuff in the Groundwater-Soil-Plant-Atmosphere System and its quantification,
- Quantification of the surface and subsurface water and soluted and dispersed stuff movement,
- The influence of anthropogenic factors on hydrological processes and on pollution of surface water and groundwater,
- Identification and prognosis of surface and subsurface water regime by expected climate changes.
Different subdisciplines of hydrology are using specific methodological approaches and equipments, this is reflected even in structure of the Institute. Institute is divided into two departments:
Territory of Slovakia is morphologically diversified and research under different natural conditions needs specific methodology and equipment; the remoted workplaces for particular regions were established; they are focused
on research in the field conditions:
- Experimental Hydrological Base, Liptovský Mikuláš, (research of water movement and runoff formation
in condition of mountainous catchments),
- Hydrological Research Base, Michalovce (soil hydrology of lowlands, with accent to East Slovakia Lowland).
The aim of research conducted by the Institute of Hydrology, Slovak Academy of Sciences is to acquire new knowledge about quantitative and qualitative characteristics of water movement in ecosystems influenced by human activity and global changes (climate change is one of many global changes).
Those goals can be reached by the combined laboratory and field activities; field research is the source of primary information about the system and allows to design mathematical models and its results can be used for their validation. Mathematical models, designed at the Institute of Hydrology are valuable tools to diagnose and prognose water regime of surface and subsurface water.
Results of research are disseminated by journals published by the Institute of Hydrology SAS (Journal of Hydrology and Hydromechanics – jointly with the Institute for Hydrodynamics AS CR, and Acta Hydrologica Slovaca), in foreign journals, monographies and are presented at the conferences.
Increasing demand on water supply, higher level of prevention to floods and droughts needs new knowledge about water cycle, to be able – together with another institutions in this field – cover increasing water need and prevention to extreme hydrological phenomena.
