Hydrology

Hydrology studies the principles of water movements over the Earth. The main aim of the hydrological research is to define an occurrence of water, its circulation, spatial distribution, physical and chemical properties, and it relation to biosphere. As the water is present in all spheres of natural environment, hydrology is closely interrelated with meteorology, climatology, pedology, geology, and ecology. Water abundance, shortage, and pollution represent limiting factors for human development in various regions all over the world. Hence, the hydrological forecasting (both floods and drought) and water quality monitoring are of high importance for the human society.

The Hydrology group at the Institute of Hydrodynamics is focused primarily on hydrological monitoring and on modelling of hydrological processes. Hydrological monitoring takes place in headwater areas in the Bohemian Forest and recently also in agricultural basins in Central Bohemia. The monitoring primarily serves as a fundamental source of data and knowledge about hydrological processes. The data then constitute a base for a development of hydrological models and for a verification of scientific theories. Recently the attention is paid primarily to the effect and importance of soil moisture.
