Zhodnocení dlouhodobého vývoje chemismu vody Stropnice v úseku Údolí u Nových Hradů - Petříkov
Čeřovská, Kateřina ; Pokorný, Jan
Evaluation of long term development of chemical parameters of Stropnice river. In: Pithart,D.: Ecology of alluvial oxbows Natural floodplain (c. 800 ha) of Stropnice river near town Nové Hrady was drained and converted into agricultural land in 1980s. The natural meandring stream was straightened and deepened about 2m under the soil surface level. A high profile of flood plain soil was exposed to mineralisation and water flow from the region was accelerated. Data on water chemistry and flow rates collected before and after the drainage were evaluated. Alkalinity, conductivity, concentrations of base cations have increased after drainage which supports hypothesis that drainage accelerates matter losses from the landscape.
