Development of water quality in the river basin is determined inter alia by the spectrum and the progress of anthropogenic activities. Their reducing or development is immediately reflected in a change in water quality.
The method and intensity of agricultural land management, livestock farming, concentration of industry and settlement development are related to the demographic, socio-economic and political development of society. In the Czech Republic there has been a significant change in water quality in the 20th century.
In the Czech Elbe River basin has tackled this issue Langhammer. While at the beginning of the 20th century the quality of the water in the Elbe enabled its versatile use, it was radically deteriorated in the second half of the century.
Only after the political and economic changes commenced in 1989 the water quality in the Elbe River had improved again, but not in all parts of catchment area. One of the river basins, where the quality of water is still very low, is the catchment area of the Šlapanka River, the left-side tributary of the Sázava River.
The aim of the study was to find out what developments occurred in the surface water quality in basin in 2002 and 2014.
