Vliv drenážního odvodnění na jakost vody
 Svobodová, Natálie
The thesis deals with the issue of drainage of agricultural soils and its effect on water quality. The aim was to describe the basic concepts associated with drainage systems, especially with controlled drainage, and specifications of the quantities measured in the field. Data obtained from monitoring of drainage water quality at the controlled drainage site in Uherčice has been evaluated. Based on this data the effect of regulated drainage and drainage without regulation on the quality of drainage water was compared. The results indicate that conductivity is most influenced by the nitrogen content in the water. Although the concentrations of substances are largely higher in regulated drainage, their proper controlled drainage can encourage the retention of substances in the area, while reducing the removal of substances by the drainage system from the area.
