Development of surface water quality in selected rural areas of the Elbe River basin Water quality is an enduring issue in water management and has global importance. This work deals with surface water quality in the Elbe River basin, focusing on river basins in agricultural and rural areas where surface water quality remains a significant ecological problem. As part of this work, two watersheds with a significant representation of agriculturally used areas were chosen: the Mastník River catchment, which flows into the Vltava River, and the Šlapanka River catchment, which flows into the Sázava River. In the case of the Mastník stream, the work deals with the basin itself and changes in water quality in the Mastník bay, which is part of the Slapy reservoir located on the Vltava River. Water quality was analysed using the concentration of selected parameters through long-term field research supplemented with data from the State Enterprise of the Vltava River basin. In this part, it was proved that constructing new wastewater treatment plants (WWTPs) gradually improves the overall water quality. However, the parameter chlorophyll-α and the lack of dissolved oxygen remain problematic. The finding of high concentrations of chlorophyll in the stream is followed by an assessment of the changes in water quality in...
