ANALYSIS OF THE EUTROPHICATION FACTORS IN THE SUTLA RIVER BASIN

The Sutla River forms the border between Slovenia and Croatia. The area of Sutla river basin is 590, 6 km2, of which 78% is located in Slovenia, and the rest in Croatia. The nature retention function for flood control purposes and wetland ecosystems have developed on the edge and at the bottom of the nature retention/reservoir, the area of the entire reservoir as well as the entire riverbed of the Sutla River was declared a NATURA 2000 site. For the planning of remediation measures according to the WFD and reducing the risk of eutrophication, the DPSIR approach with use of spatial data, quantification of nutrients by Soil Water Assessment Tool model (SWAT), the analysis of physico-chemical and biological indicators for good water status and measures within integrated water management are analysed.
