Significance of Hydromorphological and Sediment Analysis in River Basin Water Quality Management

Abstract

The hydromorphology and sediment management, as part of the integrated water management and achieving environmental objectives of the river basin in accordance with the WFD, are presented in the case study of the transboundary rural River Basin Sutla. Sutla is the border river between the Republic of Slovenia and the Republic of Croatia, with a catchment area of 590.6 km2. The proposed sediment management methodology is based on the surface water bodies’ assessment of water quality status, from the surveillance monitoring, and the impact assessment of the point and diffuse pollution sources in the river basin by the mathematical model SWAT.
