- Abstract: The Hydrology Service of the Environmental Agency of the Republic of Slovenia (EARS) carries out systematic measurements of concentration and transport of suspended sediment in rivers. The purpose of suspended sediment measurements is to determine the total amount of suspended sediment concentration and sediment transport at a specific site along the river in one year and in longer periods. The beginning of monitoring of suspended sediment matter in Slovenia dates back to 1955, when sampling started in the catchment areas of the rivers of Mura, Savinja, and Vipava. In 2006, the monitoring network includes stations on 13 rivers. On 6 gauging stations concentration of suspended sediment is measured daily. In this paper, some most important conclusions derived from 50-year monitoring of suspended matter in Slovenia are drawn. Along with regular taking and analyzing of samples, sample taking in exceptional hydrological situations on 8 gauging stations takes place. The important document that integrates river basin management in Europe is the Water Framework Directive. Knowing the amount of suspended matter in rivers is of crucial importance for the assessment of ecological status of waters and for recognition of hydromorphological elements of river basins.
