Abstract

Classification of chemical status of rivers for water management planning in Lake VBrtsjarv catchment area, Estonia A. Janet & U. Mander Institute of Geography, University of Tartu, Estonia. Abstract The EU Water Framework Directive devotes close attention to the ecological assessment of surface waters and the measure of achievement of implementation programmes. Based on long-time monitoring data that consisted in gathering water quality information from rivers in the Lake Vbrtsjarv catchment area in Estonia, classes of rivers with regard to water quality were devised. Secondly, a priority map at a river basin level for integrated water management planning was developed. The purpose of this study was to analyse trends in the water quality of medium-sized (from 108 to 1270 krn2), predominantly rural river basins in southern Estonia. Chemical monitoring data from 1980-2000 were used in this study. The total current ecological value of river water quality in the Lake Vbrtsjarv catchment area asse
