Water Quality Management of a Sub-Watershed of the River Elbe

Abstract

Applying multi-objective decision making methods to water quality management tasks optimal compromise solutions between ecological and man-made management operations will be obtained. The DSS REHSPROX was used to compute Pareto-optimal solutions of the DO balance of the Upper Spree River as a part of the River Elbe basin. For this reason, contradictory water quality and economical goal functions describing different management policies are taken into consideration. According to multi-objective optimisation results cost functions for investments are presented.
