Experience of model integration and Pareto frontier visualization in the search for preferable water quality strategies

A real-life application of a new approach to integrated assessment and screening of water quality improvement strategies in large river basins is presented. The approach is based on the integration of diverse data and mathematical models as well as on the application of interactive visualization of the Pareto frontier. The case study water quality planning in the Oka River, the Volga River basin, is presented within the framework of a DSS for screening water quality planning strategies. The Decision Support System (DSS) was commissioned by the Russian Federal Ministry for Natural Resources within the Federal programme ‘‘Revival of the Volga River’’.
