Operational water quantity management in a river basin

The real-time water quantity management of complex water resources systems can be successfully supported by mathematical models. Since there were no models available for integrated water management on the catchment scale, a generally applicable model system for quantitative water management has been developed and adapted to the watershed of the River Ruhr in Germany. The first results attained with this model system in the Ruhr catchment basin show that it is a powerful tool for operational water quantity management and is able to simulate a differentially structured watershed with high anthropogenic impacts. The use of this model has enabled Ruhrverband to make crucial improvements and increase the objectivity of operational water quantity management.
