Methodical Optimization of Model Approaches on Pollutant Balancing in River Basin Districts to Promote the Implementation Strategy for the Water Framework Directive. Final Report on the Project FZK: 370 822 202/01

Within a feasibility study the existing quantification approaches of the model system MONERIS have been methodically developed and their adequacy for modeling in the scale of large river basins has been tested. Additionally, input data sets of spatially and temporally higher resolution have been implemented. The following approaches and methods have been developed based on their relevance for pollutant emissions: water balance and runoff components, sewer systems, erosion and sediment delivery into surface waters, in-stream retention of particulately transported pollutants and the metrological recording of river loads in case of floods.
Furthermore, a consistent and transparent instrument for quantifying and visualizing emissions into surface waters has been developed which will facilitate the reporting commitments. The architecture of MoRE allows users without any knowledge of programing to be able to add other input data and quantification approaches as well as embed other substance groups. Thus this instrument complies with the follow-up and development capabilities concerning the consideration of scenarios.
