Abstract: The implementation of the EU Water Framework Directive requires supporting systems for the integrated water resources management. Computer models are powerful tools to forecast the consequences of all impacts of water usage on the ecological system. For the River Spree’s catchment area a steady state water quality model has been developed. Combined with an unsteady water quality model it allows the treatment of problems on different time scales. This paper focuses on the verification of the unsteady water quality module. After introducing the mathematical basics, some ideas for verification are shown using the unsteady conservative solute transport as example. The test cases allow some conclusions concerning the choice of time and space step size.
