After the August 2002 floods, the Vienna University of Technology (TU Wien) was commissioned to develop an online flood forecasting model for the Kamp River in northern Austria, which was heavily affected during that event. The operational forecasting model has been in use since March 2006. As a result, 18 years of additional hydrological data (precipitation, air temperature, and discharge measurements) are now available for evaluating the hydrological flood forecasting model. The simulated and forecasted discharges at the gauge stations within the model area will be assessed for their forecast quality. A detailed analysis of the simulation results aims to identify potential improvements (parameters, model structure) for the hydrological forecasting model for the Kamp River. Based on the evaluation results, a concept with specific improvement measures will be developed.
