Abstract: The numerical model CCHE2D has been applied to simulate flow field for the Lauffen Reservoir on the Neckar River, Germany. The model predicted water surfaces and velocity fields under unsteady states. Manning's coefficient was identified in the model calibration using measured field data. The calibrated model was then validated using more filed data measured during several flood events. The results showed that predicted water surface elevations were in a good agreement with the field measurements and imply that the CCHE2D model can simulate a unsteady natural river channel flow with a complicated geometry with sharp bends and wider flood plains.
