Runoff simulation in the Upper Oder catchment during the flooding event 1997 with a coupled atmospheric/ hydrological model

Abstract

Two alternative modes of the land-surface scheme SEWAB for the hydrological processes describe the two flood waves in the upper Oder catchment of the July 1997 flooding event with similar and reasonable accuracy. With the topographic index approach the peak value is slightly underestimated but correct in time while the reservoir concept shows a slight overestimation with a delay of one to two days. The interpolated observed and the simulated precipitation fields show remarkable differences in space and time. Consequently, the discharge also exhibits larger deviations.
