| Abstract |
The usefulness of hydrodynamic river models much depends on the accuracy of the model. The uncertainty in the results of hydrodynamic river models typically originates from uncertainties in the model parameters (calibration uncertainty), model schematization and input data. Based on a detailed insight in the river system, the modelling process and its shortcomings, most efficient model improvement actions can be designed.In this paper, several model improvement actions are suggested and tested for the hydrodynamic model of the Demer river in Belgium. A detailed model performance evaluation is conducted for that case based on field measurements of river water levels and discharges at different places along the river. The evaluation includes comparison of observed and simulated rainfall-runoff and river peak flows, low flows, cumulative volumes and empirical extreme value distributions. |
