Abstract

The MUSKINGUM-CUNGE METHOD is still frequently used for FLOOD ROUTING. During the last decade different modifications were proposed for this method to increase its accuracy. However, difficulties arise in the selection of an appropriate ‘‘reference’’ discharge for evaluating the routing parameters and in the small volume loss that can occur. In this research in order to study the applicability of the different schemes of the MUSKINGUM-CUNGE METHOD in field conditions, some observed flood events of Karoon River, Western Iran, have been routed by these schemes and the results were compared with that of the observed values of the downstream end of the reach as well as outputs obtained by the DYNAMIC WAVE model. The results indicated that the studied schemes generally provided reasonable output in comparison with the observed hydrographs. Also the discrepancy among the results of these schemes was not significant. In addition, the computed results reasonably concurred with that of DYNAMIC WAVE model. Finally, the sensitivity analysis of computational grid size is performed. The results showed that the effect of changing the time step rather than the space step is bigger on the output of models.
