Study on Flood Simulation in Yi River based on TOPMODEL
Journal Title: Science Paper Online - Year 2006, Vol 1, Issue 5
Abstract
The TOPMODEL, coupling with the infiltration excess mechanism, was used to simulate flood events in Dongwan basin in the upper stream of Yi River. The Green-Ampt model was used to calculate the infiltration excess runoff, then, TOPMODEL was used to simulate the runoff yield in the dynamic saturation areas and base flow. Sub-basins were divided according to DEM, and the model was used to simulate the hydrograph at outlet of each sub-basin. Muskingum method was used to route hydrograph of each sub-basin to the basin outlet. The results obtained from the above procedure were also compared to the results from a general TOPMODEL that was used to the basin without partition of sub-basins. It is shown that the TOPMODEL considering the infiltration excess mechanism is more reasonable for runoff simulation to the studied basin.
