Title: Study on Rechecking Analysis of Flood Control Capacity of River Embankment under Changed Conditions
Abstract: On the basis of historical flood calibrated river roughness,one-dimensional river flood model is established for simulating the flood routing when design flood occurred.The rationality of simulation result is checked with the surface profile calculated by different methods.By analyzing the quantitative relationships between simulation water level and guaranteed water level and levee height,it discusses the impact of shoal roughness on the flood level.The results show that parts of cross section levees in downstream of the Shifosi Reservoir do not attain the design standard flood and shoal roughness has a great impact on flood water level,which need for maintenance and reinforcement.
