Analysis of Flood Calculation in the Design of a River Treatment Project
The design calculation and analysis of flood in river treatment engineering is a very important technical design content to provide scientific basis for river treatment engineering.Therefore,the practice case is analyzed based on the analysis of key points of flood calculation design of river control engineering in Fengzhuang section of Liaohe River.The results show that under the condition of insufficient hydrological observation data,in order to calculate the flood results of the downstream section of the project,on the basis of collecting and sorting out the existing hydrological results in the basin,three medium-sized reservoirs and a small(1)reservoir project with large regulation and storage function at the upstream of the design section are subject to flood combination calculation.According to the regional distribution law of rainstorm and the flood hydrograph of each division,the flood results of each division are obtained through trial calculation,so as to analyze the design flood results of the downstream flood control design section.Through comparative analysis and verification,this design method is feasible and can provide reference for similar projects.
