Analysis of Flood Area Composition of Lianjiang River Comprehensive Control Project
The Lianjiang river comprehensive management project adopts a flood control system of"upper storage,middle drainage,and lower expansion",and uses the upstream Xincun sluice for regulation and storage,so that the Park sluice-Xincun sluice section meets the safety discharge requirements.Considering the impact of the regulation and storage of the Xincun sluice,the flood calculation and analysis of the downstream control section is carried out through two unfavorable flood combinations of"interval same frequency,Xincun corresponding"and"interval corresponding,Xincun same frequency",and the larger one that is more unfavorable to the project is selected as the design peak flow of the control section.The calculation method can provide a reference for the combination analysis of flood areas in areas without data.
