Study on Urban Flood Prevention and Drainage System of Dongyin Canal Guided by Ideas of Systemic Governance
Guided by the ideas of systemic governance,one-dimensional hydrodynamic model and hydrodynamic water quality coupling model were used to hydrologic and hydraulic calculation and simulation of water quality of Dongyin Ca-nal.Considering water quality protection for water works and section of national examination,the flood prevention and drainage system of Dongyin Canal was proposed,which concludes dredging 13.5 km riverway,widening to 50 m in 2.4 km riverway,building a flood-diversion sluice(W=30 m,Q=299 m3/s),building 23 km dyke,and building Humen pump station(Q=70 m3/s).With all these projects,the flood control standards of Dongyin Canal will reach 2%fre-quency.By closing all the sluices,letting water out from Humen sluice and pump station,the water quality of Sisheng Section of national examination can reach to grade Ⅲ.The system has coordinate efforts on flood,tide and pollution con-trol.The results of this article can be reference for policy decision of the government and similar engineering design.
