A Study on the South Drainage System of Main River in Hangjiahu Plain River Networks
Eastern Hangjiahu Plain is one of the eight water conservancy zonings of the Taihu Lake Basin.The water surface ratio is 8.06%.Rapid drainage of plains has always been an important issue in water conservancy planning.The water flow is complex in Eastern Hangjiahu Plain.In order to strengthen research on drainage and control of plain river networks,by dividing the"wave velocity zone"and"flow velocity zone"of the plain river network,further differentiation is made on the factors affecting plain floods,deepening the understanding of the motion law of flood waves in the plain river network.Water level measurement points weve arranged along the main drainage river channel,observing and analyzing the dynamics of water level changes within the plain,fully understanding and verifing the"wave velocity zone"and"flow velocity zone"of the plain river network.It provides evidence for the division of flood-carrying capabilities of plains river networks,so that corresponding engineering measures can be taken for targeted improvements.It also provides guidance for the next step of implementing the eastern channel in the Eastern Hangjiahu Plain.
