为防洪、航运、供水、排水及河岸洲滩的合理利用,按河道演变的规律,因势利导,调整、稳定河道主流位置,以改善水流、泥沙运动和河床冲淤部位的工程措施。河道整治分两大类:①山区河道整治。主要有渠化航道、炸礁、除障、改善流态与局部疏浚等;②平原河道整治(含河口段)。主要有控制和调整河势、裁弯取直、河道展宽及疏浚等。中国有4000年前禹疏九河,导流入海的
For flood control, shipping, water supply, drainage and rational utilization of riparian beaches, according to the law of evolution of the river course, make the best use of the situation to adjust and stabilize the mainstream of the river course so as to improve the engineering measures of water flow, sediment movement and riverbed scouring and silting. River regulation in two categories: ① mountain river regulation. The main channel diversion, reefs, in addition to barriers to improve the flow and local dredging; ② plains river regulation (including estuary). Mainly to control and adjust the river, cutting straight bend, river broadening and dredging. There are 4,000 years ago in China, Yu Shu nine river diversion into the sea
