摘要
在天然河道治理规划中,必须对河道断面进行排涝复核。以南通市为例,对平原河网地区的排涝复核计算方法作了探讨,介绍了河网概化、排涝流量计算、水面线推求以及水位平差等技术问题,可为类似地区的河道整治规划提供参考。
The drainage discharge in river cross section must be re-checked in the program of river regulation.Taking Nantong City as an example,the re-checking methods of the drainage discharge of main rivers in the coastal plain are discussed,and the river system generalization,the calculation of the drainage discharge,the inference of water surface profile and the range of water level and so on are also introduced.This result can provide inferences for the river regulation in similar areas.
