单一河道走向临海城市排洪方案研究

摘要

针对河道走向单一的沿海城市的涝水、潮水特点,提出了新开河道的排洪方案.以赣榆港区主城区为例,采用单一变量法对有无新开河道情况下原有各河道的水位情况进行比较.结果表明,新开河道可使地势高的河道水位明显下降,可将地势高的水系涝水排出,且加强了个河道的水力联系.%Aiming at flood and tide characteristics in the coastal city with single river channel, put forward the new open channel drainage schemes. Taking main district of Ganyu port city as an example, using a single variable method to compare the original water level without new river channels. The results show that the new channel can reduce the water level at a high river course obviously, discharge flood, and strengthen the hydraulic connection.
