苏北主要入海河流排涝设计潮位与潮型分析

Analysis on designed tidal levels and types in drainage of major sea-going rivers in north Jiangsu Province

苏北沿海地区各泄洪河道在排涝过程中,受到潮汐变化的影响,每条河流因其河床构造、入海口所处的地理位置及河海交汇处的水文特征不尽相同,影响程度也存在着较大的差异。因此,在该地区进行水文信息预报、水利工程建设设计、防洪工程系统能效评估及沿河资源开发利用等项工作时,必须掌握每条入海河流受潮汐变化对排涝过程产生影响的程度与规律。介绍了一种排涝设计潮位和排涝潮型的估算分析方法,并对苏北沿海地区主要入海河流代表站的排涝型设计潮位和潮型进行了分析。

We propose a method to estimate design tidal levels and types for drainage based on practical design of tidal levels and types for drainage, and furthermore, analyze the design tidal levels and types of the representative stations of major sea - going rivers in coastal areas in north Jiangsu Province. The results show that this method is feasible in the design of hydraulic project, flood control project and drainage project in the coastal rivers in this area.
