摘　　要：在沿海地区的河流及其入海口、海岸海防工程规划设计中,由于存在海潮对河流洪水的顶托作用,因此需要进行洪潮遭遇分析。计算了某流域河口处设计潮位和设计洪水,并按以洪水为主和以潮水为主分析了洪潮遭遇组合情况,用图示法表示了河口地区洪水和潮水遭遇的相关性,辅助确定河口洪(潮)水位。In the planning and design of rivers and their inlets in coastal areas and coastal defense projects,due to the jacking effect of sea tide on river flood,it is necessary to analyze the encounter of flood tide.In this paper,the design tide level and design flood at the estuary of a basin are calculated,and the combination of flood and tide encounter is analyzed according to flood and tide.Graphical method is used to show the correlation between flood and tide encounter in the estuary area,which helps to determine the flood(tide)level of the estuary.

关 键 词：洪潮遭遇 潮水位 降水量 相关图
