针对除涝计算中外海潮型缺乏定量标准的现状,以崇明岛为例,利用一维数学模型,研究了同一设计雨型下外海潮位对滨海地区除涝高水位的影响。研究结果表明:同一设计雨型下,滨海地区除涝高水位与外海潮型密切相关,与最高潮位出现时刻也有关联。
Aiming at the present situation of lack of quantitative criteria for tide-type tide in waterlogging calculation in China and abroad, taking Chongming Island as an example, the one-dimensional mathematical model is used to study the influence of the tide level of the downstream rainstorm under the same design on the high waterlogging level in coastal areas. The results show that under the same design of rain type, the high waterlogging level in coastal area is closely related to the outer tide type and also to the moment when the highest tide level appears.
