一、概述在太湖流域规划及防汛、抗旱等调度管理中,涉及苏南沿江口门引排能力时,经常用到开闸率的概念.所谓开闸率,即在一定的内河代表站水位下和一定的外江潮型时,沿江某一节制闸在一潮中所能引水或排水的最大历时与一潮总历时之比率。70年代,原长江流域规划办公室会同苏、浙、沪两省一市有关单位曾就1954年梅雨型和1962年台风雨型等洪涝年份作过规划工情下排水开闸率的分析研究工作,但对干旱缺水年份现状工情下的引水开闸率则缺少研究。这次我们结合水利部太湖流域规划管理局委托的“苏南沿江口门
First, an overview In the Taihu Lake Basin planning and flood control, drought and other dispatch management, involving the southern edge of the port cited capacity, often use the concept of the rate of the gate. The so-called gate-rate, that is, in a certain river station under the water level And a certain type of the outer ripples, the ratio of the maximum duration of water diversion or drainage and the total tidal wave of a certain flood control gate along a river in a tide. In the 1970s, the former Planning Office of the Yangtze River Basin together with the relevant departments of Jiangsu, Zhejiang and Shanghai provinces and municipalities once conducted analysis and research work on drainage gate-under rate under the planning conditions of the 1954 Meiyu-type and the 1962 typhoon- However, the current situation of drought and water shortage in the current situation under the gate-access rate is the lack of research. This time we combined with the Taihu Lake Basin Planning Authority Ministry of Water Resources entrusted ”southern Jiangsu mouth
