两座水库分别在两个流域,各自有其集水面积、河流长度和河流比降,挖穿分水岭,通过连通渠将两座水库连接起来,两库联合运用,有共同的正常高水位,称其为连通水库。如广东省的高州水库、广西壮族自治区的合浦水库都是此种类型,见图1。这类水库的调洪计算比一般水库复杂得多。下面介绍的是连通渠较短(一般在3公里以 Two reservoirs in the two basins, each with its catchment area, the length of the river and the river drop, dig through the watershed and connect the two reservoirs through interconnecting channels, and jointly use the two reservoirs with common high water levels It is connected to the reservoir. For example, Gaozhou Reservoir in Guangdong Province and Hepu Reservoir in Guangxi Zhuang Autonomous Region are of this type. The flood control of such reservoirs is much more complex than that of a general reservoir. Described below is connected to the canal short (usually 3 km
