水闸、河道控制和水库底孔闸门的设计,讨论了三个不同的工程,它们是威尼斯市的防洪工程、澳洲慕瑞(Murray)河上的溢流堰、新西兰卡拉披如(Karapiro)大坝的泄水底孔。大型水闸的闸门和操作机构往往需要独特的设计,威尼斯挡潮闸就是一个例子。河道控制工程和水电 Sluice, river control and the design of the reservoir bottom gate are discussed in three different projects: Flood Control in the City of Venice, Weir on the Murray River in Australia, Karapiro Dam in New Zealand Drain the bottom hole. Gates and operating mechanisms for large sluices often require a unique design, as is the case with the Venetian tidal barrier. River Control Engineering and Hydropower
