明渠导流 河水通过专门修建的渠道导向下游的施工导流方式。明渠导流多用于河床外导流，适用于河谷岸坡较缓，有较宽阔滩地或有溪沟、老河道等可利用的地形，且导流流量较大的情况。与隧洞导流比较，因明渠的过流能力较大，施工较方便，造价相对较低，在地形条件和枢纽布置允许时，用明渠导流的较多。在河床内用分期导流方式修建混凝土坝的初期导流阶段，也常采用明渠导流。在中期和后期导流阶段，可用其他泄水建筑物或在明渠内设底孔或缺口导流，以便使明渠所占的坝段可以施工升高。 布置导流明渠时须考虑：①轴线位置，在地形上尽量利用垭口、溪沟、旧河道等，并力求布置在河湾凸岸的滩地；②明渠进水口要使水流顺畅，距围堰一定距离，防止冲刷坡脚；③进出口高程要根据流量、通航、过木、冲刷或淤积等条件综合比较确定；④明渠断面形式可采用矩形、梯形或复式断面，坡度大于临界坡度，并尽量减小渠道糙率，当渠底为软基时要防止渗漏。 截至1985年，世界上最大的导流明渠是印度乌开堆石坝工程的明渠,设计导流流量45000m3/s。该渠长1372m，渠底最大宽度235m，渠道水深18.25～21m。巴西伊泰普水电站导流明渠宽100～150m，长约2000m，最大导流流量35000m3/s。
