分洪闸建于河道的一侧，用来分泄河道洪水的水闸。当上游来水超过下游河道安全泄量时，为确保河道下游地区免受洪灾，将超过下游河道安全泄量的洪水经分洪闸泄入湖泊、洼地等预定的分洪区暂时存蓄,待洪水过后,再排入原河道，或泄入分洪道直接分流入海。分洪闸宜建于河流弯道凹岸的顶点稍偏下游处，使能充分利用弯道环流减少或防止闸前泥沙淤积，以保证分洪能力。分洪闸一般采用开敞式。闸底槛高程，多与河道滩地地面接近。闸孔总宽度，应能保证通过最大分洪流量。分洪初期，闸上下游水位差及过闸单宽流量都较大，过闸水流的冲刷能力很强。因此，对分洪闸下游的消能防冲问题，应予十分重视,并须采取有效措施,常需借助水力模型试验研究确定。为使水流平顺地进入分洪道，防止下游河床及两岸遭受冲刷，分洪闸下游连接段一般都较长。鉴于洪水来临时，洪峰历时短暂，分洪闸门应能迅速开启，及时分洪，削减洪峰，保证下游河道安全。因此，分洪闸虽不经常使用，但须经常注意维护管理，并制定严格的闸门操作规程，确保正常运用。中国在20世纪50年代于湖北省建有著名的荆江分洪闸，在河北省建有独流减河分洪闸等工程，迄今已30余年，运行情况良好。
