Abstract: Variou Weir structures are Used is waterway and hydraulic engineering.The weir pattern has agreat effect on the discharge capacity,flow structure and erosion-depositions condition,Based on thetypical medel test, this paper studies the folwline pattern over a board weir and showes it as Y =Ke

Key words: folw over weir, board weir height, threshold face

摘要： 在水道工程的建设中，各种类型的堰利用率很高．堰的坝型和坝高的选择直接影响到过水能粒本文通过宽顶堰的模型试验，再现越障水流现象并对过堰水流流型进行探讨，以便为水利工程设计提供可靠的依据．
