摘　　要：跌水为水利工程中一种较为常见的落差建筑物,特别在我国广大丘陵塬坡地区的渠道输水工程中采用的较为普遍。本文从动量角度来处理缓坡上自由跌水作为量水设施的问题,在近似假设条件下得出半经验半理论公式,该公式反映了缓坡上EDR与坡度和糙率的关系。Water down is a more common water drop building in Water Projects,especially in China＇s vast channel water engineering slope hilly plateau region is more commonly used.From the point of view to deal with freedom of momentum as the amount of water facilities or water on the gentle slope of a problem,come under similar assumptions SEMI theoretical formula that reflects the relationship between EDR and on the gentle slope and roughness.

关 键 词：矩形渠道 缓坡 EDR(边缘水深 临界水深)
