In this case, the water table is not flow surface and there is no "seepage surface" on the side walls of drainage river channel.
该条件下的潜水位面不是流面，在排水河渠边壁也不存在所谓的“渗出面”。
Open channel flow is a sort of generalize for water flow phenomenon, which water stream with free surface be leashed by solid boundary with finity scale.
明渠水流是对具有自由表面的水流在有限尺度的固体边界约束下流动现象的一种概化。
The model is applied to calculate the transition water surface profiles from supercritical to gradually varied flow or from gradually varied flow to supercritical flow in rectangular open channel.
应用该模型对矩形明渠中缓、急流过渡的水面曲线进行了数值计算，并与理论解进行了比较。
The factors affecting the water-surface profile and channel storage curve may be summarized as the physical geographical condition and the flow regime of the river reach.
影响水面线及槽蓄曲线的因素可概括为河段自然地理状况及水流情势。
As for the water resources from the surface water and natural raining, it is mainly to grout and seal the water conducted channel. Good water prevention and control results ware obtained.
对于水源主要来自地表水和大气降雨的，对主要导水通道进行注浆封堵，可以取得很好防治水效果。
