... 过水断面面积A：垂直于 流向的横断面(Section area) 水面宽(Width of water surface)B水深(Depth)h： 底坡(Bottom slope)i ：明渠 纵断面上渠底线的坡度 因θ很小，通常可取 s z s z z i 1 2 sin l z z tg i 1 2 sin ...
The effect of the bottomslope on the rapid flow shock wave is theoretically studied with the relevant model test herein.
通过理论分析研究了底坡对急流冲击波的影响，并进行了相应的模型试验研究。

The uniformity of water distribution is related to section cross, water depth, trough width, pore size, pore distance and bottomslope.
配水的均匀性与配水槽的断面、水深、槽宽、孔径、孔距、底坡等因素有关。

The results of the simulation also show that it is not suitable to install bottom sill or bottomslope in the project which have side-inflow forebay for improving the flow pattern.
