water-surface curve

基本解释

The qualitative analysis and quantitative calculation about water surface curve is one of problems on non-uniform flow in water conservancy works.
水利工程中提出的非均匀流问题之一，是关于水面曲线的定性分析和定量计算。
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。
Strength, volumetric strain and permeability coefficient, and even moisture-distribution above ground water surface can be determined by the soil-water characteristic curve.
根据土水特征曲线可以确定非饱和土的强度、体应变和渗透系数，甚至可以确定地下水面以上水份分布。

水面线
By the method of model tests and theoretical analysis, flow form, pressure characteristic, water-surface curve, velocity , air entrainment and energy dissipation have been studied in this paper.
