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勻流問題之一，是關於水麪曲線的定性分析和定量計算。
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.
影響水麪線及槽蓄曲線的因素可概括爲河段自然地理狀況及水流情勢。
Strength, volumetric strain and permeability coefficient, and even moisture-distribution above ground water surface can be determined by the soil-water characteristic curve.
根據土水特征曲線可以確定非飽和土的強度、躰應變和滲透系數，甚至可以確定地下水麪以上水份分佈。

水麪線
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.
