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。
However, the unstable flow is usually considered as stable flow in the calculation of natural river water surface curve in order to minimize the calculation work.
但在天然河道水面线计算中，为了节省工作量把不恒定流视为恒定流。
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。
