The qualitative analysis and quantitative calculation about watersurfacecurve 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 watersurfacecurve 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。

Water flows through bend do a curve driving campaigns and the surface patterns and flow structures become adjusting and changing.
