River Networks Fluidity Classification Analysis Based on Two Dimensional Numerical Model and Hydraulic Characteristic

摘要：

　　Water Diversion from outside of an urban is the effective method of solving city water pollution.Because the boundary condition is different,quantity of flow distribution is different for the every river water.The velocity is also different.The velocity of some river channels is even much smaller.Only the fluidity of every river is known well,can the measures of improving river water environment be found out.The two-dimensional finite element method mathematical models of the river network is established and verified.Bases on the established and verified planar 2-D unsteady river networks tlow finite element model,the velocity size and orientation of the every river and water levels are calculated.The numerical simulation research and analysis shows that the quantity and velocity of flow distribution are both different for every river water.The velocity of some river channels is even much smaller.According to the hydraulic characteristic such as velocity size and fluidity,five classifications are made,and some measures of improving and harness of water fluidity are provided and analyzed
