Determining the Coefficient for Sediment-carrying Capability Formula of Two-dimensional Plane

Sediment-carrying capability of water flow means the maximum capability of water flow to carry sediment.The sediment carrying capability formula could develop sediment 2D plane models,and the key problem is to determine its coefficients in the best way.Generally,determining the coefficient for the sediment carrying capability formula must use the survey data under the real applying,this paper applied the least square method and grey incidence degree to determining the coefficient for Li Yi-tians sediment-carrying capability formula of 2D plane.
