Effect of Shape of Sedient Particles at the Bed of Open Channel on Friction Coefficient

Hydraulic calculations of the flow in channel and over bank areas of flood plains require an evaluation of roughness characteristics. The Manning roughness coefficient (), Chesy coefficient () and Darsy-Weisbach coefficient () are used to describe the flow resistance or relative roughness of a chann...
