摘  要:
This paper,based on Manning Formula and the theory of classical hydraulics, the method of experimentation and studying on the roughness coefficient n of varied litter in laboratory has been researched.The steps in the experimental process,the calculation of ex- perimented data,and the process of the data analysis have also been explained in detail.And at the same time the paper points out the problems which should be noticed in the experimen- tation.
