| Abstract: | In this paper,the size distribution of non-uniform bed materials is described through the sum of density fnuctions of normal distribution.It is a method used to analyze the action of each part of mixture bed materials in transport processes in alluivial streams.The exactitude of the above method is verified by field data.The results are satisfactory.Finally an example for application is given. |
