A Study on Bed load Discharge

Based on the dimension and rule of sand waves,a equation of bed load discharge is given in this paper. It can be used in calculating on bed load discharge of uniform and non - uniform sand,and has been checked by hundreds of test data and field data,and the result shows that it has a good agreement with test and field data in all kinds of strength of bed load transport.
