Use of computers in sediment computation by the original Einstein method

Since the computation of sediment loads in rivers and channels are becoming increasingly important in river basin development and water resources management and planning as well as in the consideration of the design criteria for any type of hydraulic structure, attempt has been taken in this paper to develop an efficient method to compute the sediment loads in rivers and channels. The idea used in this method is that of Einstein but modifications are made to overcome some of the limitations and disadvantages in the original method. To implement computers to reduce calculation time to solve the problem, the standard curves used in Einstein method are converted to suitable polynomial by using APL (A PROGRAMMING LANGUAGE) technique of fitting polynomials. In addition, the integrals of the bed load function are evaluted numerically using Simpson rule adjusted for appropriate number of steps required to obtain the desired degree of accuracy.
