A computer procedure for applying the modified Einstein method

This paper presents an efficient method to compute sediment loads in rivers and canals. The method is based on the technique developed by Einstein but modifications are introduced to eliminate certain limitaitons and disadvantages in the original technique. The proposed method is computerized to reduce the time required to solve a given problem; thus the standard curves used in the modified Einstein's method are converted to a corresponding polynomial by using a Programming Language (APL) technique of fitting polynomials. In addition, the integrals of the bed load function are evaluated numerically using Simpson's rule after adjustment for the appropriate numbers of steps required to obtain the desired degree of accuracy. The results obtained by the proposed method are within a range of 15 percent in comparison to that of the modified Einstein Method.
