SEDIMENT TRANSPORT IN THE YELLOW-RIVER

Yang's unit stream power formula is modified for the computation of to tal bed-material load in a sediment-laden river with a high concentrat ion of fine suspended materials. Theoretical and laboratory studies in dicate that modification can be made on the values of particle fall ve locity, flow viscosity, and relative specific weight without any chang e of the coefficients used in Yang's original formula. Comparisons bet ween computed results from the modified formula and field indicate tha t the modified formula can be used to compute total bed-material load in the Yellow River with accuracy.
