The implicit method of solution of the continuity and momentum equations of flow in open channels was used to study problems of unsteady flow in natural rivers. A computer program was written to obtain solutions along the river with appropriate boundary conditions. The first problem relates to flood flows in the James River. A storm in December 1967 was analyzed and the comparison between the computed and measured flows was good. The second problem relates to the study of low flows from Holcomb's Rock, Virginia to Bent Creek, Virginia in the James River. Attempts to model these flows showed that the program in single precision was unstable. However, when the same program was run in double precision, good agreement was obtained between measured and computed flows. The last problem was the analysis of waves in a pump-storage reservoir. Data was obtained on flows in Leesville Reservoir, on the Roanoke River, Virginia. (Author)
