WebFeb 18, 2024 · The energy equation for a gradually varied flow, the momentum equation, and Manning’s equation provided a solution for Manning’s coefficient. The procedure allowed us to assign a degree of retardance to the species obtained by comparing Manning’s coefficients with those from USDA-NRCS. Results show that retardance … WebExplanation: Gradually varied flow is steady non-uniform because the velocity of water remains constant at a specified point, but it changes from one point to another point. The terms steady and uniform are used frequently in engineering, and thus it is important to have a clear understanding of their meanings.
