Gradually varied flow analysis
WebBackwater (water surface) Profiles: Backwater profiles for gradually varied flow use discharge, channel geometry, conservation of energy, and estimates of friction losses (usually based on Manning’s Equation) to calculate the water surface elevation in the channel as a function of distance from a channel location of known depth.

WebBoth gradually varied and rapidly varied unsteady flows are possible, and the same general rules for analysis apply as for steady flow. The zones of rapidly varied flow … WebAbstractThe depths for a steady, gradually varied flow in a rectangular open channel with infinite widthobtained analytically by the Bresse formula and numerically using trapezoidal rule for integration havebeen compared. It has been shown that numerical integration may generate significant errors of flowvalues for looped river networks.
WebGeneral form of the Gradually Varied Flow equation is: y = Water depth, measured from culvert bottom to water surface. x = Longitudinal distance, measured along the culvert bottom. The Friction slope is approximated … WebGradually varied unsteady flow: Passage of flood wave in a river. Rapidly varied steady flow: A hydraulic jump below a spillway or a sluice gate. Rapidly varied unsteady flow: A surge moving up a canal breaking of wave on the shore. Spatially varied steady flow: Flow over side weir or flow over bottom rock.
WebGradually and rapidly-varied flow are defined, and independent methods of analysis are proposed. Bakhmeteff's concept of specific energy is introduced, and the conditions for critical flow are discussed. The concept of specific force is introduced in the process of momentum conservation, and the phenomenon of the hydraulic jump is analyzed.
