WebDec 12, 2009 · Sometimes the analysis of the steady gradually varied flow in channel network is carried out using the unsteady flow equations, i.e. the system of Saint Venant equations. Starting from the hydrostatic state, these equations are solved numerically with the boundary conditions corresponding to the required final steady state. Consequently … The energy equation used for open channel flow computations is a simplification of the Bernoulli Equation (See Bernoulli Principle), which takes into account pressure head, elevation head, and velocity head. (Note, energy and head are synonymous in Fluid Dynamics. See Pressure head for more details.) In open channels, it is assumed that changes in atmospheric pressure are negligible, t…
