Open Channel Flow - Institute for Transportation

Mar 02, 2020 · Steady and Unsteady Flow: A steady flow is when the discharge passing a given cross-section is constant with respect to time. When the discharge varies with time, the flow is unsteady. The maintenance of steady flow requires that the rates of inflow and outflow be constant and equal.
