Steady free surface flow

Steady free surface flow is Chapter 13’s topic which starts with the consideration of sub- and supercritical flow. From the Bernoulli equation for free surfaces, we make our way to the consideration of flows under sluice gates or over weirs, through syphon weirs or Venturi channels. Subsequently steady-state, uniform conditions and the describing equations are elaborated before nonuniform conditions are discussed. The chapter ends with the direct step method, for which, again, open-source codes are provided. At the end of the chapter the reader can solve problems of nonuniform free surface flows.
