The emphasis in this chapter is on the man‐made open channels associated primarily with environmental engineering systems. It is limited to spatially‐constant flows, which include branching flows. The initial sections of the chapter consider only steady flows, that is, flows which are (or may be assumed to be) temporally constant. A later section introduces the subject of time‐varying flows in channels. The relatively large characteristic dimensions of the channels of concern generally result in turbulent flow conditions. The dominant analytical complexity attending open‐channel flows is the addition of cross‐sectional area as an unknown. Unlike pressure conduits, care must be taken in the selection of a starting position and the direction (upstream or downstream) in which computations proceed. The starting conditions are most often conditions of critical flow or uniform flow , important concepts which are addressed. Later sections deal with flows undergoing transition from one control condition to (or toward) another. Practical applications are interwoven into the conceptual scheme.
