Transient Open-Channel Flows

Chaudhry, M. Hanif

In the previous chapters, we considered transient flows in the closed conduits. In this chapter, we discuss transient flows in open channels. A flow having a free surface is considered open-channel flow even though the channel may be closed at the top, e.g., a tunnel flowing partially full. A number of common terms are defined, and the examples of transient flows are presented. The dynamic and continuity equations describing these flows are derived, and a number of methods for their solution are discussed. Details of explicit finite-difference and implicit finite-difference method are then presented. This is followed by a discussion of a number of special topics on open-channel transients. The chapter concludes with a case study.
