Chapter 9
Flow in Open Channels
LEARNING OBJECTIVES
After reading this chapter and solving a representative sample of end-of-chapter problems, you will be able to:
- Understand and apply the basic equations governing flow in open channels.
- Calculate normal and critical flow depths and understand their engineering applications.
- Analyze flows through channel constrictions and identify conditions under which flows are choked.
- Calculate and classify water surface profiles with realistic applications and constraints.
- Analyze transitions between supercritical and subcritical flows.
9.1 Introduction
In open-channel flows the liquid surface is exposed to the atmosphere, which is the reason for using the word “open.” The driving force in open-channel ...
