No student outcomes specified.
Course Learning Outcomes. Students will:

1. Be introduced to the Navier Stokes equations governing fluid flow.

2. Apply integral equations (mass, energy and momentum concepts) to describe rapidly varied flow.

3. Apply the Manning Equation and Chezy Equation to describe uniform flow.

4. Classify gradually varied flow profiles.

5. Recognize the unsteady flow equations and understand the concept of characteristics.

6. Develop simple software that solves open channel flow equations, and apply the software for analysis and design purposes.
