Student Learning Outcomes

1. Apply the principles of conservation of mass and mechanical energy to the analysis of 1-dimensional open-channel flows. Evaluate, from physical and design perspectives, the applicability and limitations of Bernoulli's principle to prediction of 1-d open-channel flows.
2. Apply the momentum principle to examples of open-channel flows such as hydraulic jumps or supercritical flows. Analyze uniform flows and evaluate applicability to natural or artificially created open-channel flows.
3. Predict water surface profiles using numerical solutions of the governing equations under steady flow conditions, for realistic cases such as lake connections and natural or man-made rivers. Derive hydraulic performance graphs using the general theory of backwater profiles.
4. Synthesize major (basic) elements of the unsteady flow theory, and the derivation of the Saint-Venant (shallow-water) equations. Apply basic concepts of this theory to the analysis of hydraulic routing of floods, and the use of standard hydraulic models.
