Course Description
Design methods (tractive force versus permissible velocity) for open channel conveyances for steady and unsteady flows are the foci of this course. The course will integrate basic theory with applied design issues.

Course Objectives
Students have working understanding of continuity, energy and momentum concepts as applied to open channels. Explore hydraulic jump sequent depth concepts and develop models for predicting sequent depths in rectangular, parabolic and triangular channels. Students can design unlined natural channels and grass waterways using permissible velocity method and tractive force method. Students can estimate cost of alternative channel designs. Student will develop software for routing hydrographs through structures or along stream reaches. Student will develop software that emulates the Einstein or comparable sediment transport approach.
Topical Outline
Note: the course will be taught in a computer lab, with lab exercises being organized around each major heading. A field or wet fluids lab exercise will be customized with detailed content to depend on the student’s research interests. Open channel flow topical outline 1. Fundamental relationships review a.
