Unsteady Flows in Rivers and Pipes (Graduate course)

Course Overview

This course covers the introduction and analysis of unsteady flows in open-channels (e.g., rivers). Strong emphasis is given to application of efficient numerical techniques and computational procedures to river routing and flooding. The course focus primarily on one- and two-dimensional flows.
