Course Objectives
- Provide an introduction to the field of river flow mechanics which is the basic of flow mechanism in a river. This is the most important part of the Water Resources engineering.
- Help students to develop an understanding of solution of free surface of flow which is an important part of fluid mechanics.
- Illustrate the design methods of cross section of channels for different flow and geometry conditions.
- Provide idea on flow computation, velocity distribution in a river or artificial channel with complex geometry, plan form and flow conditions ( steady and unsteady).
Course Outcomes
