Meandering Rivers and Braided Rivers
Course Objectives
- To gain advanced knowledge on River dynamics mainly applicable to Water Resources Engineering
- Help students to develop an understanding of solution of fluvial hydraulics which is an important part of River flow studies.
- Provide idea on sediment flow computation, complex velocity distribution, scouring and erosion patterns in a river system
- Study on Meandering of rivers Braided river
Course Outcomes
The course covers the important aspects on sediment transport , river meander, braided rivers etc in free surface flow studies. The students will be feeling comfortable to apply erosion and sedimentation knowledge for their further studies and modified design aspects.
