Channel Morphology
The study of the channel pattern and the channel geometry at several points along a river channel, including the network of tributaries within the drainage basin. Also known as River Channel morphology
Dr. Manishika Jain explains what is channel morphology and the various 5 ways to understand it: 1. Channel Geometry 2. Fluid Dynamics 3. Channel Bed Topography 4. Hydraulic Geometry 5. Channel Types & Patterns
What to Study?
Factors Affecting River Channel Morphology
Discharge
- Volume of water flowing per unit time.
- High discharge causes erosion, transportation, and deposition in high rate
Velocity
- Fast moving rivers carry greater amount of materials.
- Depends on the gradient and discharge of river.
Lithology
- Nature of rocks effects channel morphology.
- Some rocks are easily eroded than others.
Load
- Loaded river will not erode and transport the materials
