Study of Stream Channel

This study summarizes the main findings on the variations of channel geometry in river courses, specifically the upper course, middle course, and lower course. The variations include width, depth, length, gradient, and wetted perimeter. Factors affecting the geometry are also discussed.

Presentation Transcript

  1. Study of Stream Channel

  2. The variations of channel geometry Group 4

  3. Discussion Topic 1. Summarize and describe the main findings the variations of channel geometry.

  4. River Upper course Middle course Lower course (Area A1&2) (Area B3&4) (Area C5&6)

  5. Channel geometry e.g. the width, depth, length, gradient and wetted perimeter Middle course Lower course Upper course

  6. Area A2 Area B4 Area C5

  7. Compare of the channel Geometry

  8. Upper Course (Area A2)

  9. Middle course Area B4

  10. Lower course (Area C5)

  11. Factors affecting geometry • Upper course Width: less lateral erosion narrow Depth: serious vertical erosion deep Length: straight river course short Gradient: serious erosion steep slope Wetted perimeter: narrow

  12. Middle course Width: more lateral erosion than upper course Depth: less vertical erosion than the upper course Length: meanders exist longer than upper course Gradient: less erosion less steep slope Wetted perimeter: wide

  13. Lower course Width: serious lateral erosion wide Depth: less vertical erosion and deposition shallow Length: ** more meanders exist longest Gradient: deposition gentle slope Wetted perimeter :very wide

  14. ConclusionDescription of channel geometry

  15. The End~~Thank you!
