Riparian Vegetation
What’s the Difference?
Kinds and Amoutsof
VEGETATION
The Role of Vegetation inRiparian Function
• Protect banks• Stabilize channels• Dissipate energy:
→ Slow velocity→Drop sediment→ Stabilize
sediment→Build floodplain
Build Floodplain:
• Increase water storage capacity (sponge)
• Increase recharge
• Absorb floodwater
• Prolonged flow
Riparian Vegetation
1. Slow the water down
2. Retain water on the land longer
