River Landscapes
Both
Erosion outside, deposition inside bends.
Key Facts
- Velocity is highest on the outside of bends.
- Flood hydrographs show lag time and peak discharge.
- Hard engineering is effective but expensive.
- Soft engineering works with natural processes.
Key Equations
Discharge = cross-sectional area x velocity
