River Processes, WJEC
- Erosion
- Hydraulic Action, The force of
flowing water washes away
loose material on the bed and
banks
- Abrasion, (or corrosion) Stones
carried by the river that are
washed into beds and banks
wearing them away
- solution, (or corrosion) Slightly acidic
water that dissolves rocks which are
made of calcium carbonate.
- Attrition, Stones colliding
together are broken down.
- Transport
- Traction, stones are rolled
along the bed by the force
of flowing water
- Saltation, small stones are
bounced along the river bed
by flowing water
- Suspension, particles of silt
and clay float and are carried
along by the flowing water
- Solution, some minerals
dissolve in water E.g.
limestone
- Deposition, if a river slows down due to less water or Less steep land
the river carries less energy therefore some material will be deposited.
