How do the
geomorphological
processes operate
to form river
features in the River
Darent?
- Deposition
- Occurs when
the river
loses energy
and is unable
to transport
large loads
- As river energy
decreases the carry
load falls and large
particles are
deposited before
anything else
- Erosion
- Abrasion
- The load (sand, shingle,
boulders etc.) is carried in the
water and rubs against the
river bed and bank and wear
them down
- Attrition
- Movement of river makes laod
crash together so sharp edges are
broken down and become more
rounded and smaller
- Solution
- Rocks dissolved by acidic water
- Hydraulic Action
- Air present in gaps is trapped
and compressed by prerssure
of water. Over time pressure
increases and weakens the
rock, eventually breaking it
- Transportation
- Traction
- The largest rocks roll
along the bed by the
force of the water
- Suspension
- Silt and clay are supported
within the water
- Saltation
- Sand and
pebbles bounce
along the bed
- Solution
- Minerals dissolved
in water are carried
in the water flow
- Human Intervention
- Water Mills produced energy
- Paper Mills, e.g. Horton
Kirby Paper Mill
- Flour Mills, e.g. Longford Mill
- Transport
- Water companies
