Deposition
The process of a river dropping sediment or rocks.
1 of 10
The amount of water flowing through the river.
Discharge
2 of 10
Hydraulic action
Sheer force of the water causes erosion.
3 of 10
Abrasion
Sediment and rocks carried by the river rub against the banks and bed of the river, it erodes.
4 of 10
Attrition
Rocks in the river smash and rub against each other, smoothing the rocks.
5 of 10
Solution
The water dissolves the particles, creating a solution.
6 of 10
Suspension
Fine particles are suspended and carried through the river.
7 of 10
Saltation
Small rocks and pebbles are bounced along the river bed.
8 of 10
Traction
Large boulders and rocks are rolled along the bed.
9 of 10
Lower course
As the river approaches the mouth, velocity and energy increase due to increased discharge. The river performs more lateral erosion making the channel wider, and smoother. As a result there is less turbulence and friction, water flow more efficient.
