- River energy-not used for erosion = not lost through friction = transport a river's load.
A river obtains its load from two main sources:
- Material- washed, or has fallen, into the river from the valley sides
- Material- eroded by the river itself from the bed or banks
Capacity and competence.
- Influenced by the velocity = therefore the discharge of the river
- Capacity of the river = a measure of the amount of material it can carry =the total volume of the load.
- Competence of a river = the diameter of the largest particles that it can carry for a given velocity= the faster flowing a river = greater the turbulence = river is better able to lift particles from the river bed.
