River Transportation

?
Rolling/Traction
Large boulders and stones are rolled along the river bed as they're too heavy to be picked up. This happens when the river is in flood. They may erode by attrition is one rolls into another.
1 of 10
Hopping/Saltation
Large particles and small pebbles can be picked up by the river but are too heavy so the river drops them, so they hop downstream, touching the bed at intervals.
2 of 10
Suspension
Small particles are carried in water as they are lighter. Most of the load is carried in this way. The Mississippi carries 136 million tons of material each year in suspension
3 of 10
Solution
Dissolved material and salts are carried in solution.e.g limestone and chalk. This is the solute load
4 of 10
River Channel
The area outlined by the bed and banks in thich a river flows.
5 of 10
River Bed
The bottom of a river's channel.
6 of 10
River Banks
The sides of a river's channel - left and right banks.
7 of 10
Velocity
The speed of the river. The main current is usually down the middle of a river.
8 of 10
Discharge
The amount of water passing a certain point at one time. Peak discharge occurs after heavy rains.
9 of 10
Load
The material in the river. Pebbles are rounded and smoothed by a river because of erosion. More load is found downstream, but the size of the load is smaller.
