Fluvial transport is the process by i beg your pardon a river carries that is load. Load varies in size from big angular boulders in the upper course to fine, exposed sedimentin the lower course. Fill mainly comes from weathered material that has actually rolled down the hillside right into the river bed. However, it likewise comes from the eroded bed and also banks of the river.
Rivers transport product in four ways:
Solution – minerals are dissolved in the water and also carried along in solution. This typically occurs in areas where the underlying bedrock is limestone or chalk;Suspension – fine, light product such together alluvium is carried along in the water. This is known as exposed load. The fill bounces in line v the rise and fall in the velocity of the river;Saltation – small pebbles and also stones space bounced follow me the river bed;Traction – huge boulders and also rocks room rolled along the flow bed. The load carried this method is dubbed bed load.

Processes of transport by a river
The video clip below mirrors the activity of sediment in a river. Notification the different types of procedures of transport at work including traction (rolling of product over the river bed) saltation (bouncing movement) and suspension (material exposed in the water).
