Only happens in high energy rivers, bed load rolls along in contact with the river bed 5 of 11 deposition when the river loses its energy and it drops what it is carrying 6 of 11 erosion where the bed and the side banks can be worn away by either the force of the water or other means 7 of 11 hydraulic action where the water crashes into small gaps in the side banks, compressing the air and forcing the rocks apart 8 of 11 attrition where the flowing water picks up rocks which smash into eachother, wearing them down into smaller rounder particles 9 of 11 abrasion where the water picks up rocks from the river bed and forces them to smash against the river banks, making the banks wider 10 of 11 corrosion where minerals such as calcium carbonate are dissolved in the river water causing remaining parts of the banks to collapse, widening the river banks 11 of 11
