Rivers are 100 times more effective than coastal erosion in delivering rock debris to the sea. Their rate of sediment delivery is equivalent to an average lowering of the lands by 30 centimetres (12 inches) in 9,000 years, a rate that is sufficient to remove all the existing continental relief in 25,000,000 years.
Rock debris enters fluvial systems either as fragments eroded from rocky channels or in dissolved form. During transit downstream, the solid particles undergo systematic changes in size and shape, traveling as bed load or suspension load. Generally speaking, except in high latitudes and on steep coasts, little or no coarse bed load ever reaches the sea. Movement of the solid load down a river valley is irregular, both because the streamflow is irregular and because the transported material is liable to enter temporary storage, forming distinctive river-built features that range through riffles, midstream bars, point bars, floodplains, levees, alluvial fans, and river terraces. In one sense, such geomorphic features belong to the same series as deltas, estuary fills, and the terrestrial sediments of many inland basins.

Erosion process occurs on the river bed and the river banks. Erosion mostly occurs in the young stage of a river. This is because of high velocity of water. Its intensity is determined by some factors such as nature of the materials carried by water, the gradient of the land in which the river is flowing on and the nature of the bed rock. Rivers having salt bed rock erode by solution method. This takes place when the rock gets diluted in water forming solution.
