- The river’s kinetic energy (or the energy that comes from the moving of the water as it flows downhill) is what causes the majority of the erosion to the geography of the river. Water moving past and over rocks, dirt, and other materials erodes them and often sweeps them along to be deposited further downstream.

Erosion also breaks up the rocks that are carried by the river. There are four types of erosion: Hydraulic action - This is the sheer power of the water as it smashes against the river banks.
Deposition. Test yourself. Overview - Erosion. Rivers can reshape the landscape through processes of erosion and the transport and deposition of materials. Erosion involves the wearing away of...
Aug 2, 2023 · How do geology and soil affect river regimes? Rocks allowing water to permeate them contribute to groundwater accumulation, slowly seeping into rivers as base flow. Soils with high compaction tend to have less infiltration and increased surface runoff.
Aug 22, 2023 · Geology: Softer, loosely packed rocks, like sand and gravel, erode more readily. pH: The more acidic the water, the faster materials dissolve. Human Impact: Activities like deforestation and constructing dams and bridges disrupt the river’s natural course, often leading to heightened erosion.
There are four main processes of erosion that occur in rivers. These are: hydraulic action; abrasion / corrasion; attrition; and. corrosion. Hydraulic action. The pressure of water breaks away rock particles from the river bed and banks. The force of the water hits river banks and then pushes water into cracks.
River rocks tend to be smooth and round because of a combination of the geologic processes of erosion and weathering. Rocks are eroded from surrounding areas and are initially rough and jagged, but over many years they are weathered via transport-induced abrasion to become smooth and rounded.
