Give the outline of an river erosion
Answers
Answer:
Erosion is the process that wears away the river bed and banks. Erosion also breaks up the rocks that are carried by the river. ... Abrasion - When pebbles grind along the river bank and bed in a sand-papering effect. Attrition - When rocks that the river is carrying knock against each other.
Answer:
Rivers are dynamic structures. They change their inflow patterns continuously and naturally. These differences affect river bank soil stabilization as the river bank absorbs the energy. River bank corrosion is a part of this changing nature. When banks of a river wear down by watercourse, it's called river bank corrosion.
Substantially river banks are made of stratified layers with cohesive and cohesion accoutrements. The river banks have three zones:
Toe zone,
Bank zone and
Overbank area.
The Toe zone is positioned between the ordinary water position and low water position which makes it vulnerable to erosion.
However, vulnerability is increased, If non-cohesive accoutrements are at the toe zone.
But at the time of lowering water position, cohesive banks are most susceptible to corrosion because of their low water permeability.
