During a flood event, water flows out of its channel and onto the adjacent changing from a deep high-velocity channel to a shallow, broad, low- velocity channel. As water velocity at the edge of the deeper channel, courser-grained sediment deposit forming a natural .

Explanation:

Erosion can be defined as a geological process which typically involves the wearing out of earthen (soil) materials and the transportation of these materials by natural forces like water, wind, etc. Soil erosion is greatest when the soil is steep.

The steepness of a body such as river or stream refers to the downward slope or gradient of the body of water.

Generally, the steepness of a body affects the rate at which other materials would flow or move around. Thus, the steeper a river or stream, the greater would be its rate of erosion.

A flood can be defined as an overflow of a body of water in an area.

Generally, floods are caused by landslides, heavy rainfalls and soil erosion in an environment.

During a flood event, water flows out of its channel such as a drainage, dredged holes, etc., and onto the adjacent land changing from a deep high-velocity channel to a shallow, broad, low- velocity channel. As water velocity is deposited at the edge of the deeper channel, courser-grained sediment deposit forming a natural levee such as the steep bank of a river.
