Detailed explanation-1: -Erosion occurs on the outer bank or cut bank. Where velocity of the water on the inner bank decreases so do the competence and capacity. Deposition occurs, leading to the formation of a point bar. Over time, the position of the stream changes as the bend migrates in the direction of the cut bank.
Detailed explanation-2: -The faster the water is flowing, the larger the particles that can be kept in suspension and transported within the flowing water.
Detailed explanation-3: -When the stream velocity starts to decrease, larger sediments tend to settle out quicker than small sediments.
Detailed explanation-4: -Stream velocity, which increases as the volume of the water in the stream increases, determines the kinds of organisms that can live in the stream (some need fast-flowing areas; others need quiet pools). It also affects the amount of silt and sediment carried by the stream.
