GENERAL GEOLOGY

Detailed explanation-1: -There is less water on the inside bend of a meander so friction causes the water to slow down, lose energy and deposit the material the river is carrying, creating a gentle slope. The build-up of deposited sediment is known as a slip-off slope (or sometimes river beach).

Detailed explanation-2: -On the inside of the bend, water movement is slower. Material builds up here due to deposition. This makes the bank gently sloping and the river channel shallow.

Detailed explanation-3: -In a meandering river, water will tend to flow fastest along the outside bend of a meander, and slowest on the inside bend.

Detailed explanation-4: -When rivers flood the velocity of water slows. As the result of this the river’s capacity to transport material is reduced and deposition occurs. This deposition leaves a layer of sediment across the whole floodplain.

Detailed explanation-5: -On the outside of the meander, the surface of the water has a tendency to be slightly higher, or super-elevated, because it has gained momentum and acceleration. Here, the flow is forced down the outer bank, which results in a steeper velocity gradient and greater bed shear stresses.
