Answer Details
The deposition along the channel of River Amy to the southwest is probably due to the fall in gradient at the base of the hill. When a river flows down a hill, it gains speed and erosive power due to the steep gradient. However, when it reaches the base of the hill, the gradient decreases, causing the river to lose some of its erosive power and deposit the sediment it carries along the way. This deposition process is more likely to occur on the inside of a meander or a bend in the river, as the water slows down and sediment accumulates.
