Active erosion takes place along the river course, causing weathered and eroded rock particles to travel downstream with the water. These sediments are trapped by the dam and deposit there, preventing areas below the dam from receiving any sediment. This is in turn affects deltas further downstream. Deltas are formed at river mouths if the load deposited exceeds the amount being eroded away by the sea. Since the sediments are trapped by the delta, the amount of sediment being deposited onto the delta is less than the amount being eroded away by the sea.
