Question

The reservoir behind a dam traps sediment that flows down the river, leading to the gradual accumulation of sediment in the reservoir. This is a well-documented effect of dam construction, as the natural flow of sediment is interrupted, causing it to settle in the reservoir instead of continuing downstream.
