Question 5 0/1 point
When a dam is built on a stream, a reservoir forms behind the dam, and this temporarily
creates a new base level for the part of the stream above the reservoir. How does the
formation of a reservoir affect the stream where it enters the reservoir and what
happens to the sediment it was carrying?
The velocity of the water slows down as it enters the reservoir and the sediment
is deposited.
The discharge of the stream increases, causing erosion of the valley walls of the
stream as it enters the reservoir.
The velocity of the water speeds up as it enters the reservoir and the sediment is
deposited.
The discharge of the stream decreases, causing the sediment to deposit.
