What are some effects of building a dam?
A) a stream has more sediment below the dam and so can erode more efficiently
B) the reservoir lake) traps sediment that over time fills up part of the reservoir
C) a dam, whether constructed by nature or by humans, represents a permanent change in base level
D) the stream erodes into the land instead of depositing sediment, where it enters the reservoir
Dam
A structure built across a river or stream to hold back water for purposes such as storage, flood defense, or electricity generation.
Sediment
Particles of rock, mineral, or organic materials that accumulate in layers on the Earth's surface, often transported by water, wind, or ice.
Base Level
The lowest point to which a stream or river can erode its channel, often sea level for rivers.
- Evaluate the influence of human-made structures such as dams on the environmental and geomorphological aspects of river systems.

Final Answer :
B
Explanation :
Building a dam results in the trapping of sediment in the reservoir lake, which over time can fill up part of the reservoir. This is because the natural flow of sediment downstream is blocked by the dam, causing sediment to accumulate in the reservoir area.
