Constructive and Destructive Forces Technology

How are dams and levees alike?

• Both control floods.

• Both control weathering.

• Both are natural barriers.

• Both prevent coastal erosion.

How do storm drains help prevent flooding?

• They act like levees.

• They move storm water to dams.

• They block storm water from streets and houses.

• They allow storm water to flow into nearby waterways.

A state builds a dam across a river. How will the dam MOST LIKELY affect the region?

• It will prevent flooding by blocking high waves.

• It will rebuild an eroded floodplain by trapping sediment.

• It will prevent flooding by controlling the flow of the river.
