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.

How can a town stop beach erosion without causing erosion in other places?

• build groins on the beach

• plant plants on beach dunes

• build seawalls along the shore

• remove buildings on the beach

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.
