Freshwater

A community near the Chesapeake Bay is experiencing increased flooding. As an environmental scientist, you are tasked with developing a plan to mitigate this issue. Which of the following strategies would be most effective in reducing the impact of stream processes and dynamics on flooding?

• Constructing more dams upstream to control water flow.

• Restoring wetlands to absorb excess water and reduce runoff.

• Building higher levees along the riverbanks.

• Increasing urban development to improve drainage systems.
