Question

Quizplus · Accepted Answer

Structural control measures such as levees and dams can create a false sense of security and lead to development on floodplains, which can increase flood damage in the long run. When floods occur, the development on the floodplain can act as obstacles and increase the velocity of floodwaters, causing more damage. Therefore, encouraging development on floodplains can have adverse effects on flood mitigation efforts.
