The government of a flood-prone region wants to implement some measures to reduce the risk of floods, which method is likely to reduce the risk of
floods in that region?
a.
deforestation
b. construction of bridges in rivers
c. building concrete roads
d. preservation of wetlands

The correct answer is option D. "preservation of wetlands".

Explanation:

Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.
