Question

Which of the following are measure(s) that are to be done before a flood strikes?
  1. Afforestation
  2. Deforestation
  3. Dam construction
  4. Embankment construction


Solution

The correct options are
A Afforestation
C Dam construction
D Embankment construction
Afforestation means planting trees on any land. Afforestation along the banks of the river or their catchment areas helps to reduce the runoff. Dams should be constructed across rivers to help contain the volume of the water in the river. Embankments should be built around water bodies to stop the water from flooding the surrounding areas.
