Answer 1

Afforestation

In many countries, rivers are prone to floods and are often carefully managed. Defenses such as levees, bunds, reservoirs, and weirs are used to prevent rivers from bursting their banks. ... They are designed to reduce potential flood levels by up to one metre.

Answer 2

Option(a) is the correct answer.

Afforestation

• When a large area is covered with water from a river or a sea, which should be dry it is called a flood.
• A flood can have natural as well as man-made causes. Areas near rivers and the sea are flood-prone. Heavy rainfall also causes floods.
• Afforestation means planting a large number of trees. Trees hold the land and provide a strong grip. When a flood occurs a large number of trees can resist them and hence reducing the damage.
