Jawaban:

1. What is the definition of flood?

Flood is an overflow of water that covers or soaks land. It can be caused by natural and human factors, including an overcapacity of a body of water, lack of vegetation, blocked sewage pipes and waterways, and heavy rain combined with melting snow.

2. What is the most common cause of flood?

The most common cause of flood is an overcapacity of a body of water, where soil and vegetation cannot absorb all the surface water and the excess water runs off the land.

3. What is a flash flood?

A flash flood is a flood that rises and falls rapidly with little or no advance warning.

4. How does the lack of vegetation contribute to flood?

The lack of vegetation contributes to flood because trees and vegetation absorb most of the surface water. When there are fewer trees, the soil alone cannot absorb all the water, causing the water to run off the land in quantities that cannot be carried in stream channels or kept in natural ponds or man-made reservoirs.

5. What are the different types of flood?

There are two main types of flood: periodic floods that occur naturally on many rivers, forming the flood plain; and flash floods that rise and fall rapidly with little or no advance warning.
