what role do forest play in the prevention of floods
Answers
Forests play a major role in preventing and controlling floods. Tree stores water in its deep roots. So, Forests allow the water to go into the soil. They also prevent the extreme water run-off and hence prevents landslides & topsoil erosion. Most of the flooding disasters are caused by deforestation.
The volume of water retained by forests can depend on several characteristics such as forest cover area and tree density. A strong forest cover of 30-40% acts as a brake against flash floods and thus preventing enormous loss of lives & property, and reducing the damage from flooding.
Explanation: Forest plays an important role in the prevention of floods
- Forests play a vital role in the contribution to food security.
- They maintain correct environmental conditions required for agricultural production.
- They help in preventing soil erosion, maintain stabilizing of the soil, increase the capacity of land to store water and also maintain soil temperature and air.
- It absorbs rainwater naturally by allowing the water to seep beacuse of the roots present in the trees.
- Raindrops which fall on leaves gets evaporated into the air as a result very little quantum of water reaches the ground.
- This prevents the rainwater to hit the ground directly which then prevents from soil erosion.
- Soil erosion leads to flood as the soil tends to lose its capability to absorb or hold the water. Thus forests prevents from soil erosion
- Trees present in the forest helps in slowing down the flow of running water and prevents floods.
