What encourages flooding by allowing water to run off into streams?
expeople1 [14]

Deforestation encourages flooding by allowing water to run off into streams

<u>Explanation</u>:

Deforestation plays vital roles in the flooding. The roots of the Trees prevent sediment runoffs and forests hold more water than farms or grasslands.Firstly the leaves in the trees will capture some amounts of water which will be eventually evaporated. Secondly, some quantity of water is  absorbed by the tree's roots. Also,Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream..

The process of deforestation will lead to dislodging of the topsoil. this makes the  topsoil unstable and reduces its capacity to hold down the water
