Question
Explain how, deforestation leads to frequent flooding of rivers.

Answer

Deforestation plays several roles in the flooding equation Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream. However in the absence of trees, soil is loosened, and it gets washed away easily with water or torrential rains and is deposited into river. When rivers have soil and water level more than their holding capacity, it lead to over flooding and causes floods.
