Verified by Toppr

Floods are common in north India because of excessive deforestation in the catchment areas. Roots of the trees keep the soil together and drain the extra water into the underground water reservoir. Due to deforestation (cutting down of the trees), the soil is no longer able to hold or drain the excess water thus leading to floods.
