Solution

India is prone to large number of natural disasters. Heavy rainfall causes overflow of a large amount of water from rivers, streams, etc., beyond its normal limits causing floods.
Water running over land surface carries away loose material of soil and transports it downstream, this process is known as soil erosion. Every year billion tonnes of soil is eroded into oceans, seas and deep lakes.
Thus, rainfall which is more than optimum range result in floods and soil erosion.
