Detailed explanation-1: -Monsoons cause the majority of flooding in India and China. What are monsoons? A monsoon is a seasonal change in the direction of the strongest winds of a region. Monsoons cause wet and dry seasons.
Detailed explanation-2: -While climate change is causing heavier downpours, the rapid growth of cities further exacerbates flooding by covering up surfaces that could otherwise absorb rain water.
Detailed explanation-3: -Tree root systems hold the soil together to slow the rate of flooding and reduce erosion. Trees themselves also absorb water during the rainy season. When the trees are removed from the environment, the rainy season can have devastating effects. Rains wash away the vital topsoil and what nutrients are left.
Detailed explanation-4: -The rivers a bring heavy sediment load from catchments. These, coupled with inadequate carrying capacity of rivers are responsible for causing floods, drainage congestion and erosion of river-banks. Cyclones, cyclonic circulations and cloud bursts cause flash floods and lead to huge losses.
