Excessive supplies of water from
natural source say rains result into flood. This excess volume of water goes
into rivers and hence river bed swells and water overflows all over. This
overflow of water is called “Flood”.
Water thus enters farms, villages,
towns and cities. This situation is called “Flood Situation.” When water floods
over the farms the crops are badly damaged or ruined. When crops are ruined the food supply is
affected and the situation of a “Famine” occurs.
When water gushes into villages,
towns and cities with a violent current, it results into collapse of houses,
buildings and many other establishments. Numerous human and animal lives may be
lost by floods.
Floods
give rise to tremendous pollution. The dead animals and human bodies get
decomposed and spread foul smell everywhere. This atmosphere pollution results
into spread of several diseases like typhoid fever,
cholera, leptospirosis and hepatitis A and Vector-borne diseases, such as
malaria, dengue and dengue hemorrhagic fever, yellow fever, and West Nile
Fever. After the floods the government has a herculean task of cleaning
affected areas and rehabilitation of the occupants of such areas.
Floods normally
have the worst effect on the villages and localities near the river banks and
coastal areas. Hence government with the help of Army, Police and Air service
try and evacuate population from such areas and shift people to safe areas.
In nutshell
flood is a natural calamity that is disastrous. We can’t prevent the floods but
we can surely minimize them by our efforts towards (1) Saving Jungles (2)
Avoiding making catchment areas in colonies (3) Proper waste disposal and (4)
Growing more and more trees and creating green belts.
