Floods are the most natural disasters that occurs in some parts of the country with near regular frequency. The Gangabrahmaputra plains are most prone to floods.
WHY FLOODS OCCUR
Floods are caused when the volume of water exceeds the normal carrying capacity of a river . During the rainy season, rain water flowing past small rivulets joins the main current . The volume of water flowing into the main current thus far exceeds the channel capacity. The excess water overflows the banks and spreads on the surrounding areas. Subsequently, floods also hamper the environment. It causes soil erosion and this degrades the quality of the soil .
Rain is not the only cause for flooding. Floods also takes place when a cyclone strikes a coast . Why rains are natural phenomenon, there are certain other factors that lead to flooding of rivers . A river flowing through a hilly region May be blocked due to a landside. In that case ,that water will flow into the neighbouring areas .
EFFECTS OF FLOODING
Floods cause immense damage to life and property . In August 2000, floods in the Northeast region killed 100 people. In Assam alone , around 70,000 people lost their homes . During floods, the affected regions are cut off from the rest of the country. The worst affected are the farmers and the economically backward communities and the farmers lose their crops . Furthermore, people face power cuts due to the danger of electrocution. They also have to face expensive pricing.
WAYS TO PREVENT FLOODS
The government and citizens must work together to formulate ways to prevent floods. Proper awareness must be spread about the steps when floods occur .In addition, areas that are more likely to have floods must have tall buildings above the flood level .
Further, there should be an efficient system for storing excessive water due to rain . This will prevent the overflowing of water. One of the most important steps is to strengthen the drainage system . This can avoid water logging which will prevent floods. Otherthan that , dams must be constructed strongly. The use of cheap materials causes dams to break. The government must ensure there is quality buildings of dams to prevent floods.
