Floods and its Consequences
Floods occur when soil and vegetation cannot absorb all the water; water then runs off the land in quantities that cannot be carried in stream channels or retained in natural ponds or dams. This excess water causes flooding of plains.
Floods also occur naturally on many rivers, forming an area known as the flood plain. These river floods often result from heavy rain, sometimes combined with melting snow, which causes the rivers to overflow their banks.
Floods and Floods
Buildings are most affected by floods. Buildings constructed with mud and bricks get damaged easily. Thatched huts and small houses with tinned roofs also get damaged during floods.
People who occupy the flood plains of rivers are most affected by floods
As mentioned earlier, buildings are affected badly by floods.
- Small houses and huts get washed away in flood waters. These houses are totally destroyed in the flood waters.
- Houses which do not have a firm foundation get washed away or tend to float.
- Houses in low lying areas get inundated with water. There is great loss to property in this case.
- Flood waters can damage the foundation and walls of buildings and this will make the construction weak.
- Houses may get affected due to floating debris, like huge trees.
Damage to houses during flood has to be minimised. The first and foremost thing to be done is prevent inundation of flood waters.
People should avoid building houses on river banks or near the sea coast. Houses should be built at least 250 meters away from the river banks. The government should ensure proper drainage system.
Buildings should be built on an elevated platform. Buildings in flood prone areas can be built on stilts or columns.
