6.Flood

Floods are one of the most common disasters to affect our lives. A flood is an overflow of water that submerges land. Flooding may result from the volume of water within a body of water, such as a river or lake, which overflows or breaks Levees, with the result that some of the water escapes its usual boundaries. Floods can also happen in rivers, when flow exeeds the capacity of the river channel, mostly at bends or meanders. Floods often cause damage to homes and businesses if they are placed in natural flood plains of rivers. while flood damage can be virtually eliminated by moving away from rivers and other bodies of water, since time out of mind, people have lived and worked by the water to seek sustence and capitaliz on the gains of cheap and easy travel and commerce by being near water. That humans continue to inhabit areas threatened by flood damage is evidence that the percieved value of living near the water exceeds the cost of repeated periodic flooding.

Floods can be prevented by placing sandbags and large rocks on riverbanks. A big amount rain would have to ocuur for flooding to happen.
