A flood is an overflow of water, an expanse of water submerging land, a torrent. Floods are most generally widespread of all relaxed disasters. They are also one of the most dodgy disasters as they bring enough might to change the whittle of land on Earth. They are one of the most costly weather connected disasters and are usually short lived events which ensue abruptly, with little caution. The total of flooding depends on the intensity of rain and the prolongation of the rainfall. Types of Floods:

1. River flooded: this is a purely stirring flood. Some are cyclic, happening only during a particular flavor; say frost or movement, when melting snow combines with leap rains, rich the canal valley with too much water, hence flooding the miles of land submit around it.

2. Coastal flood: These kinds of floods are caused due to the winds generated by intense low weight systems which steer ocean water internal causing intense flooding. Coastal floods are also caused by tsunamis, or tidal waves, which are fashioned by earthquakes. Beaches and coastal houses are swept away by the water causing intense destruction.

3. Urban food: Urbanisation causes what is called deforestation which includes conversion of fields and woodlands into commercial purposes, thus decreasing the water absorbing post of the land. This thing amplifies the scope of the floods and streets become prompt mirrors. The scratch cost is high in these types of floods as they arise in commercial areas.

4. Flash flood: It is the most risky font of floods as it is the fastest touching types and comes lacking counsel. It is an exclusive capture of flood that appears and moves swiftly across the land, catching people off lookout and unprepared .The causes of these types of floods involve highly concentrated rainfall, recurring thunderstorms or sultry storms. Dam failures coin the nastiest type of speed flooding as a large capacity for water is suddenly let supple downstream, destroying anything that obstructs its avenue. Water could ascend up to the height of 20 feet, shipping a massive quantity of fragments along with it.

5. Ice jam: Floating ice can accumulate at an artless or man-made obstruction and interrupt the spring of water.

Effects of floods: Soil erosion is one of the most prominent property of floods. The people affected by floods are cut off by the relax of the country and most means of exchange are disabled. The amount of food if insufficient can be the grounds of fatality after a flood occurs. Flood water destroys some granaries, fisheries and duration crops. Several roads are submerged in water. Floods can affect landslides and debris slides which are somewhat catastrophic in makeup.

Prevention of floods: Changing land use from farmland should be blocked. Construction of dams and levees moderate the expose of floods to a large extent.. Zoning restrictions check flood hurt. Governments should surpass laws preventing uncontrolled structure on flood plains to perimeter flood risks and to shelter adjoining property.
