Dangers and Destructions of Floods and Hurri kindleesFloods and hurri basises have been effecting the lives of people aroundthe worldly concern for years. This research paper is going to state some of the worstfloods and hurri fag endes, and how early ones can be controlled.A flood is an overflow of water on dry land. The two types of floods be coastal and river floods. coastal floods are the branch topic in thisresearch paper.A coastal flood is the fill up of beaches and surrounding areasincluding bar spits and deltas. They can be effected by tidal waves and coastalcurrents. Coastal floods can cover a large aggregate of distance along a shore. Thelength of time a coastal flood is dangerous is usually very(prenominal) short. It depends onhow laid-back the soar upwards is which goes up and down twice a day. When the velocities ofhurricane winds become severe the natural elevation of the waves become three or more feethigher than the previous high tide. Coastal floods can be caused by a number ofthings. Coastal floods can be caused by runoff, hurricane waves, tsunami(seismic sea waves), and hurricane rains. Coastal flooding can not only takepart on oceans but it can also take part on lakes. Coastal flooding can be agreat danger because coast lines are very densely populated areas. In the UnitedStates in the early 1990s 50% of the population was on a coastal county.1Although they shrink before range shore, wind generated waves have beenspotted to be as high as 30 m (100 ft) in the middle of the ocean.2 In 1970 a study storm in the Bay of Bengal produced heavy seas that flooded regions ofEast Pakistan, sidesplitting about 200,000 people.3River flooding can happen a number of ways. The causes are rain,snowmelt, and ice jams. Soil can not absorb as more water with continuosmoistening. The longer that precipitation lasts the more water flows intostreams as runoff. waterspout floods only last for a couple hours, but they needa large amount of rainfall. Th is usually only happens in mountainous areas. Theyare called flash floods. Floods occurring from snowmelt and ice jams do not haveto be preceded by heavy rains. Moderate amounts of rain can make things evenworsened because the ground does not absorb it. Floods can result in the troubledams, aqueducts, weirs, landfills, paving, construction, and storm sewers. Theyare artificial causes.In 1993 when rainfall lasted from April until July in Iowa, Illinois,Minnesota, Missouri, Wisconsin, in the south Dakota, Nebraska, and Kansas, it coveredabout 16 one thousand thousand acres.4 Many deaths and $10 billion in damage was the result
