Dangers and Destructions of Floods and Hurricanes
Floods and hurricanes have been effecting the lives of people around the world
for years. This research paper is going to state some of the worst floods and hurricanes,
and how future ones can be controlled.
A flood is an overflow of water on dry land. The two types of floods are coastal
and river floods. Coastal floods are the first topic in this research paper.
A coastal flood is the flooding of beaches and surrounding areas; including bar
spits and deltas. They can be effected by tidal waves and coastal currents. Coastal floods
can cover a large amount of distance along a shore. The length of time a coastal flood is
dangerous is usually very short. It depends on how high the tide is which goes up and
down twice a day. When the velocities of hurricane winds become severe the height of
the waves become three or more feet higher than the previous high tide.
can be caused by a number of things. Coastal floods can be caused by runoff, hurricane
waves, tsunami (seismic sea waves), and hurricane rains. Coastal flooding can not only
take part on oceans but it can also take part on lakes. Coastal flooding can be a great
danger because coast lines are very densely populated areas. In the United States in the
early 1990's 50% of the population was on a coastal county.1 Although they shrink before
reaching shore, wind generated waves have been spotted to be as high as 30 m (100 ft) in
the middle of the ocean.2 In 1970 a major storm in the Bay of Bengal produced heavy
seas that flooded regions of East Pakistan, killing about 200,000 people.3
River flooding can happen a number of ways. The causes are...
