Water is imperative for our survival. The oceans
cover three-fourths of Earth and 65 per cent of our body is
water. But this same life-sustaining water has the ability to
destroy us completely. As Floods |
Forces of Nature: Floods
But the Inuit people, like most other traditonal
communities around the world, are bound to their land. They prefer to
remain secluded from the rest of the global community. Since the 1970s
their leaders have been campaigning for greater rights and asserting
their territorial claims.
Meaning
Flood is the overflowing of water onto land that is normally dry. The
word is also applied to suggest the inflow of tide.
CAUSES
Tropical Storms
One of the most common causes of floods is heavy rainfall that comes
with tropical storms. Such storms are full of moisture as they form over
the warm waters of the tropics. When right
conditions form, these giant storms
come towards the land and cause heavy downpour. The streams and rivers
often cannot cope up with the increased precipitation and cause the
water to overflow or floods.
Hurricanes
Hurricanes often cause coastal flooding. Powerful winds create huge
waves that crash on beaches. Hurricanes can be destructive in
combination with high tide.
Monsoon
Monsoon rainfalls cause seasonal or periodic floods on many rivers. This
often forms an area known as the ‘floodplain’. Riverine floods occur
only in winter as a result of heavy rain in combination with melting of
snow and glaciers in spring.
Tsunamis
Long, low sea waves caused by volcanoes, landslides, earthquakes, or
explosions can also cause floods. These waves are Tsunamis.

Tsunamis are extremely dangerous because of their high speeds, and
deeper water means faster-travelling waves. When the sea floor is
several miles below, waves can travel more than 600 miles an hour! Wait!
This isn’t all. They slow down as they come close to shallow water, but
build in height. Some tsunamis can be 50 to 100 feet high
when they hit
the shore!
Tsunamis can travel thousands of miles without weakening. They can pass
through islands or coral reefs without stopping, but usually die or
bounce back after hitting a large land mass.
