FLOOD IN BANGLADESH
Introduction:
Flood in natural calamity. It is relatively high flow of water that overtops
the natural or artificial banks in any of the reaches of a stream. Floods are
more or less a recurring phenomenon in Bangladesh. Almost every year, she
suffers from flood due to her geography.
Causes
of flood: There are several factors which cause flood in Bangladesh. These may
be classified into- 1) Natural causes and (2) Artificial causes. Natural causes
include the low topography of the country, heavy showers of rain, cyclones,
tidal bores and melting of snow on mountains. On the other hand, deforestation,
collapse of barrages and infrastructural lacunas are the examples of artificial
causes.
Damages
caused by flood: The have done by flood beggars description. It causes a heavy
loss to our life, property and crops. It sweeps over villages, roads and
fields. Each year about 18% of the country is flooded. During severe floods,
the affected area may exceed 55% of the total area of the country. Flood washes
away cattle and even people’s houses. Many human lives are lost, crisp are
damaged and trees are uprooted. All the communication system is suspended.
People become homeless and they take shelter on high roads, schools and
colleges.
After
effects of flood: The after effects of flood are more dangerous. Famine breaks
out in the flood affected areas. Many waterborne diseases like cholera,
dysentery etc. break out in an epidemic from. There is scarcity of drinking
water. the price of all daily necessaries goes up.
Advantages
of flood: There are positive aspects of flood too. It brings a great deal of
silt and makes our land fertile. It washes away accumulated filth from earth
and thus refreshes the environment.
Some
devastating floods in Bangladesh: The history of flood in Bangladesh is
inseparable from the history of this land. Every century she witnesses the
visit of a large number of intense floods. Among these, the floods of 1995,
1963, 1974, 1987, 1988, 1998 and 2004 were the most devastating.
The flood
in 1988 was unprecedented. It inundated about 67% of the total area. The flood
in 1998 was also very savage. More than 70% of the area of the country was
flooded and it lasted for more than two months. Than the flood in 2004 had
broken all former records. Over two thirds of the total area went under water.
The flood causes a total loss of 42 thousand crores taka. Last of all, the last
two consecutive floods in 2007 were also very terrible. Nearly 48 districts
were swept over by the floods. It took a heavy toll of lives. Many people
become homeless, many cattle died and huge properties were damaged.
Measures
to control flood: It is urgently necessary to take proper steps for the
prevention of flood in our country. Both long and short-term plans can be taken.
The silted-up beds of our rivers should be excavated for carrying more water.
Proper embankments should be constructed. Besides, a well planned irrigation
system will go a long way to reduce the extent and fury of flood. Moreover, an
efficient relief measure should be introduced promptly.
Conclusion:
Flood causes a huge loss to our country every year. So we must find out
effective and permanent measures for the prevention of flood. It is a matter of
hope that the Govt. has already initiated Flood Action Plan (FAP) and other
Flood control Drainage and Irrigation projects to control the depth of flooding
in our country.
