                     " FLOODS IN BANGLADESH "

The unusual swelling of water that overflows the banks of the rivers and submerges a vast area of land is called a flood. Bangladesh, being a land of rivers, often falls victim to floods almost every year. It is one of the most destructive natural  calamities in Bangladesh. Floods are caused for various reasons. Excessive and continuous heavy rainfall during the rainy season is the main cause of floods in our country. When there is heavy rain for days together, the rivers and canals can't hold and carry down so much water to the sea. As a result, the water overflows the banks of the rivers, canals and submerges vast surrounding areas. Heavy rush of water running down from the mountains sometimes causes floods. Floods are also caused by tidal bore accompanied by cyclonic storm. Floods create great damage to our life and properties. They sweep away our crops, cattle and houses and throw us into the grip of extreme distress. Thousands of people become homeless, helpless and suffer greatly for want of shelter, food and pure drinking water. Famine and pestilence break out in the wake of floods. People often drink dirty water. As a result various kinds of diseases such as choleras, diarrhoea, disentery etc. break out in the form of epidemic. The prices of all daily necessaries go up and people suffer greatly. Floods often do some good to us. During floods our rivers carry a great deal of silt that makes our soil alluvial and fertile. Floods wash away all sorts of rubbish and purify the surface of the earth. Though flood is a natural calamity in Bangladesh, yet it can be prevented by taking proper measures. By building dams and embankments across the rivers if water is distributed through canals, the calamities of flood can be reduced to some extent. Secondly, by dredging the river beds from time to time, occasional flood can be controlled. It is encouraging to note that the government of Bangladesh is fully aware of this problem and has already taken several measures to control it.
