Introduction: Bangladesh is a river delta plain delta region. About 250 rivers, large and small, surround the country like a net. Due to its geographical location, Bangladesh often faces various natural disasters. The flood is one of them. Like the lack of misery and poverty, floods seem to have become a daily occurrence for the people of this country. The people of this country have to fight with floods almost every year. The country's large rivers flood almost every year with mountainous rainfall and the Himalayan ice melt, making the lives of innocent people miserable.
Chronology of floods: Floods are a curse for Bangladesh. Almost every year floods cause loss of life and property to the people of this country. The major floods in the history of Bangladesh were in 1974, 1978, 1980, 198, 198, 1996, 2004 and 2006. The 1998 floods caused the most damage. The floods inundated most parts of the country. Many people died due to waterlogging. Many people die due to lack of food and various diseases. The floods caused by the cyclone in 2008 are the most recent catastrophe. The floods have caused severe damage in almost all parts of the country, including coastal areas. In 2013, monsoon floods occurred in some districts of northern Bangladesh. Millions of people were flooded. A total of 18 rivers, including the Padma, Meghna, Brahmaputra, Jamuna, Teesta and Dharla, overflowed the danger zone. The main cause of the flood is the excess water coming down from the upper reaches.
The severity of floods: Floods not only disrupt people's lives, but also the economy of the entire country. The various harmful effects of floods are described below-
- The number of low income people is more in Bangladesh. They eat day in and day out. Roads, farms and farms were submerged in the floods and their livelihoods were cut off. As a result, they live a dehumanized life due to lack of food.
- In flood prone areas, people's houses and agricultural lands are washed away by the floods. As a result, many people became landless. These landless people lose everything and travel towards the city. Involved in various anti-social activities.
- Bangladesh is a major agricultural country. A large part of the government's income comes from agriculture. But floods often disrupt crop production. As a result, the Bangladesh government suffered economically. Which affects the overall development of the country.
- Floods destroy various crops every year. This led to a food crisis. As a result, to meet the food demand of the country, food has to be imported from outside countries.
- Houses in low-lying areas are submerged during floods. People run houses or take shelter on high platforms to save their lives. They are afflicted with various ailments due to lack of proper drinking water and sewerage system. Even when the flood waters recede, there are outbreaks of various diseases.
- Floods also cause unpleasant situations in urban areas. The road sinks. Dirt came from the roadside drains. Various types of garbage decompose and cause bad smell. People's lives became miserable. In particular, the slum dwellers are suffering immensely.
Natural Causes of Floods: The natural causes of floods in Bangladesh are as follows-
Geographical structure: The geological structure of Bangladesh is the main cause of floods. Various rivers including Padma, Meghna and Jamuna have crossed Bangladesh horizontally and fallen into the Bay of Bengal. During the monsoon season, the water flow in the rivers increases and causes floods. Moreover, the southern edge of Bangladesh is less sloping. The depth of the rivers is decreasing every year due to siltation. It is not getting the opportunity to drain the excess water. As a result this excess water causes flooding.
Extreme rainfall: The Bay of Bengal in the south of Bangladesh and the Himalayas in the north. Therefore, Bangladesh is a rainy region due to geo-natural reasons. There is a lot of rainfall here every year during the monsoon season. The result is flooding.
Sedimentary lowland flooding: Various types of beels, haors and reservoirs located in Bangladesh save excess water of large rivers. But their water holding capacity is decreasing day by day as they become narrower and filled with silt carried by the river. As a result, excess water spreads to the plains around the river, causing flooding
