Flood
Flood (Flood) a relatively high flow of water, natural or artificial banks of the river which crosses are racing. Water flooded the plains surrounding the arrow beyond the suffering of the people, because usually becomes. The desirable and farming in the floodplains, flood control, so as not to exceed the limits in order to keep the loss of what is important to notice.
Every year, about 26000 sq km area that is 18 percent of the land is flooded. More than 55 percent of the entire territory of the country, flooding in heavily flood severity, he said. An average of the three major river in the wet season from May to October, 844.000 million cubic meters of water flow. This is 95 percent of the total annual flow. At the same time, compared to 187.000 million cubic meters of river flow is produced within the country due to rain.
Individual definition of floods in Bangladesh. During the rainy season the rivers, canals, marshes, wetlands and low-lying areas beyond the town and swept away crops, houses, roads, damages of possessions, he is called flooding. There is a relationship with the crop in terms of flooding. Flood-affected village
In Bangladesh, the floods can be divided into three categories -
A) seasonal floods (monsoon flood) - The seasonal floods, the rivers of water and decreases slowly
Flooded vast areas of the extensive damage to life and property;
B) flash floods (flash flood) - sudden heavy rain during a short hill slope or from
Or a natural or man-made dam break occurred; And
C) tidal flooding (tidal flood): The flood height with short duration, usually 3 to 6
Meter is up and locked into the drainage territory.
Ganges, Brahmaputra and Meghna rivers combined annual flooding of the Lower Meghna river flow through a single outlet in the Bay of Bengal. For this reason, the slope of the Lower Meghna and a reduced ability to emerge. The adverse effect of the height of the water level in the country.
Both the state and the ability to emerge by the flood waters controlled. The small river flow decreases and the surface of the water to rise above flood abhikarsika emerge only limited ground. Challenges emerge due to the floods in northern and eastern upland and mountainous regions of the country except the prevailing almost everywhere.
The north-western region of the Teesta and Brahmaputra flood control embankment on the right is saved plabanabhumiguloke. Plabanabhumisamuhake
northeast can be divided into 3 distinct areas, namely, Padma and Brahmaputra floodplains left; Madhupur by the Brahmaputra and the Meghna river basins separated from the Old Brahmaputra river valley.
Meghna basin Sylhet high-low (Great Sylhet Depression) is greatly influenced by the assumed name of the Surma and Kushiara Meghna rivers meet.
Padma Meghna river water downstream during high water levels are controlled by flooding. At the start of the rainy season in the Meghna river flood water quickly filled, and until the end of the rainy purnabasthatei exists. This rate is lower basin eme
What causes flooding
The factors responsible for flooding are: 1) In general, the lower the height of the topography on which the river flows. These rivers and their branches and tributaries of the dense reticulate eliminate built-paced ii) within the country and outside the country, heavy rains upstream in the rivers;
3) The Himalayan snow melting in the mountains and glaciers move naturally occurrence;
4) As a result of accumulation of silt in the rivers are filled to the bottom / side of the river to be occupied /
landslide occurrence;
5) The increase in the water together, and one of the major rivers of the impact on the other;
6) on the nature of human interference;
7) as a result of tidal and wind retro action to slow the flow of the rivers seafront (back water effect);
8) in response to changes in sea level;
9) tectonic disorder (earthquakes, changes in river flows and bhurupatattbe);
10) In response, including possible greenhouse.
Flood History
The country's history is inextricably linked with the history of flooding in Bangladesh. About half a dozen of the Bengal delta is facing a flood every century, byapakataya catastrophic flood in 1988, which is almost equal. This seasonal natural disasters in Bangladesh, the Mahabharata, the Ramayana and the other is written in the book. Chandragupta Maurya (E 321296 AD) during the reign of his
economics minister Kautilya's rainfall figures are mentioned in several places in the state to ensure that the accounts of precipitation was their idea. Varahamihira astronomer (507-587 AD E) could predict rain. Astronomer Aryabhata and Brahmagupta have studied the rainy season. Kalidas sanskrtakabi written in the rainy season and rtusanhara birahabhisara Meghdoot
world-dhrapadi-epic poetry. In ancient times, a gifted woman named khana but most of the weather and the forecast has krsibarta. His works still remember the peasantry. With the monsoon season in India's trade with the Arabs to change the knowledge productively utilized. The word derives from the Arabic word mausima season, which means season. Bengal floods that took place from 1870 until 1922 made the first detailed report of Professor PC mahalanabish has shown that, on average medium-sized floods once every two years and an average of 6/7 floods occurred once a year.
The repeated occurrence of a flood event. From 1787 to 1830, the old course of the repeated flooding of the Brahmaputra changed. In 1922 one of the devastating
floods in northern Bangladesh after a flood committee was formed. From 1922 until 1870, also north of the flooding in 1927 a report was published. Statistical analysis of the data obtained revealed that, like, seven years to the massive flooding and flood mahapralayankari once every 33-50 years, this town could inflict.

Flood-management
Flood control and dam projects emissions, polders and gravity is greatly dependent on the conductor. Structured approach to flood management and the over-dependence of roads, highways, railways and other infrastructure services such as water flow obstruction, which, in many cases, their impact on the flood situation was more serious. Despite the huge amount of investment in flood control projects and the emission results are not satisfactory in this case.
The devastating floods of 1987 and 1988 because of widespread destruction, suffering and loss of life. Two years after the flood, the government repeated a long-term comprehensive and lasting solution to the flooding problems in planning for the novice is to get out. To this end, several important surveys were conducted, which resulted in a flood prevention plan in 1989 (FAP) is made.
In Bangladesh, the number of flood control and flood damage reduction is proposed. Most of these proposals, however, centered on the Ganges, the Brahmaputra river in flood season, emissions more than the Ganges. Bangladesh floods from the settlements, and 130,000 hectares of farmland every year to protect the flood control dam at the rate of (mostly polder) strategy to build a following. Profit from the advantages of better security have been highlighted. Although the long-term assessment of the environmental impact has not been properly.
And the adverse impact of flood damage reduction and extra water to use for irrigation in Bangladesh Water Development Board has made a number of dams and canals were dug. Prominent among them are: G-K (GK) Project, Dhaka-Narayanganj-Demra (dienadi) project, Karnafuli multipurpose project, coastal dam project, in the northern wells project, Brahmaputra dams, irrigation projects Chandpur, Meghna-dhanagoda Project, Manu river project, Khowai river project, Pabna irrigation project, Gomti project, dill dam project, the Teesta barrage project (Phase 1), Dhaka Integrated flood control project, via Rehabilitation project, the implementation of urgent projects.
In addition to these structural measures for flood mitigation and loss reduction strategy as an alternative to non-structural measures need to be considered seriously. Non-structural measures to deal with the flood of social orientation is meant. These include: (1) to a safe place quickly so that people can take considerable time before the rising waters of the flood forecasting and warning process to the public is greatly strengthened; (Ii) fulfillment of Land Management to reduce water overflowing rivers. Punarbanayanera forestry and integrated program for the purpose of proper conservation
and the reduction of the adsorption process by increasing the height of the water may occur; (3) changes in land use and proper application of the building code, as well as diversification of crop production, flood or flood-resistant crops sahanaksama identification and adaptation of plant and crop planting season; (4) plabanabhumisamuhake divided into different zones to control land use and development activities to create the zone. Non-structural measures can be implemented at low cost.
Since the flood management an integral part of the overall water resource management, water and ecosystems, sustainable utilization of regional cooperation as essential to ensure that will help create a favorable atmosphere for joint techniques.
Every year, about 26000 sq km area that is 18 percent of the land is flooded. More than 55 percent of the entire territory of the country, flooding in heavily flood severity, he said. An average of the three major river in the wet season from May to October, 844.000 million cubic meters of water flow. This is 95 percent of the total annual flow.

Flood-management
Flood control and dam projects emissions, polders and gravity is greatly dependent on the conductor. Structured approach to flood management and the over-dependence of roads, highways, railways and other infrastructure services such as water flow obstruction, which, in many cases, their impact on the flood situation was more serious. Despite the huge amount of investment in flood control projects and the emission results are not satisfactory in this case.
The devastating floods of 1987 and 1988 because of widespread destruction, suffering and loss of life. Two years after the flood, the government repeated a long-term comprehensive and lasting solution to the flooding problems in planning for the novice is to get out. To this end, several important surveys were conducted, which resulted in a flood prevention plan in 1989 (FAP) is made.
In Bangladesh, the number of flood control and flood damage reduction is proposed. Most of these proposals, however, centered on the Ganges, the Brahmaputra river in flood season, emissions more than the Ganges. Bangladesh floods from the settlements, and 130,000 hectares of farmland every year to protect the flood control dam at the rate of (mostly polder) strategy to build a following. Profit from the advantages of better security have been highlighted. Although the long-term assessment of the environmental impact has not been properly.
And the adverse impact of flood damage reduction and extra water to use for irrigation in Bangladesh Water Development Board has made a number of dams and canals were dug. Prominent among them are: G-K (GK) Project, Dhaka-Narayanganj-Demra (dienadi) project, Karnafuli multipurpose project, coastal dam project, in the northern wells project, Brahmaputra dams, irrigation projects Chandpur, Meghna-dhanagoda Project, Manu river project, Khowai river project, Pabna irrigation project, Gomti project, dill dam project, the Teesta barrage project (Phase 1), Dhaka Integrated flood control project, via Rehabilitation project, the implementation of urgent projects.
In addition to these structural measures for flood mitigation and loss reduction strategy as an alternative to non-structural measures need to be considered seriously. Non-structural measures to deal with the flood of social orientation is meant. These include: (1) to a safe place quickly so that people can take considerable time before the rising waters of the flood forecasting and warning process to the public is greatly strengthened; (Ii) fulfillment of Land Management to reduce water overflowing rivers. Punarbanayanera forestry and integrated program for the purpose of proper conservation
and the reduction of the adsorption process by increasing the height of the water may occur; (3) changes in land use and proper application of the building code, as well as diversification of crop production, flood or flood-resistant crops sahanaksama identification and adaptation of plant and crop planting season; (4) plabanabhumisamuhake divided into different zones to control land use and development activities to create the zone. Non-structural measures can be implemented at low cost.
Since the flood management an integral part of the overall water resource management, water and ecosystems, sustainable utilization of regional cooperation as essential to ensure that will help create a favorable atmosphere for joint techniques.

July-August 1987, a major flood disaster. Damaged area of approximately 57.300 sq km (more than 40% of the country area). Such floods occurred in another 30-70 years. Inside and outside the country, was the main cause of excess rainwater flooding. West of the Brahmaputra, the Ganges-Brahmaputra region of the merger, Khulna ultaransa Meghalaya hills and adjacent areas were flooded.
Terrible flood disaster in August-September 1988. Damaged area of about 82000 sq km (more than 60% of the country area). Such flooding occurs annually 50-100. Rainfall and at the same time (within three days), the country's three major rivers flow occurs at the same time (muhapayatraharuba) occurs as a result of the extent of flood waters. The capital city is flooded. The flood lasted 15 to 0 days.
1989 Sylhet, Bogra and Moulvibazar 6 million people marooned by floods in the area.
In 1993, severe rains across the country thousands of hectares of crops were submerged. A total of 8 districts were flooded.
In 1998, more than two-thirds of the country's area is flooded for more than two months. This is comparable with the 1988 floods, according to the extent of the flooding. Heavy rainfall, which occurred at the same time the country's three major rivers and the flooding occurred due to a back eyaphektera water.
000 flood-ravaged districts of the south-western border of Bangladesh 5. Grhahlina nearly 30 million people. West Bengal, India earthen dam broke due to flooding.
Flood-management
Flood control and dam projects emissions, polders and gravity is greatly dependent on the conductor. Structured approach to flood management and the over-dependence of roads, highways, railways and other infrastructure services such as water flow obstruction, which, in many cases, their impact on the flood situation was more serious. Despite the huge amount of investment in flood control projects and the emission results are not satisfactory in this case.
The devastating floods of 1987 and 1988 because of widespread destruction, suffering and loss of life. Two years after the flood, the government repeated a long-term comprehensive and lasting solution to the flooding problems in planning for the novice is to get out. To this end, several important surveys were conducted, which resulted in a flood prevention plan in 1989 (FAP) is made.
In Bangladesh, the number of flood control and flood damage reduction is proposed. Most of these proposals, however, centered on the Ganges, the Brahmaputra river in flood season, emissions more than the Ganges. Bangladesh floods from the settlements, and 130,000 hectares of farmland every year to protect the flood control dam at the rate of (mostly polder) strategy to build a following. Profit from the advantages of better security have been highlighted. Although the long-term assessment of the environmental impact has not been properly.
And the adverse impact of flood damage reduction and extra water to use for irrigation in Bangladesh Water Development Board has made a number of dams and canals were dug. Prominent among them are: G-K (GK) Project, Dhaka-Narayanganj-Demra (dienadi) project, Karnafuli multipurpose project, coastal dam project, in the northern wells project, Brahmaputra dams, irrigation projects Chandpur, Meghna-dhanagoda Project, Manu river project, Khowai river project, Pabna irrigation project, Gomti project, dill dam project, the Teesta barrage project (Phase 1), Dhaka Integrated flood control project, via Rehabilitation project, the implementation of urgent projects.
In addition to these structural measures for flood mitigation and loss reduction strategy as an alternative to non-structural measures need to be considered seriously. Non-structural measures to deal with the flood of social orientation is meant. These include: (1) to a safe place quickly so that people can take considerable time before the rising waters of the flood forecasting and warning process to the public is greatly strengthened; (Ii) fulfillment of Land Management to reduce water overflowing rivers. Punarbanayanera forestry and integrated program for the purpose of proper conservation
and the reduction of the adsorption process by increasing the height of the water may occur; (3) changes in land use and proper application of the building code, as well as diversification of crop production, flood or flood-resistant crops sahanaksama identification and adaptation of plant and crop planting season; (4) plabanabhumisamuhake divided into different zones to control land use and development activities to create the zone. Non-structural measures can be implemented at low cost.
Since the flood management an integral part of the overall water resource management, water and ecosystems, sustainable utilization of regional cooperation as essential to ensure that will help create a favorable atmosphere for joint techniques.
Every year, about 26000 sq km area that is 18 percent of the land is flooded. More than 55 percent of the entire territory of the country, flooding in heavily flood severity, he said. An average of the three major river in the wet season from May to October, 844.000 million cubic meters of water flow. This is 95 percent of the total annual flow. At the same time, compared to 187.000 million cubic meters of river flow is produced within the country due to rain.
Individual definition of floods in Bangladesh. During the rainy season the rivers, canals, marshes, wetlands and low-lying areas beyond the town and swept away crops, houses, roads, damages of possessions, he is called flooding. There is a relationship with the crop in terms of flooding. Flood-affected village
In Bangladesh, the floods can be divided into three categories -
A) seasonal floods (monsoon flood) - The seasonal floods, the rivers of water and decreases slowly
Flooded vast areas of the extensive damage to life and property;
B) flash floods (flash flood) - sudden heavy rain during a short hill slope or from
Or a natural or man-made dam break occurred; And
C) tidal flooding (tidal flood): The flood height with short duration, usually 3 to 6
Meter is up and locked into the drainage territory.
Ganges, Brahmaputra and Meghna rivers combined annual flooding of the Lower Meghna river flow through a single outlet in the Bay of Bengal. For this reason, the slope of the Lower Meghna and a reduced ability to emerge. The adverse effect of the height of the water level in the country.
Both the state and the ability to emerge by the flood waters controlled. The small river flow decreases and the surface of the water to rise above flood abhikarsika emerge only limited ground. Challenges emerge due to the floods in northern and eastern upland and mountainous regions of the country except the prevailing almost everywhere.
The north-western region of the Teesta and Brahmaputra flood control embankment on the right is saved plabanabhumiguloke. Plabanabhumisamuhake
northeast can be divided into 3 distinct areas, namely, Padma and Brahmaputra floodplains left; Madhupur by the Brahmaputra and the Meghna river basins separated from the Old Brahmaputra river valley.
Meghna basin Sylhet high-low (Great Sylhet Depression) is greatly influenced by the assumed name of the Surma and Kushiara Meghna rivers meet.
Padma Meghna river water downstream during high water levels are controlled by flooding. At the start of the rainy season in the Meghna river flood water quickly filled, and until the end of the rainy purnabasthatei exists. This rate is lower basin eme
The country's history is inextricably linked with the history of flooding in Bangladesh. About half a dozen of the Bengal delta is facing a flood every century, byapakataya catastrophic flood in 1988, which is almost equal. This seasonal natural disasters in Bangladesh, the Mahabharata, the Ramayana and the other is written in the book. Chandragupta Maurya (E 321296 AD) during the reign of his
economics minister Kautilya's rainfall figures are mentioned in several places in the state to ensure that the accounts of precipitation was their idea. Varahamihira astronomer (507-587 AD E) could predict rain. Astronomer Aryabhata and Brahmagupta have studied the rainy season. Kalidas sanskrtakabi written in the rainy season and rtusanhara birahabhisara Meghdoot
world-dhrapadi-epic poetry. In ancient times, a gifted woman named khana but most of the weather and the forecast has krsibarta. His works still remember the peasantry. With the monsoon season in India's trade with the Arabs to change the knowledge productively utilized. The word derives from the Arabic word mausima season, which means season. Bengal floods that took place from 1870 until 1922 made the first detailed report of Professor PC mahalanabish has shown that, on average medium-sized floods once every two years and an average of 6/7 floods occurred once a year.
The repeated occurrence of a flood event. From 1787 to 1830, the old course of the repeated flooding of the Brahmaputra changed. In 1922 one of the devastating
floods in northern Bangladesh after a flood committee was formed. From 1922 until 1870, also north of the flooding in 1927 a report was published. Statistical analysis of the data obtained revealed that, like, seven years to the massive flooding and flood mahapralayankari once every 33-50 years, this town could inflict.
