Bay of Bengal

Three rivers - the Ganges, the Brahmaputra-Jamuna and Meghna - merge in Bangladesh and flow into the Bay of Bengal.Bangladesh literally surrounded by India on all sides.The capital Dhaka this populous country associated with the area of ​​the delta major roads, but a message is often disturbed due to the monsoon.

On the territory of Bangladesh is one of the world's largest floodplain valleys, where three great rivers run up thousands of arms, making their way to the sea.Even Dhaka, the capital of the country in which they live six million people, rising above the sea level, only 8 m, and during monsoon, the water is often worth the waist.Bangladesh - startlingly green country, but the water that makes it such a fertile, produces and terrible destruction, from time to time falls on the land.

To the north of the country lie the Himalayas borders, and it was there, in the great snow-capped mountains, originate all these powerful river.Brahmaputra-Jamuna originates in Tibet and overcomes more than 289

0 km, while falling by about 4900 m, to merge into the Bay of Bengal.

Ganges long meanders through the territory of India before the break on a myriad of constantly changing its course to the arms of the bay, which is known as the Mouth of the Ganges.Meghna is inferior in size to other rivers, but it can cause tremendous destruction, when overflows.In 1991, only a small area of ​​Meghna washed 61m of land, taking homes, crops and animals.

Although about 4,000 km was constructed in Bangladesh.dams, trying to subdue the restive river remain largely ineffective.Melting snow in the Himalayas and Musoni rains raise the water level in the rivers, and every year they poured one-fifth of the country, washing away huge sods.But the water, destroying the fertile layer, the very same, and it creates.Together, the river deposited 2 billion tons of sludge per year, and as soon as some small islands of silt washed off immediately formed the other.Floods also increase fish stocks and throw the algae that feed the seedlings.

Plans to curb the Rivers, similar applications in the United States on the Mississippi, but Mississippi, leaving in July 1993, the banks in spite of all facilities, questioned their prospects.Spills of these rivers, especially the Brahma-Putra-Jamuna, turned into a huge torrent of muddy brown water, which many believe to invincible.Bangladesh - a poor country, and some questioned the wisdom of spending public funds for the construction of dams and dykes, - in fact, they may not only be useless during strong floods, but also inflict additional harm by changing the natural course of the river.

irrigation project Meghna-Dhonagoda, which cost $ 50 million, was designed to protect against flooding and erosion, more than 200 square kilometersfertile farmland.Despite the high dam, the river celebrations, and only one portion in 1979 was eroded by more than 1.5 km.Part of the problem lies in the speed with which the water is carried to the sea and partly in the speed with which it can be raised to the level of the river.

In humid and hot air, the Bay of Bengal there are powerful area of ​​low pressure, giving birth to some of the fiercest cyclones in the world.Over the past 30 years Bangladesh has fallen 16 cyclones, wind speed exceeded 120 one o'clock.Huge storm waves, driven by the wind, rushing inland, causing the path of death and destruction.Although in some areas are now built concrete shelter, the storm in April 1991 demonstrated the vulnerability of people and their land before the forces of nature.
