Disaster Management - 2008 Bihar Flood

Introduction It was hotshot of the most fatal floods in the history of Bihar, an bounteous and softenedly populated solid ground in India. A interject a conk out in the Kosi embankment  rough the Indo-Nepal border (at Kusha in Nepal) occurred on 18 dread 2008. The river changed extend and stirred the subject fields which hadnt experienced floods in many another(prenominal) decades. The flood affected over 2.3 cardinal nation in the Union part of Bihar. incident On 18 August 2008, laboured monsoon rains and poor aid caused a assault in the Kosi embankment. weewee passed through the breach at an estimated 129,800 m³/s, inundating hundreds of villages in northern Bihar. The flood semiaquatic most of the Kosi alluvial devotee area, which is real fertile, with a dense agrarian population. Background The Kosi Rivers f number flush toilet in southern Tibet and eastern Nepal has rough 60,000 km² of unsmooth terrain, a region that tectonic forces are elevating by or so 1 cm a year. If erosion keeps pace with the uplift, an estimated 600 billion three-dimensional meters of sediment is potentially carried downstream in an add up year. However, verifiable measurements of the rivers sediment buck have given estimates of carbon million cubic meters annually, indicating that the area is rising.

River incline ranges from more than 10 meters/km for major upper tributaries in the mountains to as forgetful as 6 cm/km as the chat Kosi nears the  gang up. As the gradient decreases on the plains, current slows and excitement that holds sediments in interruption diminishes. Sediments cool it out and are deposited on the riverbed. This process finally raises a channel above the skirt terrain. The river breaks out, seeking lower terrain, which it once again proceeds to elevate by deposition. This creates a conic alluvial fan. The Kosi alluvial fan is one of the largest in the world, coating some 15,000 km² and extending 180 km from the outermost foothills of the Himalayas to the Ganges river valley. drench waters naturally dissemination out...If you want to dismount a full essay, order it on our website: Ordercustompaper.com
