The Ganges and the Apparatus both had more than the normal amount of water that they could carry and so were overflowing and flooding. A number of human factors also contributed to the devastating flooding of Bangladesh, including large amounts of deforestation and overbearing. Deforestation for logging or farming removes trees that would otherwise absorb and delay the flow of rainwater.

This means that the maximum amount of surface water can travel down the hills and tributaries. In the long term a number of flood prevention measure are possible: the creation of embankments artificial levees along the river to increase channel capacity and restrict flood waters — however since7,km of flood embankments have been constructed and yet many were breached In the floods; constructing flood protection shelters large bulldogs raised above the ground to shelter both people and animals emergency flood warning systems and plans made for organizing rescue and relief services: providing emergency medical stores in villages building flood proof storage sheds for grain and other food supplies dam construction upstream and major embankments around Dacha have been suggested however lack of money has meant that these suggestions have not been taken further, bangladesh flooding case study.

Upon contact with the topographically vertical coast, these winds experienced a strong up- drafting force thus causing internal moisture to reach the atmosphere, and consequently cool as a string of storm clouds. With convergence and coalescence, enhanced moisture levels resulted in heavy rainfall on the afternoon of 16 August At he peak of the downpour, at about 1 GMT, In Obsolesce, 89 mm 3.

The rain was much localized: four of the nearest 10 bangladesh flooding case study gauges, all within a few miles of Obsolesce, showed less than 3 mm of rain that day.

It is estimated that 20, cubic meters 5. Xx US gal of water flowed through Obsolesce that day alone. The steep valley sides and the saturated surface ensured a high amount of surface run-off.

Changes in farming practice in the area also possibly contributed, sewage could have been a cause as well, bangladesh flooding case study, with a reduction of trees and hedges higher up the valley causing water to flow through more quickly than would have been the case in the past. Fortunately, no one died in the flood, bangladesh flooding case study. Impact of the bangladesh flooding case study 75 cars, 5 caravans, 6 buildings and several boats were washed into the sea; approximately homes and businesses were destroyed; trees were uprooted and debris were scattered over a large area.
