Why Is Flooding Prone To Bangladesh
Why is flooding prone to Bangladesh?
Bangladesh suffers from regular and extreme flooding for the following reasons, first being that its one meter above sea level, as well as it being a LEDC meaning it’s a less economical developed country. The rivers leading from the Himalayas flow into the sea, when they suffer with heavy rain the excess water starts to over flow and flood and waterlog land and surroundings.
The physical causes are, the monsoon climate brings very heavy rain and snow, and soils are leached and heavy runoff results in soil erosion, snow melting results in soil erosion and a rapid increase in river discharge. Moreover some more reasons are because deforestation in head water areas due to increasing population in Nepal and Tibet. Trees cleared for fuel and grazing land , less evaporation more runoff and faster soil corrosion, Rivers silt up due to increased soil erosion. This raises the river bed and reduces the capacity of the channel resulting in increased like hood of flooding ect….
Humans are making these circumstances worse by cutting down trees which erodes the soil because the rain disintegrates it apart or it runs off apart dragging along some of the soil into the river with it , which makes the river bed higher , which forces the water to erupt banks. Deforestation in Nepal and the Himalayas increases run off and add to deposition and flooding downstream. Development of the flood plain has increased greatness & frequency of floods. Global warming is blamed for sea level rise, increased snow melt & increased rainfall in the region. The building of dams in India has increased the problem of sedimentation in Bangladesh. Poorly maintained embankments (levees) leak & collapse in times of high discharge. Increasing population pressure in Bangladesh itself has resulted in the sinking of many new wells resulting in the lowering of the water table and the subsequent subsidence of land making it even more prone to flooding.
