| Question | Answer |
| Location | Bangladesh is located in Asia on the coast of Bay of Bengal of the Indian Ocean. It shares borders with India and Burma |
| Severe Flooding | A severe flood occurred on October 4th 1998 which falls into the Monsoon Season. The main River Ganges overflowed |
| Why Bangladesh? | As there was torrential rain due to the monsoon season, heavy rain saturated the ground so the only way in which water could travel was by surface run off · 80% of Bangladesh is a floodplain as it has many rivers (less than 200m above sea level) · Deforestation in Nepal and Tibet in the north of the country caused a higher risk of flooding because there was no interception – therefore there was no water storage in trees and water flowed over ground · Lots of main river tributaries increased flood risk because with a small network of rivers, water had a limited area of where it could flow · The Himalayan mountains, being the highest mountain region in the surrounding area of Bangladesh meant that during spring snow-melt of the mountains, water flowed into Bangladesh as it acts as a drainage basin for a large area · River silt build up meant that the bed of the river rose. The capacity of the river was therefore made smaller and large amounts of water could not be carried |
| Social Effects | Loss of lives and injuries requiring aid · Long term effects of rebuilding lives · The communities are disturbed so rely on each other – there may be social break ups and tensions because of not sharing food and resources · Deaths: 918 · No schools or public services easily available |
| Environmental Effects | · Food and vegetation were destroyed as a result there was less food for families · Over 50% of crops were lost · 26500 cattle died · 5500 hectares of crops lost · Damages of habitats of animals as well as people · 15927 km of road was lost creating difficulty in transportation |
| Economic Effects | · Obvious loss of property and land so cheap prices. People abroad may take advantage of this and buy cheap land · Long term effect of less tourism effecting the money income of the country due to the unreliability of the weather · As within the environmental effects, the damage to crops was great so this gave a big impact on local farmers who had nothing to sell · Rebuilding the local area including roads, police stations, homes etc. requiring money |
| Solutions/Development for the future | There is instance aid from other countries, so Bangladesh can rely on the help of others · Building 7m embankments along the river channels will create a barrier and provide jobs for villagers but could increase number of mosquitoes carrying malaria · Emergency medical stores in each village providing essential drugs, dressings and water purification tablets reducing risk of disease spreading · Flood protection shelters can hold up to 1000 people and can be built on stilts. Animals can also go on saving both animals and people. These can however, be swept away · Widen/deepen the river · International flood plans and emergency flood alerts – flood warning systems · Building design – houses on stilts |
