This cut communications and made rescue operations difficult. This seasonal flooding is beneficial as it provides water for the rice and jute two main crops in the area it also helps to keep the soil fertile. Auth with social network: Flood action plan — a system of huge embankments along the coast and rivers reinforced by concrete. Deaths were not only due to being swept away by the flood waters but also secondary effects of flooding, such as disease spread in contaminated waters and the lack of food resulting in starvation in some cases.
Monsoon rainfall — some parts of the Ganges basin receive mm of rainfall in a day during the monsoon. This mass of sediment is dumped in Bangladesh choking the river channels making them more inefficient and reducing hydraulic radius. The land is densely populated. Bangladesh is prone to serious and chronic flooding. Most of the land forms a delta from three main rivers – Ganges, Brahmaputra and Meghna – and 25 per cent of Bangladesh is less than 1 m above sea level. The main highway connecting Dhaka to the rest of the country was flooded isolating the capital.
A map of Bangladesh There are advantages to living here: A computer is a technology system. The low-lying land means it is easily flooded. Sfudy seasonal flooding is beneficial as it provides water for the rice and jute two main crops in the area it also helps to keep the soil fertile.
Deforestation of the Himalaya — reducing interception rates which means shorter lag time and higher peak discharges.
These would hold back peak flow, but the costs of construction are very high. Half the country is less than 6 m above sea level.
They disgorged water from seasonal wet monsoon rains and melting glaciers and snow in the Himalaya. Tectonic uplift of the Himalayas means that erosion rates of sediment increase as the rivers have more potential for erosion.
The Himalaya also forces relief or orographic rainfall, increasing rainfall totals and then river levels further.
In major flooding occurred across wider South Asia, affecting not only Bangladesh but parts of India, Bhutan and Pakistan. This hampered relief efforts. Published by Megan Leonard Modified over 3 years ago. Bridges were destroyed, the death toll rose to and the airport and major roads were flooded. To be able to explain how a specific riverine area has been managed.
Death — overpeople died in a cyclone and flood in the s. We think you have liked this presentation. More sustainable ways of reducing the flooding include building coastal flood shelters on stilts and early warning systems.
Water supplies were contaminated by dirty water and sewage and fresh water became scare. The monsoon flooding killed over 1, people in Bangladesh sourceand according to Forbes over people were killed across the South Asia region.
Major fishing villages will be affected and agricultural land and rice paddies will suffer the effects of salinisation. SPARSO and flood satellite imaging systems — allow more warning to be given to Bangladeshis by monitoring cloud cover, hydrographs and rainfall patterns across the river basins.
Effects of the floods Flood waters swept away and caused severe damage to railways, roads and bridges. Registration Forgot your password? There are disadvantages too: Weather Troubles In Different Countries.
LEDC Flood Case Study: Bangladesh
Cyclones from the Bay of Bengal cause and contribute to coastal flooding. Flooding is an annual event as the rivers burst their banks. Rice farmer in Bangladesh. The snowmelt in the Himalayas adds water into the main rivers.
Solutions Flood action plan — a system of huge embankments along the coast and rivers reinforced by concrete. Floods Hard and Soft Engineering. If sea levels rise Eustatically and Bangladesh sinks Isostatically because of the loading of sediment on the delta there will be major impacts on the bangladesj of Bangladesh.

The flat floodplains of the delta are very fertile. In September June the 30 th to 15 th of August heavy rain and rivers carrying water from upstream exacerbated flooding.
Bangladesh is prone to serious and chronic flooding.
