Abstract: Bangladesh is one of the most natural disaster prone areas in the World. The different types of disasters like flood, cyclonic storms, tidal surges, droughts, tornadoes, riverbank erosion, earthquake, etc. occur frequently in Bangladesh. Identifying the vulnerable areas with reference to natural hazards causing damage to the housing stock and the related infrastructure are most important for infrastructures development.
In this study, four natural hazards which are the most common for damaging in Bangladesh, namely earthquake, cyclones, tornadoes and floods are considered to develop the district wise map on the basis of combination of local hazard intensity and vulnerability on observed performance. Risk analysis as indicated in the district-wise are trying to be identified.
This study will find out the disaster prone areas of Bangladesh and also the damages, history, severity of these areas, intensities of those natural disasters and housing vulnerability. GIS based disaster database is very crucial and an important aspect for environmental management strategy for planning and disaster mitigation, preparedness and preventive actions. The information will assist the environmental management, different field of sciences such as engineering, agriculture, fisheries, and policy making and planning of Bangladesh and should be an integral part of the whole process of economic and social development in Bangladesh. The findings of this study would be beneficial for engineers and city planners. They constitute a fundamental means which should...
