These types of losses are especially high in urban areas which will be possible to help relieve with correct planning and management with the urban set ups.

Geographical Information Systems (GIS) primarily based modeling and Remote Sensing (RS) methods can help by supplying roadmaps and methods as assist with make early on warning intended for risk areas. In this case study, different criteria have been assessed that have potential impact on how much devastation, like the elevation of the areas, water damage depth, building density, landscape slope, garden soil type, area use types etc .

Depending on different factors research, results are visualized with the help of GIS and RS presentation and dissemination approaches. In addition , the impacts of various factors about flooding by itself are also mentioned. Finally, a flood conjecture map pertaining to Dhaka Town Corporation (DCC) in Bangladesh was prepared using the Multi-Criteria Evaluation (MCE) method with particular give attention to the different criteria that influence the flooding in Dhaka city.

Normal water Logging:

Unplanned urbanization is raising water working.


The town can be significantly affected by earthquakes as it has happened during the past. Intensities of VI, VII, and VIII have already been signed up in the city. The countrywide building code of Bangladesh (BNBC 1993) includes 3 seismic areas and specific zones, and Dhaka is located within the second 1 with a housing code coefficient similar to the 15% of the the law of gravity (z=0. 15g).

According to the results of the Earthquake Disaster Risk Index (EDRI) project, main earthquake risk is associated with the high vulnerability of the building stock due to both poor materials and poor building processes.


The two transition periods among southwest and northeast monsoons over the American indian sub-continent are characterized by neighborhood severe hard storms. The transitional periods are generally referred to as pre-monsoon (March-May), and post-monsoon (October- November).
