Space Technology and Geographic Information Systems Applications in adb projects

Contribution of Space Technology and Geographic Information Systems
The analyses of impacts of climate change scenarios on flooding, urban drainage, and salinity intrusion for 
Khulna were conceived based on dynamic mathematical modeling followed by the presentation of the results 
in GIS with the following data: (i) topographic data of the Khulna city area, rainfall of the Khulna region, water 
level, river discharge, salinity, and drainage data collected for the input of the three mathematical models; 
(ii) satellite image of high resolution (0.6 m, QuickBird) procured for updating the base map for Khulna and 
also to check the land use patterns; and (iii) other maps procured and collected mainly from Khulna City 
Corporation and Khulna Development Agency.
Results
The results from the climate model, the urban drainage model, and the socioeconomic and damage 
profile of the inhabitants from past experiences of disasters were used to estimate the cost of disasters 
for similar future events based on 2030 and 2050 climate scenarios. This information is now combined 
with a business-as-usual economic and social scenario for the future to determine the overall damage 
cost for Khulna.
