Modelling Impacts of Future Climate on Physical Susceptibility to Erosion: A Geospatial Approach Applied for the Coastal Area of Bangladesh
Publication: World Environmental and Water Resources Congress 2018: International Perspectives, History and Heritage, Emerging Technologies, and Student Papers
ABSTRACT
This research is an endeavour to generate future physical susceptibility to erosion under SRES A1B business-as-usual scenario of future climate for the entire coastal area of Bangladesh. This study employed geographical information system (GIS) based spatial raster model namely, coastal erosion susceptibility for Bangladesh (CESB) by employing future projections of climate-induced drivers. The outputs are justified through integrating experts’ opinions by developing fuzzy cognitive maps (FCMs). This study identified a total 276.33 km2 of land as high and very high susceptible to erosion for overall baseline condition (2015) that would be increased to 453.81 km2, 648.63 km2, and 1019.13 km2 by 2020, 2050, and 2080 respectively. This study also addressed seasonal variations of future climate in the assessment. This research might be seminal for coastal managers, policy makers, and researchers in managing future coastal lands in the area studied.
