All these parameters were analyzed Geographic Information System (GIS) assigned weightage decision-making technique namely- Analytic Hierarchy Process (AHP). Finally, map was generated seven Upazilas district. Very high, moderate low identified after overlaying all indicator maps under consideration. 45.96% portion total 2115.2 sq. Km. Area very high highly final Jamalpur. Such type assessment process significant mitigation projects view providing greatest concern zones. can also help policymakers provide emergency aids other privileges those who are need it.
