This study focused on mapping possible flood-susceptibility areas in Pirojpur, Bangladesh using SRTM elevation data and GIS by combining four flood-influencing factors: elevation, slope, topographic wetness index (TWI) and drainage density. The results showed that the district is mostly under medium-risk (27%) of flooding, however, all of the sub-districts have areas that fall under the high (26% total of the district) to very high-risk (24% total of the district). To reduce the impact on society, it is essential to be prepared for natural hazards. The approach taken in this study will be helpful to the local authorities and the policymakers in assisting in making effective flood mitigation strategies and reducing the threats associated with floods.
