Spatial landslide risk assessment in a highly populated Rohingya refugee settlement area of Cox’s Bazar, Bangladesh

<title>Abstract</title> In recent time, landslide has become the major concern in the southeast part of Bangladesh. The study aims to develop comprehensive landslide risk mapping by applying the analytical hierarchy process (AHP) and geospatial techniques in Ukhiya and Teknaf Upazilas (highly populated Rohingya Refugee Settlement area) located in the southeast part of Bangladesh. To assess the landslide risk, 12 influencing criteria of hazard, vulnerability and exposure such as precipitation intensity, landslide inventory, distance to fault line, stream density, distance to stream network, elevation, aspect, slope, geology, normalized difference vegetation index (NDVI), landuse-landcover (LULC), and population density have been selected under the relevant components of risk. The spatial criteria were weighted using AHP, and the weighted overlay techniques were used to…
