Landslide, Slope stability, Geo-hazard, Rainfall thresholdAbstract
This research is mainly focused on landslide hazards of the world’s largest refugee camp of Ukhiya, Cox’s Bazar Bangladesh. The whole area mainly small hillocks and hills of Ukhiya area are at great risk especially during monsoon. Several case studies result of recent slope failures is presented to understand the risk during monsoon in the camp area. From numerical seepage and stability modeling of slope at different locations of Ukhiya camps, it is established that Ukhiya hill slopes and the temporary shelters of Rohingyas are at great risk during monsoonal heavy rainfall for sustainable community-based living in the camp area. This study will ultimately help to manage hazards for sustainable hill management and settlement on hills. Based on the rainfall threshold (140 mm to 280 mm) line, warning system can be developed to save lives and properties of the camp inhabitants for further study.
