As a result of climate change and global warming, polar ice is melting. Because of this melting, many lands are at the mercy of rising sea levels. Studies show that the mean sea level may rise by 0.16 to 0.63 metres before 2050, and 0.2 to 2.5 metres by 2100. In general, lower-lying islands are more likely to be close to the sea level, and that means these islands are particularly susceptible to sea level rise (SLR) risks. One of these islands is Failka, a small island in Kuwait lying in the entrance of Kuwait Bay, which is located on the north-western side of the Arabian Gulf. Most of Failka is less than three metres above sea level. The governmental plans are to develop the islands, which will be a very complicated issue. This study focuses particularly on detecting the areas of Failka Island which are under threat from sea level rise using Geoinformatics. Through spatial analysis of the SRTM DEM, three scenarios were calculated (1, 2 and 3 metres of SLR). These scenarios find that 31% of the island may disappear if the SLR is 1 metre; 54% could be underwater if the SLR is 2 metres; and 87% may disappear if the SLR is 3 metres. Coastal Vulnerability Index (CVI) was computed too. The CVI shows that the eastern coast is the most susceptible coast with regard to SLR. The model was calibrated through geostatistical analysis. Ground elevation points (n = 40) were extracted from the GPS altitude to show the model’s accuracy. The correlation was positive, where the was 0.8019. This study shows the importance of GIS and RS to help decision-makers in their future planning.
