Future sea-level rise projections for tide gauge locations in South Asia

Abstract Local projections of future sea-level change are important for understanding climate risks and informing coastal management decisions. Reliable relevant risk information is especially in South Asia, where large populations live low-lying areas at from inundation. We present a new set local selected tide gauge locations Asia. The used to explore the drivers spatial variations Asia over 21st century under RCP2.6 RCP8.5 scenarios. Global rise 2081–2100 projected be 0.39 m (0.26–0.58 m) 0.65 (0.47 m–0.93m) respectively. same period vary spatially region, with excess global equatorial Indian Ocean but less than northern Arabian Sea Bay Bengal. 0.44 (0.29–0.67 0.72 (0.51–1.06 Gan II (Maldives) respectively, whereas Diamond Harbour (West Bengal) corresponding changes 0.32 (0.19–0.51 0.57 (0.39–0.85m). find that sterodynamic contribution generally leading driver any single location, groundwater extraction sub-continent landmass main across region. localised quantify enhance potential feed into decisions planning by communities, government, industry.
