Abstract

Coral reef islands are highly vulnerable to impacts of climate change and sea level rise. Information on
long-term shoreline changes in coral reef islands is critical for effective coastal management and response to climate
change and sea-level rise. However, such information is either unavailable or difficult to obtain, in particular for atoll
islands. There has been a growing awareness that remote sensing has the potential to provide more detailed information
for shoreline change modelling and assessment. This study presented ways to model the shoreline changes of coral reef
islands in the Maldivian Archipelago using satellite observation and cloud computing. Eight coral reef islands from
different atolls in the Maldives were selected for this study. Results show that the coral islands have undergone significant
shoreline changes. The long-term changes were attributed to erosion and land reclamation. The seasonal shifts were
caused by monsoon changes. The outcomes from this study contribute to knowledge for low-lying coral reef islands
management in response of climate change and sea level rise.
