Abstract
This study assesses coastal dynamics in the Tabounsou estuary, located south of Conakry, Guinea, over the 1975-2016 period. Landsat imagery was utilized through GIS and remote sensing approaches. Results reveal significant coastal retreat, with an average erosion rate of 13.14 m/year, and project its continuation at 8.35 m/year by 2036. Findings indicate a correlation between rising temperatures and intensified coastal retreat, highlighting the combined effects of climate change and local factors on the coastal environment. One key limitation lies in the study’s exclusive reliance on data from a single satellite imagery source, thereby excluding the integration of multi-source data that could have enabled more robust analysis and cross-validation of results.
