Sentinel-2 Bathymetry Indicates River-Mouth Migration and Asymmetric Sediment Redistribution at Cua Dai, Vietnam
Satellite-derived bathymetry (SDB) can support monitoring of dynamic river mouths, but its interpretation depends on survey–image timing, validation design and spatially explicit uncertainty. This study applies an established Sentinel-2 blue–green log-ratio workflow to Cua Dai, Vietnam, using four archived image–echo-s...
