Surface water floating materials cause significant negative environmental impacts. This study investigates, floating materials, size, distribution and rate of change, using remote sensing satellite data and debris detection indices. Sentinel-2 images captured at different times in the years, 2016, 2020 and, 2024 were used. Obhur Creek, digital images processed, detection models applied, histogram-based thresholding values obtained, and results binarized to identify and map the floating materials. Results demonstrated a multiscale distribution with continuous variations in size and shape. The yearly, rate of increase of materials size was 3.12%. This highlights a significant, issue that may lead to serious environmental negative impacts in Obhur Creek area in particular and the Red Sea coast in general.
