Observational analysis highlights spatio-temporal turbidity variability in Lagos's Marina/Badagry Channel, indicating remote sensing as a reliable monitoring method.
Water turbidity, a critical parameter in aquatic ecosystem health, affects navigation, light penetration, and water quality. This study evaluates turbidity levels in part of the Marina/Badagry Channel, Lagos State, Nigeria, using satellite-based remote sensing techniques. Sentinel-2A multispectral imagery was employed to derive turbidity indicators through band ratios and reflectance modeling. In-situ turbidity measurements were used to calibrate and validate the satellite-derived estimates. The results revealed spatio-temporal variability in turbidity, with elevated levels concentrated around areas of high anthropogenic activity and low water flow. The integration of field and satellite data demonstrates the feasibility and accuracy of remote sensing for turbidity monitoring in dynamic coastal environments.
