Dublin Bay Case Study May 12, 2021 Coastal areas are highly dynamic environments that are subject to diverse pressures, both anthropogenic (e.g. urban development, fishing, habitat modification) and natural (e.g. storms, erosion, floods). These pressures result in intensive and frequent seafloor alterations that demand efficient monitoring methodologies for repetitive updating of the seafloor morphology and bathymetry. Bathymetric information is essential in many coastal aspects, including environmental, management, research and economic. Optical satellite data provides an efficient alternative to bathymetric derivation in shallow coastal waters (
