SATELLITE DERIVED BATHYMETRY FOR MONITORING NEARSHORE DYNAMICS

Research on the physical, ecological, and environmental processes in coastal zone traditionally rely availability of accurate seafloor topography (bathymetry) information. This information becomes increasingly important as environments are under pressure by climate change anthropogenic developments. Nonetheless, bathymetry shallow nearshore waters is only marginally monitored cost- time-intensive survey techniques that dependent in-field conditions. Here, Satellite Derived Bathymetry (SDB) offers a valuable alternative to enrich available bathymetric data both sparse rich environments, reducing need for in-situ measurements future. The high spatial temporal resolution satellite imagery yields more comprehensive understanding our coast its dynamics. Yet, consistently mapping still challenging, majority currently empirical SDB algorithms heavily calibration purposes. In this study we present methodology assessing horizontal morphodynamics using uncalibrated reflectance signal from sensors while focusing Friese Zeegat, tidal inlet Dutch Wadden Sea.
