We propose a method based on combining wave tracing and linear wave theory for the estimation of wave period and bathymetry in coastal areas from satellite images. The method depends on several parameters for which we provide ranges of variations adapted to the instrument. Experimental results are conducted on several sites located around the Hawaiian island of Oahu, using 13 Landsat-8 images. Results...
Wave-based estimation of coastal bathymetry from satellite images is challenging because it often implies relying on ancillary data. Moreover, spatial resolution remains coarse compared to the image resolution because state-of-the-art wave analysis techniques decompose images into large-size patches. The method proposed here is based on adaptive wave tracing where the patch size depends on the wavelength...
This article presents a thorough testing of the bathymetry estimation method known as Wave Kinematics Bathymetry. WKB is used with nautical radar and spaceborne optical imagery for shallow water zones [1], [2] and is based on the analysis of sea waves using two successive images of the same zone with an interval of only a few seconds. While in certain conditions the method seems to give promising...
