Simulation study on detecting shallow bathymetry via wavelength

Abstract

Nearshore bathymetry is of vital significance to coastal environment and ocean engineering. Remotely sensing technologies are feasible and economical to detect nearshore bathymetry. Wave Spectrum Bathymetry (WSB) method based on the linear theory takes advantages of the remote sensing to obtain wavelength and leads to bathymetry. A simulation with FUNWAVE model over a plane slope and an elliptical shoal shows the WSB method can do well in different topographies. The mean relative error is less than 8% in the 5-12m depth range.
