Using Hydrodynamic Models to Interpret Remote Sensing Images of the Sea Surface

Abstract

The long-term goals are to develop methodologies for determining beach topography in the nearshore, using various types of remotely-sensed images of the water surface as input. We are particularly interested in regions such as the surfzone, where linear theory provides a poor description of the behavior of individual wave crests. The objectives of the present project are to: (1) Develop a synthetic data set, based on Boussinesq model predictions, representing a number of cases of waves propagating over characteristic nearshore bathymetries. (2) Compare model results to available SandyDuck data. (3) Study the feasibility of solving the inverse problem for bathymetry from measured surface data, using a wave model to determine wave phase speeds and wave-induced height and velocity fields.
