Abstract

The present paper describes a 1-D depth inversion method to determine water depths from surface images using extended Boussinesq equations. Synthetic input data from a time-dependent Boussinesq model is used as input. A least squares method is used to estimate local wave phase speed from the time-lagged images. The inversion model predicts underlying water depths and water particle kinematics for various wave conditions to reasonable accuracy. For irregular wave conditions, the inversion results from several images have to be averaged to estimate the actual depth.
