“…Whereas depth estimates seaward of the breaker zone are accurate (Stockdon and Holman [7] report typical errors of 5% of the observed water depth), wave nonlinearities and the difference in optical signatures of breaking and nonbreaking waves cause depth estimates further onshore to be highly inaccurate. For instance, Stockdon and Holman [7] and Holland [12] show differences between estimated and observed depths of more than 1 m in depths 3-4 m. This is unfortunate, as it is within the breaker zone where spatial and temporal depth variations are largest, and accurate estimates are most urgently required.…”

“…In a geophysical setting, on an entirely different scale both in space (from several meters up to kilometers) and in time (frequencies lower than 1 Hz ), several different techniques are used to measure wave-fields, including radar (altimeter) measurements from ships (Senet et al, 2001) or even from satellites (Forbes et al, 1993;Stammer, 1997) and photographs of sea surface glint taken from aircraft (Dugan & Piotrowski, 2003), as well as measurements from in situ arrays of buoys and pressure transducers (Holland, 2001). …”

“…For freely propagating ocean waves, the wave number, wave frequency and water depth are not independent, but are linked by the wave dispersion relation [2,30]. If the effect of current can be neglected, the linear dispersion relation is given by:…”

“…Underwater features and ocean bathymetry is an indispensable information for coastal engineering and management and coastal resources exploitation and protection [1,2]. For example, safely navigating, offshore fishery and aquaculture, research on tide and biodiversity, planning for seawalls and wharf and other human activities are carried out in these areas where water depths less than 100 m. Detailed knowledge of water depth is very useful for them.…”
