Determination of Tide Heights from Airborne Bathymetric Data

Abstract

Airborne bathymetric systems are currently under development. When fully developed, the NAVOCEANO plans to use this survey technology. NAVOCEANO faces a unique problem in using airborne bathymetry, in that it plans to survey in remote and undeveloped areas of the world where tide control obtained through tide gauge deployment is often logistically and economically prohibitive. This thesis offers a method for significantly reducing the number of tide gauges needed for tide control in such a survey when the survey is conducted in an open coast environment. The approach provides a method for delineating a tidal zone and then suggests a survey scenario which will allow the isolation of the major components of the tidal signal through a least squares adjustment. A proof of concept simulation model developed in the thesis results in tidal depth reducers which more than satisfy IHO specifications.
