Abstract:

The specific scientific objectives of this study, to be carried out in collaboration with the Tidal Flat investigators, are a To describe the geomorphologic changes using historical satellite imagery. b To improve our understanding of the dynamics of tidal flats during various phases of the tidal cycle using satellite SAR image data. c Support the on-going experimental measurement phases with new satellite data acquisitions. d To determine how SAR signatures can be related to the sedimentary and geotechnical properties of the tidal flat. e To generate high resolution wind maps for improved understanding of the wind forcing variability and turbulence over tidal flats. f To provide spatial snapshots of the dynamics during the flooding and ebbing stages governing tidal flats. g Radar imaging of the wave field and translation of the images into snapshots of elevation maps of the surface using both satellite and ship or floating platform based sensors. h Measurements of the wave field and the atmosphere above the wave field using ASIS buoys to generate data sets that could be compared to wave models and radar both in the spectral and phase-resolved domains, and leads to a better understanding how the wind profile, fluxes, coefficient of drag vary with respect to differing wind and wave conditions. i Measurements of breaking using acoustic and microwave means as well as in-situ sensors locally.
