Project Description

Sandy Bay Infragravity Wave Project.

The dynamics of infragravity wave generation and propagation.

The study investigated (a) the processes governing IG wave generation and decay over the reef, and (b) the relative importance of IG waves, short waves and currents on the spatial distribution of bed shear stresses in the lee of the reef crest. A 3 week field study that consisted of an array of ten moored instruments was conducted to investigate the dynamics of low-frequency (infragravity) wave motions over a fringing reef.  A nearshore circulation model (XBeach) that includes IG wave generation, propagation and decay was then used to investigate the capability of numerical models to represent the hydrodynamic processes in a fringing reef environment.
