Abstract:
Goals and objectives include the following: a) To examine the dynamics of rip currents and the factors governing the evolution and magnitude of the cross-shore fluxes of sediment and water associated with rip cell circulation on a medium to high energy beach over a wide range of space and time scales. b) To examine the spatial and temporal variability of rip currents using remote video imaging techniques. c) To quantify changes in nearshore circulation and topography in response to varying incident wave conditions at different time scales including; wave groupiness (time scales of 1-10 min), tidal modulation (time scales of 12h and 24 h) and wave height fluctuations associated with passing weather systems (time scales of 2-5 days). d) To develop a coupled hydrodynamic and sediment transport model to simulate the coupling between the nearshore circulation forced by the incident wave field, and the nearshore topography. e) To advance current nearshore video imaging techniques using a high resolution digital camera system.
