Abstract:
An extensive array of bottom boundary layer instrumentation was deployed for the same duration as the modelling period, across a transect of the shoal. The instrument array mainly consisted of Acoustic Doppler Velocimeters (ADVs), PC-ADP, OBS and pressure sensors. Also, bottom sediment samples were collected for calibrating the OBS sensors. The model simulations were in excellent agreement with in situ observations obtained from two bottom boundary layer arrays deployed at the shoal. The model results were also validated using time series and spectral wave data collected from NDBC Buoy 42035. It was found that the shoal could significantly dissipate storm waves during propagation across the shoal. The OBS data also showed that, during high energetic winter storm events, bottom sediments were resuspended and transported in various directions as a function of veering wind/wave fields.
