Abstract:

A large scale collaborative field based research programme (B-BAND), aimed at measuring the small scale processes associated with nearshore dynamics on macro-tidal beaches, is currently underway in the UK. The instrument array utilises fast response sensors to obtain high resolution, synchronous measurements of water surface elevations (using 7 pressure transducers), horizontal current velocities (using 11 electromagnetic current meters), and suspended sediment concentrations (using 12 optical backscatter sensors). Preliminary results from a high energy dissipative beach (Llangennith, South Wales) emphasize the importance of infragravity oscillations to the nearshore hydrodynamics and sediment transport, particularly during storms.
