WAVE AND CURRENT OBSERVATIONS IN A TIDAL INLET USING GPS DRIFTER BUOYS
The Wave Resolving Drifter (WRD) Buoy, developed at NPS, was refined by adding an accelerometer and utilizing horizontal Doppler velocity measurements to better resolve the wave surface motions. The WRD Buoy was validated against a Datawell Waverider-GPS buoy by comparing bulk wave statistics, wave …

The interaction of periodic surface gravity waves with slowly varying water currents
The governing equations for interactions between surface gravity wavetrains and slowly-varying water currents are derived and the incorporation of Vocoidal water wave theory into this framework is discussed. The emphasis throughout is on the derivation of the general form of the governing equations …

Cross-Shore Sediment Transport in Relation to Waves and Currents in a Groin Compartment
<p>In nearshore areas waves are generally irregular, and the irregular wave-induced currents have different peak velocities (magnitude asymmetry) and durations (duration asymmetry) between forward and backward motions. These asymmetries may produce a net cross-shore sediment transport in one …

Modelling waves and near-shore circulation around the Cape Peninsula: towards enhanced predictions for South African coastal activities
… with 700 m horizontal resolution to simulate waves and currents in this area. The model is driven by realistic forcing, striking a previously lacking balance between geographical coverage, spatial granularity, and process complexity. It has the potential to be deployed in forecast mode in …

Flow, sediment transport and bedforms under combined flows
… refers to a combination of unidirectional and wave-induced oscillatory flows, is omnipresent in natural environments and generates a range of bedforms on sandy beds. Combined-flow bedforms are abundant in coastal and lacustrine environments, as well as in their ancient counterparts in the rock …
