With part of the nearshore arrays in place, the time for GPS-tracked drifter measurements has come. Next week an extensive set of drifter deployments is planned to map the complex flow patterns at the tip (most seaward point) of the Sand Motor. Last Tuesday the Delft team performed trial deployments in order to get to know the system.
The tip of the Sand Motor is influenced by a complex mixture of strong tidal currents and wave-driven currents over a spatially highly variable bathymetry, making it quite different from the adjacent 'regular' beach. Furthermore, there might be tidal eddies forming as a result of flow separation on the northern side during flood and on the southern side during ebb currents.
