abstract

  • Geo-referenced imagery and particle image velocimetry (PIV) are used to quantify surface flow fields in a laboratory wave basin. An application of the technique for topographically controlled rip currents is described. Exact comparisons between PIV data on an undulating free surface and groundtruth velocity data are difficult to perform owing to adverse effects of fixed objects in PIV imagery and the necessary placement of current meters below wave trough level. However, mean PIV velocity magnitudes compared favorably with acoustic Doppler current meter data from roughly 0.05 m below the still water level with root-mean-square differences of 0.077 ms-1 in the cross-shore and 0.059 ms-1 in the alongshore directions. © 2009 Begell House, Inc.
