“…By averaging over shorter wave time scales, clutter was removed leaving an image showing patterns of enhanced wave dissipation that have been shown to correspond well to submerged sand bar or shoreline features (Lippmann and Holman, 1989;Holman et al, 1993;Lippmann et al, 1993;Holland et al, 1997;Holland, 1998;Ruessink, 2003a, 2003b;Plant et al, 2007;Pearre and Puleo, 2009). Since imaging is low cost and can span large areas, time exposure imaging has offered an excellent tool for long-term studies and was the method selected here for exploring the details of ebb-tidal delta morphology.…”
