Quantifying the Frequency With Which Visual Signatures in Time-Averaged Imagery Indicate the Location of a Rip Channel
Abstract
Video cameras were first introduced as a low-cost, logistically accessible nearshore sensor in the late1980s with the Argus system (Lippmann and Holman, 1989, 1990). Over the next 15 years, methods were developed that use these sensors to observe nearshore characteristics such as wave height (e.g.: Aarninkhof and Ruessink, 2004; Almar et al., 2012; Andriolo, 2019 and others), run-up (Holman and Guza, 1984; Simarroet al., 2015), celerity (Holland et al., 1991), and surface currents (Chickadel, 2003). Methods have also been developed to estimate locations of wave breaking from observations (e.g., Piotrowski and Dugan, 2002;Simarro et al., 2019; Stockdon and Holman, 2000; Thuan et al., 2019 and others). Today, video cameras remain a popular nearshore observation tool because they are relatively inexpensive and logistically simple to set up on site, and they can be used to observe a site continuously throughout daylight hours (Holman and Stanley, 2007).
