Abstract:
Field data were applied to derive a dynamical-based forecast model for rip currents on beaches. Breaking waves on beaches can produce high surf conditions as well as beach erosion. The interaction of waves and sea bottom may result in a rip channel in the surf zone. Moderate waves may drive strong rips off the shore which are dangerous to beach goers. Using field data obtained at Daytona Beach, we will demonstrate tools for predicting rip current using a regression analysis and a wave power scheme. The tool considers wave and tide effects and is capable of predicting rip currents with reasonable skill.
