Abstract Signatures of rip currents can be identified in SAR images and aerial photographs of the near-shore. An area on the Portuguese West coast (bathymetry and wave climate of which are briefly described) was studied. An image corresponding to low wind speed conditions is shown, where a series of rip-like cell features are consistent with rip current morphology. A simple model is presented to explain the signatures, based on wind contrast due to the relative water motion within rip currents. The model is discussed for near-threshold wind conditions of Bragg wave excitation. All data in the Integrated Marine Information System (IMIS) is subject to the VLIZ privacy policy  Top | Author
