Measurement Techniques for Coastal Waves and Currents.

Abstract

A Towed Oceanographic Data Aquisition System (TODAS) consisting of a towed platform (sea sled) with current meters and a wave gage has been developed for collection of information on nearshore currents and waves. Data acquired by the sensors are telemetered to shore and digitally reocrded. TODAS is used for real-time evaluation of flow characteristics between shore and a depth of 9.14 meters (30 feet); this mobile battery-operated system can be used at remote locations. The system has been used principally in two experimental designs: (a) Monitoring the distribution of longshore currents in shore-normal profiles, and (b) a combination of Eulerian-Lagrangian experiments where fixed-point metering is supported by aerial photography of diffusing dye plumes and concentration measurements of the dye tracers.
