FINE-SCALE MEASUREMENT OF SEDIMENT SUSPENSION BY BREAKING WAVES AT SUPERTANK

Stephen F. Barkaszi, William R. Dally

Abstract


During the SUPERTANK data collection project, a mobile, vertical array of five Optical Backscatterance Sensors was used to measure sand suspension in the outer surf zone. Test conditions included both regular and random waves, and two different wave energy levels. Examination of the data reveals significant cross-shore variation in both the structure of the time-dependent concentration, as well as mean suspended load.
