CROSS-SHORE MOMENTUM FLUX DUE TO SHEAR INSTABILITIES

Ad Reniers, Jurjen A. Battjes

Abstract


Results obtained from a laboratory experiment on shear instabilities in wavedriven longshore currents were used to analyse the cross-shore structure of the shear instability induced momentum flux. As the shear instabilities grew in the downstream direction, a significant cross-shore momentum flux occurred. However, the expected changes in the mean longshore current velocity profile were not observed.
