A coupled hydrodynamic-bottom boundary layer model of storm and tidal flow in the Middle Atlantic Bight of North America

Abstract

The effects of increased friction and tides on circulation during the SWADE storm of 25-28 October 1990 have been investigated. The combination of downwelling offshore flow and tidal flow during the storm resulted in weaker bottom currents directed nearly alongshore during flood and stronger currents directed nearly offshore during ebb. Bottom shear stresses were initially highest when storm currents were largest and again later during ebb tides when tidal and storm bottom flows were in the same direction. These results suggest that sedimentation during the storm was directly related to the tidal flow. -from Authors
