Numerical hindcasts of storm flows and sedimentation during tropical cyclones in the western Gulf of Mexico, and a northeaster in the Middle Atlantic Bight, are summarized and compared. Physical causes of the differences in the hindcast flows and sedimentation are discussed. Circulation and sedimentation patterns are more uniform during the northeaster because the larger wind field associated with an extratropical cyclone matches regional coastal embayments better than the smaller, but more intense wind fields of tropical cyclones. Sedimentation is more variable during tropical cyclones and is more dependent on local coastal geometry and storm path.
