A study was conducted to determine beach-fill berm dimensions in order to provide backshore areas with sufficient protection from storm-induced flooding. The beach-fill design was part of a beach erosion control and hurricane protection project along approximately 6 miles of Virginia Beach, Virginia. A modified Kriebel cross-shore numerical model was used to evaluate various berm dimensions for several hurricane and northeaster storm events. Results of the modeling effort indicated a 100-ft-wide berm with an elevation of 5.4 ft National Geodetic Vertical Datum would provide sufficient protection for the 100-yeastorm event. Grain size analysis of the native beach and seven borrow areas indicated that an overfill ratio of 1.37 was appropriate for the design. Applying this value, initial beachfill volumes were calculated in addition to 2- and 5-year advanced nourishment quantities.
