A study was conducted to determine overtopping rates for a step-faced seawall with curved parapet. The seawall was designed as part of a beach erosion control and hurricane protection project along approximately 6 miles of Virginia Beach, Virginia. Storm damages to the area have included loss of beach, destruction of bulkhead and seawall systems, damage to buildings, and inshore flooding along the commercially developed and urban shoreline. Using the Store Time-History Method developed for this study to calculate overtopping rates from results of physical model tests, results show that the design will reduce overtopping to a suitable level. The seawall design consists of a seawall with crest elevation of 15.7 ft NGVD fronted by a beach with elevation 3.4 ft NGVD which was testing using storm surge hydrographs from an August 1933 hurricane and a March 1962 extratropical storm.
