Coastal Engineering Studies in Support of Virginia Beach, Virginia, Beach Erosion Control and Hurricane Protection Project. Report 1. Physical Model Tests of Irregular Wave Overtopping and Pressure Measurements
A two-dimensional physical model investigation was conducted at scales of 1:13 and 1:19 (model to prototype) to provide input for the design optimization of a seawall proposed for long-term storm protection at Virginia Beach. This was one of a number of tasks conducted in support of the detailed design of a beach erosion control and hurricane protection project at Virginia Beach. The 2-D tests were conducted to acquire data on the expected rate of overtopping for two design storm types (hurricane and northeaster) at selected still-water levels, determine a stable stone size for a proposed fronting riprap berm, and to determine the distribution of wave-induced pressures on the face of the seawall. As a result of the 2-D tests, a stable stone size was determined for the proposed fronting berm, and overtopping rates were measured. An improved seawall design was recommended and showed a significant reduction of overtopping rates over the initial seawall design. Wave-induced shock pressures were recorded on the face of the seawall; however, durations were small and probably insignificant. Measured surge pressure magnitudes were relatively consistent and durations were significant. No significant negative pressures were recorded.
