Evaluation of Berm Shape for Wave Energy Reduction in Restored Tidal Wetlands
This study assesses the effectiveness of linear berms versus circular mounds to reduce wave height for wetland restoration. The Hamilton Wetlands are modeled using the phase-average spectral wave model STWAVE. The model is first validated with field data. The model results show that the berms are approximately twice as effective in attenuating the wave height as circular mounds of approximately the same volume. The presence of vegetation on the berms and mounds increases wave attenuation as long as the water depth is sufficient to submerge the vegetation. Because the circular mounds have more vegetated area, the vegetation induces greater additional attenuation for the mounds than the berms. Berms provide a longer extent of high crest elevations for the same volume of sediment compared to mounds, so are in general more effective in attenuating waves.
