WAVE DEFORMATION IN VEGETATION FRINGED CHANNELS

摘要

Vegetation flourishing along estuarine banks attenuates the incident waves, through momentum exchange between stagnated water mass in the vegetated area and rapid water mass in the central area. This study develops an analytical model for describing the wave attenuation rate in an assumed simple condition. A numerical model, which can be applied to more general conditions, is also developed. Based on both the analytical and numerical results, the physical properties of the wave attenuation are examined under various wave, geometric and vegetation conditions. Through comparisons between the analytical and numerical results, the usefulness and limitations of the analytical model are clarified.
