Spectral Wave Dissipation Over a Roughness‐Varying Barrier Reef

Frictional wave dissipation on a remarkably rough reef

We present a week of observations of wave dissipation on the south forereef of Palmyra Atoll. Using wave measurements made in 6.2m and 11.2m of water offshore of the surf zone, we computed energy fluxes and near-bottom velocity. Equating the divergence of the shoreward energy flux to its dissipation by bottom friction and parameterizating dissipation in terms of the root-mean-square velocity cu...

Spectral wave dissipation by submerged aquatic vegetation in a back- barrier estuary

Submerged aquatic vegetation is generally thought to attenuate waves, but this interaction remains poorly characterized in shallow-water field settings with locally generated wind waves. Better quantification of wave–vegetation interaction can provide insight to morphodynamic changes in a variety of environments and also is relevant to the planning of nature-based coastal protection measures. T...

Spectral Cascade and Energy Dissipation in Kinetic Alfvén Wave Turbulence

Spectral cascade and energy dissipation of Alfven turbulence is studied using a massively parallel gyrokinetic particle simulation. The simulation observes a magnetic energy spectrum with a power law index of ”-5/3” in the long wavelength, which agrees with magnetohydrodynamic results in the inertial range. In the dissipation range, the simulation finds a spectral break point on the ion gyrorad...

Experimental and Numerical Studies on Wave Breaking Characteristics over a Fringing Reef under Monochromatic Wave Conditions

Fringing reefs play an important role in protecting the coastal area by inducing wave breaking and wave energy dissipation. However, modeling of wave transformation and energy dissipation on this topography is still difficult due to the unique structure. In the present study, two-dimensional laboratory experiments were conducted to investigate the cross-shore variations of wave transformation, ...
