Shoaling internal solitary waves
[1] The evolution and breaking of internal solitary waves in a shallow upper layer as they approach a constant bottom slope is examined through laboratory experiments. The waves are launched in a two-layer fluid through the standard lock-release method. In most experiments, the wave amplitude is significantly larger than the depth of the shallow upper layer so that they are not well described b...
متن کاملGravity currents shoaling on a slope
Laboratory experiments are performed to examine gravity currents propagating into an ambient of uniformly decreasing depth. Predominantly, the study is of a surface gravity current shoaling over a bottom slope as it approaches a corner between the horizontal surface and the sloping topography. For sufficiently high Reynolds number currents, they are found to propagate at a constant speed over t...
متن کاملSubharmonic resonant excitation of edge waves by breaking surface waves
We have added a new Figure 3, where we show two frequency spectra. The first spectrum (Figure 3 a) is in absence of the breaking waves, where the first peak indicates the edge wave frequency and the second peak indicates the surface elevation frequency. The second frequency spectrum (Figure 3 b) is plotted in presence of breaking wave and indicates the suppression of the peak for the edge wave ...
متن کاملOn the Analysis of Dispersion Relation of Spatially Shoaling Waves
As waves propagate into nearshore waters, the wave dispersive relation is significantly affected by the nonlinear dynamics of the shoaling process (Herbers et al. 2002). This could have important effects to the interpretation and application of remote sensing results of shallow water waves (Stockdon and Holman, 2000). Many field studies are carried out based on temporally measured wave data to ...
متن کاملObservations of Polarity Reversal in Shoaling Nonlinear Internal Waves
Observations off the New Jersey coast document the shoaling of three groups of nonlinear internal waves of depression over 35 km across the shelf. Each wave group experienced changing background conditions along its shoreward transit. Despite different wave environments, a clear pattern emerges. Nearly symmetric waves propagating into shallow water develop an asymmetric shape; in the wave refer...
