Scaling surf zone turbulence
[1] Turbulence in the surf zone, the shallow region adjacent to the shoreline, has a key role in beach erosion, fertilization, dispersal, and larval settlement of marine invertebrates, and microbial contamination dilution in beach waters. Breakingwave generated (the dominant source) surf zone turbulence is understood poorly. A new surf zone turbulent dissipation rate scaling is derived, that co...
متن کاملComments on some recent measurements of anomalously steep and 03 tracer spectra in the stratospheric surf zone
Recent aircraft measurements, primarily in the extratropics, of the horizontal variance of nitrous oxide (N90] and ozone (O• in the middle stratosnho, ro, indicate that horizontal spectra of the tracer variance scale nearly as k -2, where k is the spatial wavenumber along the aircraft flight track [$trahan and Mahlman, 1994; Bacmeister et al., 1996]. This spectral scaling has been regarded as i...
متن کاملWave Group Forcing of Low Frequency Surf Zone Motion
The nearshore potential vorticity balance of Bowen and Holman (1989) is expanded to include the forcing from wave group-induced radiation stresses. Model results suggest that the forcing from these radiation stresses can drive oscillations in the longshore current that have a spatial structure similar to linear shear instabilities of the longshore current. In addition, the forced response is ne...
متن کاملGeneralized Set of Boussinesq equations for surf zone region
In this report, generalized wave breaking equations are developed using three dimensional fully nonlinear extended Boussinesq equations to encompass rotational dynamics in wave breaking zone. The derivation for vorticity distributions are developed from Reynold based stress equations.
متن کاملVortical surf zone velocity fluctuations with 0(10) min period
[1] Observations of velocity fluctuations with periods between about 4 and 30 min, thus longer than infragravity waves and referred to as very low frequency (VLF) surf zone motions, are described and compared with numerical simulations. The VLF motions discussed here exclude instabilities (generated by the wave‐driven alongshore current velocity shear) that occur in the same frequency range by ...
