Quasi-3D Nearshore Circulation Equations: a CL-Vortex Force Formulation
INTRODUCTION Recently much attention has been paid to different formulations of surface wave force in wave-driven ocean and coastal circulations (e.g., McWilliams et al., 2004, Mellor, 2003, Smith, 2006 and others). Basically, the analytical expressions for surface wave force and wave-current interaction can be classified into two types. One is the classical wave 'radiation stress' concept pres...
متن کاملNumerical modelling of induced rip currents by discontinuous submerged breakwaters
Submerged breakwaters are one of the shore protective structures. Any discontinuity in these breakwaters causes changes on current parameters including speed and water surface profile. In this paper, discontinuous submerged breakwaters were modelled to investigate the changes in the wave and flow pattern.To investigate the phenomenon, three models including a shore with constant slope, a shore ...
متن کاملEstimation of Nearshore Tidal Currents on Nonsmooth Continental Shelves
The theory of Battisti and Clarke (1982) to calculate analytically barotropic tidal currents across 'smooth' continental margin topography is shown to be valid near shore on 'nonsmooth' continental shelves. The theory includes longshore gradients and friction and produces formulae easily evaluated with coastal sea level data. The tidal currents across three such shelves (West Florida, south of ...
متن کاملRadar Measurement of Waves and Currents in the Nearshore Zone
The objectives of this effort are to determine the extent to which Doppler radar techniques can be exploited for both qualitative and quantitative nearshore measurement applications. Of particular interest are estimates of surf zone location, extent, surface currents, and wave parameters. To date, optical (video) techniques have been the primary remote sensing technology for these applications....
متن کاملModel for the Computation of Time-Steady Nearshore Currents
BACKGROUND: Under the assumptions of longshore uniformity, monochromatic and unidirectional waves, one-dimensional (1-D) models have predicted the steady depth-integrated longshore current with reasonable accuracy in the regions of intense breaking (e.g., Bowen 1969; Longuet-Higgins 1970; Kraus and Larsen 1991). The addition of random wave fields with directional spread (Battjes 1974; Thornton ...
