Rip Channels and Nearshore Circulation
Results from an experimental investigation into the e ects of rip channels on the nearshore circulation system are presented The results show that periodic channels in an otherwise longshore uniform bar induce longshore pressure gradi ents that drive pairs of counter rotating circulation cells Dense measurements of wave height wave setup and induced currents are presented In addition ev idence ...
متن کاملObservations of nearshore circulation: Alongshore uniformity
[1] Nearshore circulation, observed for 4 months on a 200-m-long stretch of natural beach during the SandyDuck field experiment, is shown to be alongshore uniform. An alongshore momentum balance between (wind and wave) forcing and bottom stress, cross-shore integrated between the shoreline and approximately 4 m water depth, holds on each of five instrumented cross-shore transects (skill 0.87). ...
متن کاملQuasi-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 کاملCurrents connecting communities: nearshore community similarity and ocean circulation.
Understanding the mechanisms that create spatial heterogeneity in species distributions is fundamental to ecology. For nearshore marine systems, most species have a pelagic larval stage where dispersal is strongly influenced by patterns of ocean circulation. Concomitantly, nearshore habitats and the local environment are also influenced by ocean circulation. Because of the shared dependence on ...
متن کاملAssimilation of Observations into Coastal and Nearshore Circulation Models
OBJECTIVES Develop an assimilation capability for fields of surface currents from Doppler radar systems. Continue the investigation and testing of an assimilation capability for surface wave effects. Use observations of coastal and shelf parameters to determine spatial decorrelation scales. Ascertain changes in these scales when determined from fields from prognostic simulations of a fine-scale...
