Program and Agenda



The coupled surfzone and inner-shelf COAWST modeling system is used to simulate waves, circulation, and temperature on the inner-shelf and surfzone near Huntington Beach in the Southern California Bight during the Aug.-Oct. 2006 HB06 experiment. Observations include inner-shelf moorings in 8-30 m depth measuring temperature and velocity profiles, a wave buoy in 20 m depth, and seven nearshore tripods in 0.5-4 m depth measuring waves, velocity, and temperature. Here, the COAWST modeling system utilizes the coupled ROMS and SWAN models configured in a nested pattern for the inner shelf and surfzone. The outermost boundary information is given by a 75 m grid resolution simulation of the ROMS UCLA. Grid nesting follows a two-way refinement with coarsest grid resolution of 35 m, with subsequent intermediate and child grids with resolution of 12 and 4 m, respectively, resolving inner-shelf and surfzone processes. Model results are validated against bulk wave parameters, mean flows, and temperature. These results are then used to investigate mechanisms for cross-isobath exchange across the region.
