| Abstract: | Motivated by the assumption that variations in the wave forcing field are the dominant factor in longshore variations in the nearshore circulation, a hybrid surf zone modeling approach has been developed. This approach combines high resolution 2-D wave generation and shoaling modeling with a simple surf zone circulation model based on 1-D momentum balances. Model-data comparisons are presented from two different field experiments performed in locations where the 1-D beach paradigm is not valid. As a rule of thumb, locations for model evaluation were chosen where the shoreline and shallow water isobaths, shows observable curvature over spatial scales on the order of the incident wavelength. The results indicate that the proposed methodology can be used to extend the range of applicability of the 1-D momentum balances but that it is not a general solution. |
