measured or hindcast wind speed and direction were included as surface wave forcing in
their respective applications.
Comparison at Westhampton. To assess the need for a fine-resolution grid in an area
where bottom contours are relatively straight and parallel, a comparison of the results at
Westhampton are presented in Figs. 8 and 9. The plots show a reasonable validation of the
regional STWAVE model (1 nautical mile grid resolution) with NDBC data as input. The
greatest directional discrepancies occur when wave energy is low.
