چکیده انگلیسی
Alongshore-directed water surface gradients âη/ây were measured along the feeder channel and around the ends of the inter-tidal bar, with head differences O(0.1 m). The numerical model reproduced âη/ây with a good level of skill and showed that âη/ây and ãuvã increase with the proportion of breaking waves Qb over the inter-tidal bar; but ãuvã was maximised during peak Qb, maximum âη/ây occurred when wave breaking moved offshore to the sub-tidal bar and Qb was reduced. Around low water, the forcing of the rip current by the alongshore pressure-driven feeder current was reduced by the decrease in Qb over the bar and feeder regions, but an offshore flow through the rip channel was maintained by a localised intensification of âη/ây around the ends of the inter-tidal bar.
