WebA longshore current is a net movement that occurs as waves intersect the shoreline at non-perpendicular angles. Sand stirred up by waves in the surf zone is thus moved along the shore by longshore drift. Refraction process refers to the wave refraction as it changes direction of a travelling wave as it moves over the differing depths of ocean.

WebA rip current is another type of current that develops in the nearshore area and has the effect of returning water that has been pushed up to the shore by incoming waves. If part of a beach does not have a strong unidirectional longshore current, the rip currents may be fed by longshore currents going in both directions. (1) Figure 8.3.5. WebHow do rip currents form?
