Dr. Emma Nuss has published her paper in JGR: Oceans! Using FUNWAVE-TVD simulations of transient rip currents on a barred beach, Emma found that the bar enhances both the generation of vorticity and the eddy-eddy interactions that lead to transient rip currents. The overall effect is that an increased directionally spread wave field does not always increase the transient rip current activity. Yikes! Some modifications to our previously published relations are now in order. Check out the paper here.
