Abstract

This paper compares results from a simple numerical simulation of small-scale oil slick advection and spread (based on an equation of species coupled with wave-induced currents) with laboratory test data from a 3.5 x 6.0 m wave basin containing a sinusoidal beach profile. Dyed cedar wood oil provided clear visualizations of the experimental oil slick for analysis using a digital image processor. The numerical model predicted reasonably the nearshore circulation patterns and the movement of the oil slick. Even so, important discrepancies occurred, due to reflections from the experimental beach and the effect of surface tension-viscous spreading which were not included in the mathematical formulation. It should be noted that the small-scale results presented herein cannot be scaled up to prototype slicks that cover several surf zone widths.
