A Fractal Model of Ocean Surface Superdiffusion

Abstract

The transport of surface pollutants in the coastal zone is modelled using a modified particle tracking diffusion model. The new model uses fractional Brownian motion (fBm) functions to produce superdiffusive spreading of the synthesized pollutant clouds. The model is tested on a numerical model of a coastal bay recirculation zone.
