|Title:||Nearshore Sticky Waters|
|Seminar:||CCMA Luncheon Seminar|
|Speaker:||Juan M. Restrepo, University of Arizona|
|Abstract: Wind- and current-driven flotsam, oil spills, pollutants, and nutrients, approaching the nearshore will frequently appear to park just beyond the break zone, where waves break.
Moreover, the portion of these tracers that beach will do so only after a long
time. Explaining why these tracers park and at what rate they reach the shore
has important implications on a variety of different nearshore environmental issues, including the determination of what subscale processes are essential in computer models for the simulation of pollutant transport in the nearshore. Using a simple model we provide an explanation for the underlying mechanism responsible for the parking of tracers, not subject to inertial effects,
the role played by the bottom topography, and the non-uniform dispersion which leads, in some circumstances, to the eventual
landing of all or a portion of the tracers. We refer to the parking phenomenon in this environment as nearshore sticky waters|
