The Offshore Coastal Dispersion (OCD) model was adapted from the EPA guideline model MPTER to simulate the effect of offshore emissions from point sources in coastal regions. Modifications were made to incorporate overwater plume transport and dispersion as well as changes that occur as the plume crosses the shoreline. Hourly meteorological data are needed from overwater and overland locations. For overwater dispersion, the turbulence intensities are parameterized from boundary layer similarity relationships if they are not measured. A virtual source technique is used to change the rate of plume growth as the overwater plume intercepts the overland internal boundary layer.
