Shoreline fumigation

Shoreline Fumigation - For rural sources within 3000 m of a large body of water, maximum shoreline fumigation concentrations can be estimated by SCREEN. A stable onshore flow is assumed with stability class F (A0/AZ = 0.035 K/m) and stack height wind speed of 2.5 m/s. Similar to the inversion break-up fumigation case, the maximum ground-level shoreline fumigation concentration is assumed to occur where the top of the stable... 

As with the inversion break-up case, the distance to maximum ground-level concentration is determined by iteration. The equation used for the shoreline fumigation case is ... 

Plume height is based on the assumed F stability and 2.5 m/s wind speed, and the dispersion parameter (o, ) incorporates the effects of buoyancy induced dispersion. If x , is less than 200 m, then no shoreline fumigation calculation is made, since the plume may still be influenced by transitional rise and its interaction with the TIBL is more difficult to model. 

The maximum ground-level concentration due to shoreline fumigation, Xf. is calculated from ... 

The Shoreline Dispersion Model (SDM) is a multipoint Gaussian dispersion model tliat can be used to determine ground-level concentrations from tall stationary point source emissions netir a shoreline emaromnent. SDM is used in conjunction witli MPTER algoritlnns to calculate concentrations when fumigation conditions do not exist.
