Assessment of the Performance of an In-Field Gaussian Plume/Puff Model for Overwater Use

Abstract

A chemical hazard forecast computer model is tested for consistency with field data which was used in its development. The model's attempt to forecast puff dispersion, for which a parameterization has not been developed, are examined by comparison to relative dispersion data sets. The parameterizations developed from the NPS data set are compared to an independently derived set of parameterizations demonstrating the generic applicability of the model. It was found that the model predicts the total width over which a hazard might occur reasonably well but underpredicts the downwind hazard distance. This is due to lack of separate consideration of meander effects. Keywords: Overwater diffusion; Burst release.
