The Briggs plume rise equations arise in the study of 'Atmospheric dispersion modeling'. The widely used equations studied in the model suggest that the Briggs' equations proposed for bent-over, hot buoyant plumes are the only relevant ones in general. Such models are important to governmental agencies tasked with protecting and managing the ambient air quality the models are typically employed to determine whether existing or proposed new industrial facilities are or will be in compliance with national ambient air quality standards. The models also serve to assist in the design of effective control strategies to reduce emissions of harmful air pollutants.
