ground dispersion
1dispersion — The spreading and mixing of chemical constituents in ground water caused by diffusion and mixing due to microscopic variations in velocities within and between pores [6] …
2dispersion — i. Spreading or scattering shots about a target in air to air or air to ground gunnery. ii. The average distance from the aiming point of bombs or other armament dropped under identical conditions. iii. The process in which electromagnetic… …
3Atmospheric dispersion modeling — Industrial air pollution source Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms… …
4Compilation of atmospheric dispersion models — Atmospheric dispersion models are computer programs that use mathematical algorithms to simulate how pollutants in the ambient atmosphere disperse and, in some cases, how they react in the atmosphere. The dispersion models are used to estimate or …
