AirQUIS: Dispersion models
The vertical component of the wind is generated internally in the model based on the horizontal wind-components and a 3D divergence free condition for the wind field. Vertical diffusion ( ... similarity theory is applied in order to parameterize the vertical eddy diffusion coefficient, K (Shir, 1973; Businger and Arya, 1974) Horizontal and vertical turbulence parameters may be calculated internally in ...

Acid Mine Drainage at the Nickel Rim Mine Tailings
H buffering zones. Vertical profile showing saturation indices and corresponding pH-buffering regions Modified from Johnson et al., ... oxidation zone have been great enough to cement the tailings. The cemented layers limit O2 diffusion, resulting in longer oxidation times for the tailings. High concentrations of Fe and SO4 ...

MINTOX - Nickel Rim Mine Site Plume
D vertical cross-section to the aquifer at the pyrrhotite-rich Nickel Rim tailings impoundment near ... metals is shown to be highly dependent on tailings mineralogy, moisture content and oxygen diffusion rates, with important implications on predictive uncertainty and the selection of remedial alternatives. The ...

Salt Fingers Lab Demo
A downward moving finger of warm saline water (see diagram) cools off via molecular diffusion of heat, and therefore becomes more dense. This ... gains heat from the surrounding fingers, becomes lighter, and rises. The net effect is a vertical exchange of water containing the salt, and hence a downwards salt flux. The heat flux ...

The Source Recharge Area: mass loading of contamination to the ground water
This tortuous-vertical flow tends to laterally distribute any contaminant discharged to water table over a greater area ... soil solution along with any contaminants that may be transported as dissolved phase. Along with diffusion, mechanical mixing is responsible for dispersion of contaminants as the soil solution drains to the ...
