Atmospheric Dispersion Models 1) Gaussian Model 2) Puff Model 3) MUC Model

Gaussian Model The Gaussian Model is one of the most widely used models in the world to study dispersion phenomena, notably by the EPA (Environmental Protection Agency). This model estimates pollutant concentrations at any point in space based on various factors: Wind Speed & Direction Atmospheric Stability Mixing Height Temperature Gaussian Dispersion Plume

The Gaussian Model is one of the most widely used models in the world to study dispersion phenomena, notably by the EPA (Environmental Protection Agency). This model estimates pollutant concentrations at any point in space based on various factors:

Wind Speed & Direction

Atmospheric Stability

Mixing Height

Temperature

Puff Model The Puff Model was designed to simulate instantaneous releases into the atmosphere. This model is used to predict the impact of an accident (tanker truck, holding tank leak or broken pipeline) to allow effective emergency planning. Puff Model Simulation

The Puff Model was designed to simulate instantaneous releases into the atmosphere.

This model is used to predict the impact of an accident (tanker truck, holding tank leak or broken pipeline) to allow effective emergency planning.

MUC Model The MUC (Montreal Urban Community) model comprises the four formulae specified in MUC By-Law 90 regarding the atmospheric dispersion of gaseous contaminants. Simulation with MUC Model

The MUC (Montreal Urban Community) model comprises the four formulae specified in MUC By-Law 90 regarding the atmospheric dispersion of gaseous contaminants.

Plume Rise Polair © 4.2 takes in account the plume rise elevation by correcting the value of the stack height. In order to effectively evaluate this height, 3 models can be used: U.S. Environmental Protection Agency (EPA) Holland Montreal Urban Community (MUC)
