dispersion modelling

dispersion modelling

Our trained consultants utilise atmospheric dispersion modelling to visualise and quantify the spread of a pollutant from its source.

We use ADMS software to complete our assessments, as it allows us to model a variety of emission sources, such as;

  • Point sources – eg. Stacks or Vents
  • Area sources – eg. Biofilters or lagoons
  • Volume sources – eg. Compost piles or transport vehicles
  • Line sources – eg. Streams or conveyor belts
  • Jet sources – eg. Horizontal vents


The computational model requires emission data and meteorological information to quantify the local impact caused by pollutant emission. ADMS takes into account the effects of buildings and terrain, and processes the information into ground level concentrations of the pollutant. The resulting information can be used to achieve a number of goals, such as;

  1. Assess local pollutant impact against air quality objectives and legislation
  2. Determine stack height and diameter
  3. Help in the design and layout of process operations to reduce nuisance impact
  4. Quantify the effectiveness of abatement equipment
  5. Site investigations to identify the true impact of existing emission sources
