Dispersion Modelling
Environmental Research Group
Dispersion Modelling Background
T
he Environmental Research Group (ERG) is one of the UK’s leading providers of detailed dispersion modelling assessments for regional and local authorities, the Environment Agency and private companies. Much of the modelling work is closely associated with emissions inventory developments such as the London Atmospheric Emissions Inventory, but also relates to the assessment of road traffic impacts, large industrial processes, Local Authority review and assessment, shipping and environmental impacts of large infrastructure developments.
ERG model development ERG has for a number of years developed a unique air quality management system, the ‘London Air Pollution Toolkit’. This has been the model of choice for a number of important developments for London, from detailed modelling as part of the review and assessment process, to estimating the impacts associated with the London Low Emission Zone (LEZ) (1) and Congestion Charging Scheme. Additionally the ‘Toolkit’ has provided the basis for environmental impacts for a wide variety of schemes, including the Thames Gateway, container terminal development, the Greenwich Peninsula development, the new Thames river crossing and in support in the Mayor of London’s air quality strategy.
Features • Unique methods used to provide the most detailed spatial maps possible. Predictions made at 5m intervals are possible. Use of accurate road networks allow detailed air pollution exposure assessments. • Outputs are compatible with GIS tools. • Unique treatment of NOX/NO2 chemistry (2) and new PM10 model(3), incorporating PM2.5 results. • Extensive Validation undertaken using London Air Quality Network (LAQN) dataset and statistical treatment of sources emitting pollutants at different heights. • Utilises most recent street canyon model (OSPM v5.0.64). • Capable of modelling > 1 million individual sources each with different source characteristics
Other modelling capabilities
Recent contracts
In addition to the ‘Toolkit’, ERG also use individual models, such as OSPM, ADMS and AERMOD, for specific modelling requirements, for example, the effects of shipping, large industrial processes (4), detailed street canyon studies and in support of large infrastructure developments.
• Estimating the air pollution impact of the Thames Gateway container terminal development. • Estimating the air pollution impact of the proposed Greenwich Peninsula Project. • The impact of the 3rd London River Crossing. • The London Low Emission Zone feasibility study. • Local authority review and assessment Stage 4, USA and detailed assessments • The air pollution effects of implementing the congestion charging scheme in London

Environment Agency Modelling Software (5) ERG provide innovative solutions to modelling problems, an example of which is the software developed for the Environment Agency study of large industrial plant in the East Thames corridor (5). The software allowed the analysis of scenarios to be make without lengthy model runs being undertaken.
