9/16/2023 0 Comments Ausplume Model![]() Odour impact areas can be defined by plotting odour concentrations corresponding to selected values for odour impact criteria. OIA uses inputs of source odour concentration, ventilation rate, emission strength and topography information together with meteorological data and ODM to determine odour dispersion around the source. ![]() Odour Impact Assessment (OIA) is an effective tool used to prepare environmental management plans, and develop appropriate regional and local planning and development control instruments. ODM results should be validated by undertaking an odour community survey or an odour complaint history. Modelling is most effective when a comprehensive study is carried out. Odour Dispersion Modelling (ODM) provides a benchmark for the prediction of the impact of odour. Within this area, it is reasonable to assume that local residents will experience some degree of odour annoyance. ![]() The output from the model can be checked against odour impact criteria to derive an odour impact area. An air dispersion model predicts downwind odour concentrations on the basis of odour emission rates, topography and meteorological data. ![]()
