| Abstract | The accuracy of dispersion models is a widely debated topic. The goal of this research was to assess if the odour emission rates (OER) predicted using a simple Gaussian model were comparable to the more intensive and expensive wind tunnel-based odour measurement technique. A Gaussian dispersion model (STINK) was used to determine odour emission rates from piggery ponds. These values were then compared to those measured simultaneously on the pond surfaces using a wind tunnel, and analysed using dynamic olfactometry. Results of linear regressions showed a moderate relationship for two of the three seasons studied, and a very good relationship for the other season studied. Overall, the model showed a good correlation between calculated downwind, and calculated on-pond odour emission rates. The use of the STINK model shows promise as an alternative to the more labour-intensive direct emission rate measurement technique  |
