A software application for mapping livestock waste odour dispersion
نویسندگان
چکیده
10 In developed Countries, coexistence of livestock production and urban settlements is a source of 11 problematic interactions that are regulated by specific legislation, often requiring the evaluation of 12 the potential environmental impact of livestock odour emissions. For this purpose, dispersion 13 models are powerful tools that can be classified as dynamic (Eulerian and Lagrangian) or static 14 (Gaussian). The latter, while presenting some limitations in condition of wind calm and complex 15 orography, are widely adopted for their ease of use. 16 OdiGauss is a free multilingual software application allowing to estimate odour dispersion from 17 multiple point sources and to generate the related maps. Dispersion is calculated according to a 18 Gaussian approach, as a function of wind speed and direction, precipitation, temperature, and solar 19 radiation. OdiGauss incorporates a model of odour emissions from poultry farms (EmiFarm) which 20 makes predictions based on manure production and management. Two case studies of software 21 application on real poultry and swine farms are presented. 22

Livestock Odour Dispersion Modeling: A Review
Abstract This paper reviewed the studies of livestock odour dispersion modeling including odor sources, odor emission rate, odor characteristics and measurements, odor dispersion modeling methods, and methods and results of adapting industrial air dispersion models for livestock odor dispersion simulations. The Gaussian plume models, Puff models, Fluctuating models and other models that have be...
متن کاملEvaluation of odour impact from a landfill area and a waste treatment facility through the application of two approaches of a Gaussian dispersion model
Odour emission from landfill areas has a high potential to cause significant annoyance to people living in their surroundings. In order to avoid odour nuisance, it is crucial to select the best location in the project phase of these facilities. In the present work, two approaches of the Gaussian atmospheric dispersion model were employed to predict odour impact from a projected landfill area an...
متن کاملEvaluation of Air Dispersion Models for Livestock Odour Application
Instantaneous downwind malodours from two swine farrowing facilities were assessed in the field by 15 trained human sniffers. A total of 34 1-hour field monitoring sessions were carried out on the two farms between June and October in 2003 and 2004. Odour emissions from the farm were measured and weather conditions were monitored simultaneously. Four air dispersion models, ISCST3, AUSPLUME, IN-...
متن کاملSeparation distance to avoid odour nuisance due to livestock calculated by the Austrian odour dispersion model (AODM)
Odour emission of livestock buildings is major burden for ambient residential areas. Using a dispersion model to calculate ambient odour concentrations, the separation distance between livestock buildings and residential areas was defined by a pre-selected odour threshold and an exceeding probability. The dynamic Austrian odour dispersion model (AODM) was used to calculate the separation distan...
متن کاملOdour Impact and Control at a Landfill Site in Hong Kong
In Hong Kong, landfill dumping has been a main approach for municipal solid wastes disposal and will be continued in the near future. However, gaseous emission from municipal waste may causes offensive odours and disturbs the neighbours around landfill sites. Usually there are not enough buffer zones between landfill sites and the nearest sensitive receptors due to a land restriction in Hong Ko...
