Campagne de mesure des odeurs sur le CET "Cour-au-Bois" à Braine-le- Château Estimation des nuisances olfactives et suggestion d'une méthode simplifiée.

The study is made in the frame of a follow-up monitoring of all landfill sites in Wallonia, initiated by the Ministry of Environment and managed by ISSeP. The research group applied a field inspection technique based on the perception of a panel of experts sniffing the air around the region of interest and trying to delineate the odour plume. In a second step, the recorded meteorological data are entered into an atmospheric dispersion model and the odour emission rate of the facility is adjusted until the predicted odour impact zone fits about exactly the one which is measured in the field. The present report concerns the site of Braine-le-Château. It presents also a possible simplified method based on a simple version of the Gaussian dispersion formula.
