An existing shelterbelt turbulence model, previously used only for neutral flow applications, is modified to investigate how stably stratified flow interacts with a porous obstacle. The model extension demonstrates that for uniformly dense barriers, temperature stratification hinders flow recovery in the barrier lee, thereby creating somewhat cooler temperatures from the upstream-of-windbreak conditions. The stably stratified conditions are then applied to a domain for monitoring odor transport from a livestock facility. Mapping a poultry house onto the model grid allows for representation of plausible flow patterns over a bluff-body obstacle. The pattern of odor transport from the house appears to be realistic, but validation with measurements and future testing is sought. Adding a shelterbelt configuration downstream of the emission source improves plume dilution, with the most dense and tallest arrangements creating the vertical displacement and turbulence to disperse strong intensity odor aloft rather than at the surface.
