This research program was initiated with the overall objectives of gaining a better understanding of flow and diffusion of pollutants in complex terrain under both neutral and stably stratified conditions, providing a sound data base for testing existing theories, and developing new theories of flow and diffusion around isolated hills and ridges. To this end, experiments were conducted with models of a bell shaped hill and a 2-D steep ridge in EPA's meteorological wind tunnel and salt-water stratified towing tanks. Measurements were made of the flow structure, as well as the concentration patterns around the hills due to point sources located at different heights and positions relative to the hills.
