Application of Coupled Prognostic Windfield and Lagrangian Dispersion Models for Air Quality Purposes in a Region of Coastal Terrain
High levels of mining, industrial and commercial activities are located in the vicinity of Hunter Valley, which extends inland for more than 150 km from the eastern coastline of Auistralia. The Electricity Commision of New South Wales operates two coal- fired power stations(Bayswater and Liddell)located 3km apart at a distance of 100 km up the valley. The Commission is concerned to assess the worst -case air quality impact of these stations and to know what the impact of possible new stations in the region might be. In this paper, we present a summertime case study in which field measurements of winds and sulfurdioxide copncentrations are compared to simulation results from a state- of-the-art regional air quality model (Physick et. al., 1991)
