The mathematics of air quality modeling is discussed with special attention to problems associated with complex terrain. Practical solutions to some of these problems are suggested and an implementation is described as WYNDvalley, a dispersion model adapted to the study of trace species concentrations in near-stagnant conditions within complex valley drainage systems. The model is illustrated by application to the Methow, Twisp, and Chewack valleys of Okanogan County, Washington.
