Description:
A wind tunnel study was conducted to determine maximum ground-level concentrations for a variety of source positions (locations and heights) both upstream and downstream of two model hills, an axisymmetric hill and a two-dimensional ridge, immersed in a simulated neutral atmospheric boundary layer. errain amplification factors derived from these measurements were used to construct contour plots showing regions or 'windows' of enhanced ground-level concentration. hese windows of enhanced ground-level concentration are shown to be a useful guide for estimating the effects of complex terrain on pollutant dispersion or, conversely, for determining source locations near complex terrain which minimize the enhancement of ground-level concentration.
