Description:

The report describes the theory and operation of a terrain preprocessor computer program which approximates actual terrain features with mathematical functions. The best-fit parameters for these functions are used by the Complex Terrain Dispersion Model (CTDM) in the calculation of lateral and vertical streamline displacement, an important step in the calculation of concentrations at hill receptor locations.
