EPA's Complex Terrain Model Development Program (CTMDP) was designed to develop reliable atmospheric dispersion models applicable to large pollutant sources located in complex terrain. The primary emphasis was on plume impaction on nearby hills during nighttime stable conditions. EPA's Fluid Modeling Facility (FMF) interacted closely with the model developers participating in the CTMDP and provided support in various ways through the conduct of a wide range of laboratory studies. Work at the FMF prior to the inception of the program provided the basic framework for the model, the dividing-streamline concept, and the focal point around which the field program was designed. At the beginning of the program, the FMF provided direct support as an aid to planning the details and strategies of the field experiments and testing the limits of applicability of the dividing-streamline concept. Later work included exercises of 'filling in the gaps' in the field data, furthering the understanding of the physical mechanisms important to plume impaction in complex terrain and in stably stratified flows in general, testing various modeling assumptions, providing data for 'calibration' of various modeling parameters, and testing the ability of the laboratory models to simulate full-scale conditions.
