The tests were performed utilizing 1:1920 scale models of the cooling towers and the terrain surrounding the Geysers Power Plant complex. Ground-level concentrations were measured along Big Sulphur Creek to study interaction of the cooling tower plumes with the natural drainage flow. Concentrations were also sampled at ground-level and vertically between the cooling towers and Anderson Springs at five different wind speeds and a predominantly west wind, under neutral conditions. Data obtained include velocity and temperature profiles, isopleths of ground-level concentration, vertical concentration distributions, and plume visualization photographs.reportsengCopyright and other restrictions may apply.
