Two-dimensional simulation of drainage flow and tracer gas transport in the Geysers area
A simplified two-dimensional dynamical drainage flow model has been coupled with Monte Carlo transport and diffusion calculations to predict pollutant dispersion in drainage flow. The equations of motion and the mass continuity equation in a terrain-following coordinate system form the basis for the dynamical model. Model simulations of drainage flow and tracer gas transport were compared to observations from the 1980 ASCOT experiment in the Geysers area of northern California. The drainage flow simulations were made on a square grid 7 km on a side. The computational domain covered the drainages of Putah Creek, Gunning Creek, Anderson Creek, and Bear Canyon Creek, plus several other smaller canyons on the slopes of Cobb Mountain and the Mayacmas Mountains.
