HIGRAD: PLUME DISPERSAL
in Salt Lake City (2.8 Mb avi)
3-d dispersion in downtown Salt
Lake City. Six tracers are shown as they disperse with a southeasterly
wind. To learn more about this project visit the Chem-Bio
Transport and Fate web page.
SLC
fly-through (0.7 Mb mpg)
Shows a bird's eye view of our
3-d Salt Lake City building data set. These building data sets
are required by the building-scale and regional scale modeling
teams. To learn more about this project visit the Chem-Bio
Transport and Fate web page.
Storm
water flow (0.8 Mb QT) in one of the Santa Monica
Bay sub-watersheds.
The urban runoff and pipe flow was simulated using the SWMM
model and rain gauge measurements. To learn more about this
project visit the Urban Security
Air-Water Pathways web page.
Storm
water quality (0.7 Mb QT) resulting
from atmospheric deposition in one of the Santa Monica Bay sub-watersheds.
Deposition was
estimated using the CIT photochemical model and the water quality
was modeled using SWMM. To learn more about this project visit
the Urban Security Air-Water
Pathways web page.
Dispersion
from a low release (0.3 Mb mpeg) and an
elevated release (0.4 Mb mpeg) on the back side of a building.
Dispersion
within a cluster of buildings
(0.2 Mb mpeg)
In this wind tunnel experiment the wind is
coming out of the picture. Notice that the plume circulates between
the two smaller buildings in a direction opposite the prevailing
wind. To learn more about this work visit the Chem-Bio
Transport and Fate and USEPA
Fluid Modeling Facility web pages.
A HOTMAC/RAPTAD simulated
plume release (0.2 Mb gif) in the El Paso/Ciudad Juarez
Region.
The movie shows neutrally-buoyant particles being transported
by the mean and turbulent wind fields for 3 days of a 30 day
simulation (Sept. 10-12, 1994). To learn more about this project
visit the El Paso/Ciudad Juarez web
page. To learn more about the meteorological and dispersion
models visit the Model Descriptions web
page.
