Visual Plumes (VP), is a Windows-based computer application that supersedes
the DOS PLUMES (Baumgartner, Frick, and Roberts, 1994. Dilution models for
effluent discharges, Third Edition. EPA/600/R-94/086) mixing zone modeling
system. VP simulates single and merging submerged aquatic plumes in
arbitrarily stratified ambient flow and buoyant surface discharges. Among its
new features are graphics, time-series input files, user specified units, a
conservative tidal background-pollutant build-up capability, a sensitivity
analysis capability, and a multi-stressor pathogen decay model that predicts
coliform bacteria mortality based on temperature, salinity, solar insolation,
and water column light absorption.
mixing characteristics of municipal ocean discharges. EPA/600/3-85/073a & b),
the surface discharge model PDS (Davis, 1999. Fundamentals of environmental
discharge modeling. CRC Press), the three-dimensional UM3 model based on UM,
and the NRFIELD model based on RSB. These models may be run consecutively and
compared graphically to help verify their performance. The Brooks equations
are retained to simulate far-field behavior. Finally, DOS PLUMES may be
selected as one of the "models," giving full access to its capabilities.
