PLUMES2.0 Model for Effluent Plume Dilution, Mixing Zone Analysis, and Diffuser Design
The U.S. Environmental Protection Agency (USEPA) in collaboration with the Salish Sea Modeling Center (SSMC) at the University of Washington developed the PLUMES2.0 model. It is a model for conducting effluent plume dilution and mixing zone analysis. It may also be used for diffuser design and siting studies. The ability to conduct effluent fate and transport using standalone public domain software with a graphical user interface (GUI) is a core need of the National Pollutant Discharge Elimination System (NPDES) program. PLUMES2.0 is a Fortran version of the USEPA model Visual Plumes that was originally written in Pascal by the developer Dr. Walter Frick of USEPA.
The model description and user instructions are in the associated User Manual document
“Khangaonkar, TP , L Premathilake, B Cope, C Knightes, and A Tseng. December 2024. PLUMES2.0. Model Theory and User Manual. EPA/600/B-24/339”
PLUMES2.0 software is distributed in the form of a self-extracting zip file. The software and the User Manual may be downloaded from the following locations.
