Our new USG-Transport version 2.3.0 can be found here: https://www.gsienv.com/product/modflow-usg and includes changes that make the code more convenient to use with available compilers and FloPy tools. Two notable ones include:

  • The MULTIFILE option writes binary concentrations and solute masses on separate files for each species.
  • The density storage term due to solute mass is added to the other storage terms in the binary file.

This version also includes some bug fixes and updates to the documentation. This version release also includes the datasets for the example problems listed in the document. The ReadMe file included with the zip-file indicates the updates.

Major features of USG-Transport (USGT) include:

  • Structured and unstructured grid support
  • Connected linear network (CLNs) for simulating wells, pipes, streams, and wetlands using a variety of flow formulations (Laminar, Mannings, Hazen-Williams, Darcy-Weisbach)
  • Saturated-Unsaturated flow with 3-D Richards Equation
  • Multicomponent transport with chain decay
  • PFAS transport in vadose and saturated zones
  • Heat transport in vadose and saturated zones including with Borehole Heat Exchangers (BHEs)
  • Density-dependent flow and transport
  • PHREEQC integration* – Available as a separate executable on GSIs website
  • Many convenient features to assist modeler and speed up model runtimes and pre/postprocessing
  • Supported by GUIs such as Groundwater Vistas

Exciting News! The American Academy of Environmental Engineers and Scientists (AAEES) singularly honors Chuck Newell, Vice President/Principal Engineer with the prestigious 2024 Gordon Maskew Fair Award!

The award recognizes Dr. Newell’s extensive work in environmental science, including numerous publications, patents, and contributions to the field as exemplary of the goal to “protect and enhance environmental quality.” Congratulations on this well-deserved recognition!

The Gordon Maskew Fair Award honors one of the pioneers of environmental engineering, Dean Fair. In addition to his exemplary career, his living legacy includes hundreds of prominent practicing engineers and eminent professors who continue to emulate his values. He taught his students not only the technical aspects of the field but also inspired them to use their skills to protect and enhance environmental quality.

Through the Fair Award, the Academy seeks to identify Board Certified Environmental Engineers, Members, or Scientists who have contributed to the status of the environmental engineering or science professions by:

  • Exemplary professional conduct
  • Recognized achievements in the practice of environmental engineering and science
  • Significant contributions to the control of the quality of the world’s environment

Dr. Charles Newell holds the position of Vice President at GSI Environmental Inc. and is based in Houston, Texas. He is recognized as a Board Certified Environmental Engineer (BCEE) by the American Academy of Environmental Engineers and Scientists, a Certified Ground Water Professional by the National Ground Water Association (NGWA) and serves as an Adjunct Professor in the Department of Civil and Environmental Engineering at Rice University. His academic and professional contributions are extensive, including co-authorship of four U.S. EPA publications, 12 environmental software systems, over 70 journal articles, five patents, and two books, notably “Natural Attenuation of Fuels and Chlorinated Solvents”.

Dr. Newell’s areas of expertise encompass site characterization, groundwater modeling, risk assessment, natural attenuation, LNAPL/DNAPL, remediation technologies, long-term monitoring strategies, technology transfer, and management of PFAS-impacted sites.  He has served as a Principal or Co-Principal Investigator in numerous environmental R&D projects sponsored by various agencies and organizations, including the U.S. Department of Energy, American Petroleum Institute, U.S. Environmental Protection Agency, U.S. Department of Defense, and diverse industrial clients.

Dr. Newell is the recipient of the Hanson Excellence of Presentation Award from AAPG, the Outstanding Presentation Award from AIChE, and the 2001 Wesley W. Horner Award from ASCE. Additionally, he received the 2008 Outstanding Alumni Award from Rice University, the 2014 Strategic Environmental Research and Development Program (SERDP) Project of the Year Award, the 2016 Interstate Technology & Regulatory Council (ITRC) Environmental Excellence Award, and the 2020 Foundation Achievement Award from the Association for Environmental Health and Science.
