Clifford I Voss, Ph.D.
Dr. Clifford Voss is a USGS Emeritus Scientist with the Water Resources Mission Area with over 40 years of project management, implementation, field and research experience in groundwater systems.
Dr. Clifford Voss is a USGS Emeritus Scientist with over 40 years of project management, implementation, field and research experience in groundwater systems. He deals with theoretical, field and practical issues in quantitative hydrogeology including: physics of subsurface fluids, computer model development and application to scientific evaluation of hydrogeologic systems, groundwater resources development and protection, coastal/island groundwater resources, subsurface energy production/storage, subsurface waste isolation, and cold-regions hydrology.
Dr. Voss is recognized as an international expert on groundwater modeling. He consults extensively on groundwater system evaluation and management, and lectures internationally on these and related subjects. The practical methodology and codes that Voss and his colleagues have developed (SUTRA and SutraSuite) are in standard use worldwide in subsurface assessment, aiding in quantity-quality management of groundwater resources and in evaluation of human impacts on the subsurface environment. These codes also allow development of a deeper understanding of important hydrogeologic processes.
His current interests involve: subsurface flow/transport in heterogeneous hydrogeologic media, cold-regions hydrology, development and application of practical methodology and subsurface hydrology simulation codes (SUTRA and SutraSuite) with freeze/thaw for study of ground-ice and permafrost in cold regions and associated code-benchmark development, flow and transport in variable-density subsurface fluids (seawater, brine, hot/cold groundwater), inverse modeling, network design, optimization of groundwater management, use of isotopes in characterizing subsurface systems, and the climate/ecology/society/water nexus.
Dr. Voss has conducted many crucial subsurface resource understanding and management studies, including: nuclear waste repository siting safety and performance (Sweden, Germany, Japan), coastal aquifer and seawater intrusion management (Hawaii USA, other USA, and worldwide), transboundary aquifer management (Nubian Aquifer of Egypt, Libya, Chad, Sudan); sustainability of arsenic-free groundwater supply (Bengal Delta Aquifer of India, Bangladesh); discovering the dynamics of cold-regions hydrologic systems (Canada, China, Greenland/Denmark, Sweden, USA).
Dr. Voss is Executive Editor of "Hydrogeology Journal" the official journal of the International Association of Hydrogeologists (since 1994).

Heat transport in the Red Lake Bog, Glacial Lake Agassiz Peatlands
We report the results of an investigation on the processes controlling heat transport in peat under a large bog in the Glacial Lake Agassiz Peatlands. For 2 years, starting in July 1998, we recorded temperature at 12 depth intervals from 0 to 400 cm within a vertical peat profile at the crest of the bog at sub‐daily intervals. We also recorded air temperature 1 m above the peat surface. We calcula

Freshwater-saltwater transition zone movement during aquifer storage and recovery cycles in Brooklyn and Queens, New York City, USA
Freshwater storage in deep aquifers of Brooklyn and Queens, New York, USA, is under consideration as an emergency water supply for New York City. The purpose of a New York City storage and recovery system is to provide an emergency water supply during times of drought or other contingencies and would entail longer-term storage phases than a typical annual cycle. There is concern amongst neighborin

Simulation of saltwater movement in the Upper Floridan aquifer in the Savannah, Georgia-Hilton Head Island, South Carolina, area, predevelopment-2004, and projected movement for 2000 pumping conditions
A digital model was developed to simulate ground-water flow and solute transport for the Upper Floridan aquifer in the Savannah, Georgia–Hilton Head Island, South Carolina, area. The model was used to (1) simulate trends of saltwater intrusion from predevelopment to the present day (1885–2004), (2) project these trends from the present day into the future, and (3) evaluate the relative influence o

Inverse modeling for seawater intrusion in coastal aquifers: Insights about parameter sensitivities, variances, correlations and estimation procedures derived from the Henry problem
Inverse modeling studies employing data collected from the classic Henry seawater intrusion problem give insight into several important aspects of inverse modeling of seawater intrusion problems and effective measurement strategies for estimation of parameters for seawater intrusion. Despite the simplicity of the Henry problem, it embodies the behavior of a typical seawater intrusion situation in

The future of hydrogeology
“The Future of Hydrogeology” would seem to be an overly ambitious topic for a theme issue of Hydrogeology Journal or for any other journal. Only a modicum of common sense and experience provides the insight that predicting the future of a science is a task fraught with uncertainty that should be approached with caution and humility. Please be assured that the intent of this issue of the journal is

Three-dimensional variable-density flow simulation of a coastal aquifer in southern Oahu, Hawaii, USA
Three-dimensional modeling of groundwater flow and solute transport in the Pearl Harbor aquifer, southern Oahu, Hawaii, shows that the readjustment of the freshwater–saltwater transition zone takes a long time following changes in pumping, irrigation, or recharge in the aquifer system. It takes about 50 years for the transition zone to move 90% of the distance to its new steady position. Further,

SutraGUI, a graphical-user interface for SUTRA, a model for ground-water flow with solute or energy transport
This report describes SutraGUI, a flexible graphical user-interface (GUI) that supports two-dimensional (2D) and three-dimensional (3D) simulation with the U.S. Geological Survey (USGS) SUTRA ground-water-flow and transport model (Voss and Provost, 2002). SutraGUI allows the user to create SUTRA ground-water models graphically. SutraGUI provides all of the graphical functionality required for sett

Announcing a Hydrogeology Journal theme issue on "The future of hydrogeology"
What is the future of hydrogeology? Are most of the fundamental scientific problems in hydrogeology already solved? Is there really any need for more fundamental research, field measurements, or method development? Have recent scientific advances really added capabilities and tools for our practical needs? Are there any unsolved hydrogeologic questions still remaining that are vital to our optimal

SUTRA: A model for 2D or 3D saturated-unsaturated, variable-density ground-water flow with solute or energy transport
SUTRA (Saturated-Unsaturated Transport) is a computer program that simulates fluid movement and the transport of either energy or dissolved substances in a subsurface environment. This upgraded version of SUTRA adds the capability for three-dimensional simulation to the former code (Voss, 1984), which allowed only two-dimensional simulation. The code employs a two- or three-dimensional finite-elem
