Earl Greene, Hydrologist, provides science support to the Chief Scientist for Water and the Associate Director for Water on various National Research Program issues. I did my graduate work at the University of Idaho. I began my Federal career with the Research Branch of the US Forest Service in 1983 and moved to the USGS South Dakota Water District Office as a Research Hydrologist and Project Chief in 1986. From 1995 to 1998 I worked with the National Research Program, with a focus on modeling flow and transport of water in karst and fractured rock terrain. From 1998 to 2005 I was the Hydrogeology Section Chief and Groundwater Specialist for the MD-DE-DC Water Science Center. In 2005, I transferred to a USGS Headquarters staff position in the Office of the Chief Scientist for Hydrology where I currently provide coordination for hydrologic research and science within the Hydrologic Research and Development program and the Hydrologic and Networks Analysis Program.
US Geological Survey Reston, VA
Staff Scientist for the National Research Program (NRP), a $42 million dollar program that conducts basic and applied research in hydrology, hydraulics, hydrogeology, ecology, and chemistry in support of the mission of the U.S. Geological Survey (USGS). The NRP consists of 3 National Laboratories with a research staff of about 380 permanent and non- permanent scientists and support individuals. The NRP is designed to encourage pursuit of a diverse agenda of basic research topics aimed at providing new knowledge and insights into varied and complex hydrologic processes that are not well understood. The emphasis of these research activities changes through time, reflecting the emergence of promising new areas of inquiry and the demand for new tools and techniques with which to address the nation’s most pressing water-resources issues. I serve as a major focal point for the NRP on all matters on all USGS scientific programs. I provide leadership to teams that make strategic recommendations and provide program planning, management, and evaluation of USGS research programs. I regularly write position papers, conduct analyses, and/or provide other documentation regarding scientific program priorities, impacts, and ramifications for Senior Executive Service (SES) Managers to consider. I serve as a liaison to water and science managers in other Federal Agencies and provide consultation and exchange information regarding highly visible science programs and research for the nation.

1/2001 - Present
Instructor for Graduate Course 420.604.01 -- Hydrology and Water Resources, this is a core course for a Master of Science in Environmental Sciences, Zanvyl Krieger School of Arts and Sciences. The course introduces the students to the fundamental physical principles that are necessary to understand the occurrence, distribution, and circulation of water near the Earth’s surface. I teach Graduate students about the hydrologic cycle and the influence climate, geology, and human activity has on this cycle. We study the principles of precipitation and evapotranspiration, runoff, floods, storage in natural and artificial reservoirs, hydrogeology, and watershed hydrology. I teach this course Spring and Fall Semesters.

District Ground Water Specialist
10/2001 - 8/2005
As ground-water discipline specialist my duties were to develop scientific programs and provide technical guidance and direction to the planning, cost analysis, execution, and quality control of all aspects of ground-water projects in the MD-DE-DC area. I had the final review responsibility for the USGS on technical methods, accuracy, and adequacy of ground-water projects. In addition I conducted basic and applied research investigations relating to the occurrence, movement, quality, quantity and use of water and the interrelationships between the water and the environment. My research projects were: 1) Characterization of fracture flow in and near the Washington Metro Subway System 2) Development of regional statistical methods to map areas of ground- water vulnerability 3) Development of methods for characterizing water-supply in fractured rock settings.

11/1998 - 10/2001
Chief of the Hydrogeologic Studies Section of the MD-DE-DC District office. The section was composed of a diverse set of scientists including; Hydrologists, Physical Scientists, Geographers, and Technicians. I provided guidance and leadership to direct theoretical and practical studies and experiments to investigate the occurrence, movement, quantity, and characterize the quality of the water resources as identified by the scientific community. Studies were designed to address hydrologic problems that were broad in scope and extremely complex in nature. In addition I served as District Ground-Water Specialist. Examples of projects I developed and supervised included: 1) Virus and Pathogen Transport in Coastal Plain and Fractured Rock Aquifers; 2) Characterization of Fracture Flow in and near the Washington Metro Transit Authority Tunnels; 3) Water-Supply Investigations of New Aquifers; 4) Investigation of Nutrient Inputs (Surface and Ground Water) into the MD Inland Bays; and 5) Spatial modeling of ground-water quality in the Mid-Atlantic Region.

5/1995 - 11/1998
Three-year detail to conduct basic and applied research investigations related to the occurrence, movement, quality, quantity and use of water and the interrelationships between the water and the environment. My three major accomplishments during this detail were to: A) Developed a flow and transport model to characterize and investigate scale-dependent diffuse and conduit transport processes in fractured and karst aquifers; B) published a paper inGround Water on the use of stable isotopes to trace recharge waters from sources to sinks in a karst aquifer; and C) Developed and published in Ground Water and in a USGS Open-File Report a method of conducting and interpreting prematurely terminated air- pressurized slug tests to estimate hydraulic properties of contaminated and low permeable geologic formations.
US Geological Survey Rapid City, SD
8/1989 - 5/1993
Provided leadership to guide a multidisciplinary investigation to characterize the hydraulic and transport properties of a fractured and solution-enhanced carbonate aquifer. Research goals were based upon developing an understanding of the role heterogeneity and scale play in characterizing fluid flow and chemical transport. As principle researcher I coordinated the efforts of University Scientists, District Scientists, and NRP Researchers to complete the goals of the project.
Major accomplishments during this time: 1) Published a paper in Ground Water that used the combined multidisciplinary data from geophysical logs, hydraulic testing, and fracture mapping to characterize localized anisotropic controls on ground-water flow and its relation to cave, fractures, joints in karst aquifer; 2) Quantified and interpreted borehole geophysical data to characterize porosity and hydraulic controls in a carbonate aquifer. Paper published in the international forum of the Minerals and Geotechnical Logging Society; and 3) Completed two Irrigation Drainage studies in western South Dakota as part of the Water Resources Divisions Contribution to the DOI –National Irrigation Drainage Water Quality Program.
Bureau of Land Management Dickinson, ND
6/1985 - 8/1989
Provided leadership to District Scientists to determine the kinds and types of sampling and statistical methods needed to collect and analyze hydrologic and climatological data. Inventoried and analyzed data on floods, alluvial valley floors, hydrogeology, runoff, load calculations, and watershed characteristics. Determined the impacts of proposed BLM management actions on the surface and ground-water resources through EIS’s, EA’s, monitoring plans, and/or activity plans.
