Use of Solute Transport Simulation in the Analysis of Field Problems UNITED STATES DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY RESTON, VA. 22092 In Reply Refer To: November 26, 1984 WGS-Mail Stop 411 GROUND WATER BRANCH TECHNICAL MEMORANDUM NO. 85.02 Subject: PROGRAMS AND PLANS--Use of Solute Transport Simulation in the Analysis of Field Problems During this summer, Debra Knopman of the Ground Water Branch conducted a telephone survey of all District Offices and most Subdistrict Offices to determine the past, present, and potential use of simulation in the analysis of field-scale solute transport problems. We wish to distribute some of the information obtained from this survey. Over the years, individuals within the Water Resources Division of the Geological Survey have gained considerable practical experience in the analysis of field-scale solute transport problems using quantitative analysis. A bibliography of reports that document the experience within the Division has been compiled and is attached for your information. In addition to assembling the bibliography, information on current and prospective District projects for each Region was compiled. A listing of the completed and ongoing projects is also attached. We hope these materials will open up more communication between professionals who are or will be studying the transport of solutes in ground-water systems. As solute transport analysis is complex, exchanging ideas among colleagues to obtain an appropriate approach to the problem is important. These attached materials should be of some value in assessing the state-of-the-art and our experience as an organization. If any of the attached information requires revisions, modifications, or additions, please contact Thomas Reilly, Solute Transport Technology Transfer Coordinator. Also, we would appreciate being notified as reports on the subject are published, and new projects initiated. (s) Eugene P.
