MULTI AQUIFER RESPONSE TO PUMPING
How to correctly interpret pumping tests in leaky aquifers? How to evaluate the hydraulic properties of aquifers and confining layers (aquifers, aquitards) on the basis of properly designed and executed pumping tests?
This webinar explores, on the basis of analytical and numerical studies, the manner in which pressure signals created by pumping or injection propagate through a system of hydraulically interconnected aquifers and confining units (aquifers, aquitards), and the manner in which this impacts drawdowns or buildups in a pumped aquifer as well as other aquifers and confining layers above and below. It then discusses methods of inferring the hydraulic properties of aquifers and aquitards from pumping tests and illustrates them on two month-long pumping tests previously conducted by the instructor and his coworkers in a three-aquifer two-aquitard system near Oxnard, California.
HIGHLIGHTS:
- What is a multiaquifer system?
- Analytical and numerical models of pressure propagation through multiaquifer systems.
- Critique of traditional leaky-aquifer models and corresponding methods of test interpration.
- Alternative methods of determining the hydraulic properties of aquifers and confining units in a multilayer system.
- Application to two month-long pumping tests in a three-aquifer two-aquitard system near Oxnard, California.
WHAT YOU WILL GAIN:
- New insight into the hydraulic response of a multiaquifer system to pumping.
- Appreciate the shortcomings of traditional leaky aquifer methods of test interpretation.
- Learn improved techniques to interpret pumping tests in multiaquifer systems.
- Learn from a corresponding case study near Oxnard, Califronia.

Instructors Bio
Shlomo P. Neuman is Regents Professor of Hydrology and Water Resources at the University of Arizona in Tucson. Dr. Neuman's research has spanned the development and application of hydraulic and pneumatic field tests for the characterization of aquifer, aquitards and fractured rock hydrologic properties; geostatistical methods for multiscale spatial analyses of hydrologic data; development and application of stochastic methods to describe mathematically fluid flow and solute transport when soil and rock properties vary randomly in space, and with scale; development of computational algorithms and computer programs to predict subsurface flow, and solute concentrations, under uncertainty, and to assess the associated prediction errors; estimation of flow and transport model parameters under uncertainty; and use of such computational models to help assess subsurface contamination, identify contaminant sources, design groundwater monitoring networks, and aid the design of remedial operations.
Professor Neuman has summarized his scientific contributions in over 310 professional papers, books and reports His name appears on two ISI lists of Highly Cited Researchers, one in Engineering and one in Environmental Science. Professor Neuman is a member of the U.S. National Academy of Engineering; Fellow of the American Geophysical Union, the Geological Society of America, and Galileo Circle of the U of A College of Science; Concurrent Professor of Nanjing University in China; and Honorary Professor of the Nanjing Hydraulic Research Institute in China.
Professor Neuman has received numerous awards and honors including the Robert E. Horton Medal and the Hydrology Award from the American Geophysical Union, the O.E. Meinzer Award from the Geological Society of America, the M.K. Hubbert Award from the Association of Groundwater Scientists and Engineers, the C.V. Theis Award from the American Institute of Hydrology, and a certificate of appreciation by the U.S. Department of Agriculture.
He was named Birdsall Distinguished Lecturer by the Geological Society of America, and fourth Langbein Lecturer in Hydrology by the American Geophysical Union. Over 34 doctoral students and 26 master students have completed their degrees under Professor Neuman’s supervision at the U of A by 2009, many of whom have gone on to hold prominent positions in academia, government and industry. In 1998 and 2008, Professor Neuman's students and colleagues had organized international symposia in Tucson to honor his 60 and 70 birthdays, one of which resulted in a published Geological Society of America Memoir.
An Autobiography of Professor Neuman has been published by the journal in 2008, and a taped interview has been prepared for The Hydrogeologist Time Capsule at: http://timecapsule.ecodev.ch/video.html
