OFFICE OF GROUND WATER TECHNICAL MEMORANDUM NO. 90.05

Subject:  PUBLICATIONS--Release of report, "Technical training
                        notes in ground-water hydrology:  Radial
                        flow to a well," by G. D. Bennett, T. E.
                        Reilly, and M. C. Hill

The subject report has been published as Water-Resources
Investigations Report 89-4134.  The report is a tutorial on the
basic concepts of radial flow in ground water and its
representation in numerical models.  A copy of the report is
attached.

The report contains a number of problems (with answers) to be
solved by the reader.  The discussion focuses on the physical
characteristics of the radial-flow system in the vicinity of a
well, particularly those characteristics that are common to most
well-aquifer systems the concepts of finite difference simulation
and flow-net analysis are used to illustrate these
characteristics.

We recommend that this report be made available to all ground-
water hydrologists.
