Workshop on Methods for Estimating Ground-Water Recharge
Lakewood, CO
February 26-28, 2002

A workshop on methods for estimating ground-water recharge was held in Building 810 of the Denver Federal Center in Lakewood, CO on February 26 to 28, 2002. The workshop consisted of a series of lectures and case studies. The goals of the workshop were to provide a survey of different methods that have been applied to the estimation of ground-water recharge, to review the theory on which the methods are based, to present in-depth examples of application of the methods, and to discuss advantages and limitations of all of the approachs.

The agenda for the workshop follows. Interested parties can contact authors for copies of presentations. Any questions on content of the workshop should be directed to Rick Healy (rwhealy@usgs.gov).
