Seepage Through Earth Dams: Instructors

John France, PE, D.GE, D.WRE
JWF Consulting LLC
President

John France is a registered professional engineer with over 45 years of consulting engineering experience over which time he has worked on hundreds of civil engineering projects. He received BS and MS degrees in civil engineering from Cornell University. For the past 40 years, his professional career has been focused on dam engineering and dam safety services. During his career, Mr. France has been involved in various capacities in evaluating and remediating seepage issues for earth dams. He has written numerous papers on the topic, and in 2012, he was an invited speaker at a FEMA workshop on filters and seepage remediation. He was also engaged by the Montana Dam Safety office to prepare a technical note on chimney filter design for posting on the State’s website. Together with Jennifer Williams, Mr. France has presented workshops on internal erosion failure modes for ASDSO and the States of Colorado and Wyoming.

John Cyganiewicz, PE
Cyganiewicz Geotechnical, LLC
President

John Cyganiewicz is a registered professional engineer with over 45 years of engineering experience specializing in the dam safety practice. He received his BS degree at the University of Rhode Island and has completed graduate level studies at the University of Rhode Island, University of Colorado, and University of California – Berkeley. Mr. Cyganiewicz retired in 2008 from a 32-year career at the Bureau of Reclamation and has continued to work as a consultant for several dam safety rehabilitation projects. Mr. Cyganiewicz was a leader in developing Reclamation’s risk analysis methodology with a specialization in seepage and piping issues of embankment dams and in the development of a toolbox compiled to provide guidance in seepage and piping risk analyses.  As an invited speaker, Mr. Cyganiewicz has made numerous presentations at technical meetings of various professional societies including ASDSO, USSD, NZCOLD, ANCOLD, and ICOLD. The presentations focused on design and construction of embankment dams, seepage and piping related issues, and risk analysis with a specialty in seepage and piping.
