Dam Safety 2019: Technical Workshop - Evaluation and Rehabilitation of Embankment Dams for Seepage Concerns

When: Thursday, September 12 - 8:30 am - 4:30 pm

Registration Fees: $300 per person includes all course instruction and materials as well as beverage breaks. 

Professional Development Hours: Up to 7 professional development hours are available for attending the full workshop. Attendees will receive a form on which to record contact hours for continuing education credits.

Overview: Evaluation and rehabilitation of existing embankment dams for seepage deficiencies is one of the most common challenges in dam safety today. This is because internal erosion caused by seepage through and under dams remains one of the leading causes of dam failure. In simplest terms, embankment dam seepage problems can be addressed in two ways: 1) cutoff or reduce the flow or 2) safely collect and control it.

This workshop has three major sections:

  • Identification and evaluation of seepage concerns,
  • Overview of internal erosion potential failure modes, and
  • Rehabilitation methods by flow reduction or seepage collection.

Case histories will be used for illustration purposes and exercises will be included to reinforce the presentations.
