Intrusive Activities in Dams and Levees – Are They Worth the Risk of Creating a Flaw?


This event qualifies for 2 PDHs


Join us on March 12, from 12:00 PM - 2:00 PM Eastern for Intrusive Activities in Dams and Levees – Are They Worth the Risk of Creating a Flaw? The U.S. Army Corps of Engineers has updated its regulation ER 1110-1-1807, Drilling and Invasive Activities at Dams and Levees, and related guidance based on what has been observed and learned during the last nine years of reviewing drilling program plans. This webinar will describe the update, which includes expansion to cover invasive activities for all dam and levee structures such as concrete dams and flood walls. The webinar also presents a different way to think about the risks related to drilling and invasive activities related to dams and levees, along with a short primer on hydraulic fracturing calculations related to fluids in borings. The processes and concepts presented are applicable to all dams and levees.

 

Learning objectives attendees will receive from this webinar:

  • Review updates to Drilling and Invasive Activities at Dams and Levees (ER 1110-1 1807).
  • Learn about problems that have occurred during drilling and lessons learned.
  • Understand how a risk-informed perspective on invasive activities and their related flaws might change your views on these activities.
  • Gain a better understanding of the basics of hydraulic fracturing and how to estimate related factors of safety.
  • Understand why cavity expansion theory is not appropriate for hydraulic fracturing related to dams and levees.
