Cracking and Hydraulic Fracturing in Embankment Dams and Levees
June 14, 2016 at 12:00 PM EDT, 11:00 AM CDT, 10:00 AM MDT, 9:00 AM PDT
(120 minutes)
 
Cracks are likely to develop in most embankment dams and levees, and not just in those that are poorly constructed. This course will present some of the common conditions that can lead to adverse geostatic stress conditions, cracking, and hydraulic fracturing in embankments.
3-D Effects on Estimation of Gradients, Seepage Flows and Evaluation of Internal Erosion Potential Failure Modes
July 12, 2016 at 12:00 PM EDT, 11:00 AM CDT, 10:00 AM MDT, 9:00 AM PDT
(120 minutes)
 
This webinar will present the results of 2D and 3D numerical evaluations of seepage conditions around a developing piping defect. An updated model similar to the first 3D numerical model performed at the University of Florida beginning in about 1980 (Townsend, 1981) will be presented to illustrate the importance of 3D influences on estimated seepage gradients, seepage flows and the evaluation of potential internal erosion potential failure modes.
The Application of Geophysics in the Design, Construction and Operation of Dams
August 9, 2016 at 12:00 PM EDT, 11:00 AM CDT, 10:00 AM MDT, 9:00 AM PDT
(120 minutes)
 
Understanding groundwater conditions, flow pathways, and seepage around and below dams is essential to remediate any conditions that may impact long-term stability, integrity, and operation of dam structures and reservoirs. Electrical resistivity imaging (ERI) and spontaneous potential (SP) surveys are primarily used to characterize subsurface geology, identify potential fractures or karst features, and locate seepage pathways beneath dam structures.
Hydrologic Hazards Estimating Probabilities of Extreme Floods
October 11, 2016 at 12:00 PM EDT, 11:00 AM CDT, 10:00 AM MDT, 9:00 AM PDT
(120 minutes)
 
This webinar provides an overview and background on current data and methods used in estimating hydrologic hazard curves for dam and levee safety.
Intro to Tailings Dam and Coal Ash Impoundment Design, Construction and Monitoring: What Can Go Wrong and Right?
November 8, 2016 at 12:00 PM EST, 11:00 AM CST, 10:00 AM MST, 9:00 AM PST
(120 minutes)
 
This course provides an overview of the unique construction and design components of these facilities. This course will examine a number of recent failures that have plagued the industry but provide valuable lessons for the future.
Introduction to Dam Decommissioning
December 13, 2016 at 12:00 PM EST, 11:00 AM CST, 10:00 AM MST, 9:00 AM PST
(120 minutes)
 
As dams deteriorate, or as their purpose and benefits diminish, there may come a time when the appropriate action is to decommission the dam. For some dams, this can be a very simple, rapid and inexpensive undertaking. For other dams, it can be a very complex and costly process, requiring years to accomplish. The purpose of this webinar is to provide an overview of recent trends in dam decommissioning in the United States with an emphasis on the engineering and design aspects of dam decommissioning.
