Five Learning Objectives of This Course: Scour of rock is a dam safety concern that requires meaningful quantification It is possible to predict the scour potential of rock using data normally available for dam design High-resolution remote sensing and monitoring can facilitate improved scour assessment Course attendees should develop an understanding of processes and key drivers/controls for scour of rocks Course attendees should be able to e...

UFC – Minimum Antiterrorism Standards for DOD Buildings: This course is available to all Federal, State, local government and private sector SECURITY and ENGINEERING professionals. While the course focuses on securing DOD assets, the concepts learned are prudent and applicable in reducing criminal and terrorist threats to non-DOD buildings, as well. Contractors and consultants seeking construction contracts with the Department of Defense...

This webinar will review the design and construction of filters and drains for embankment dams. Specific topics covered will include 1) principles of filters and drains, 2) locations and configurations of filters and drains in embankment dams (for both new dams and dam rehabilitations) , 3) design guidelines for filters and drains, 4) evaluations of filters and drains in existing embankment dams, and 5) practical considerations for design and...

Potential failure modes analyses (PFMA) was first used in dam safety over twenty years ago and although thousands of PFMA workshops have been conducted since it was first introduced, the use and application of PFMAs is still mostly limited to larger federal agencies and occasionally by others on larger projects. PFMA is a tool and a framework to evaluate dam and levee safety. It has fundamentally changed the way many now approach assessing and...

This course will provide a thorough overview of the fundamentals of specifying the fresh and hardened properties of concrete mixes; the review of applicable codes for concrete hydraulic structures; the design philosophy and methodology of reinforced concrete hydraulic structures; and issues associated with the construction process. The course will include actual design examples of frequently used hydraulic structures utilizing current design c...

The most common deficiency at dams in North America is inadequate spillway capacity. Inadequate spillway capacity can result in overtopping of a dam during flood events. This is especially a concern for embankment dams where overtopping of the dam embankment can cause breaching of the dam and uncontrolled release of the impounded water. This failure mode accounts for more than 40 percent of recent dam failures. A broad overview of the many app...

The purpose of this course is to provide a brief introduction into the science of concrete arch dams. The review will touch on design methods used in the past, but primarily focus on the methods used in the current state of the practice. A historical review of construction techniques will be discussed, and how that relates to evaluations and the physical behavior of the structures. The basic loads and loading conditions used for analysis will...

This webinar will review the 2004 failure of Big Bay Dam. A potential failure modes framework was used to make the forensic root-cause assessment based on data and information provided by the State of Mississippi. A detailed timeline of the failure obtained through review of court proceedings will be presented including the appearance of a number of distress indicators, the seriousness of which were not recognized and acted upon by the Owner a...

This course is based on 50 years of NRCS experience with investigating and remediating cracked earth embankments. The presentation consists of two main sections, covering: 1) the nature of soil cracking and the associated internal erosion failure modes; and 2) how to remediate cracked earth embankments. In the first section, general information is presented on which soils are most susceptible to cracking and which pose the greatest risk for fa...
