Webinar: Introduction to Addressing Ina...
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...
Webinar: Analysis of Concrete Arch Dams
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...
Webinar: Re-examination of the 2004 Fai...
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...
Webinar: Why Embankments Crack and How...
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...
Seepage Through Earthen Dams
Join us at Conference Chicago at University Center, June 12-14, for Seepage Through Earthen Dams. This 2.5-day introductory course is designed to be a participatory, interactive workshop, which will cover the basic elements required to understand and evaluate seepage-related issues for earth dams. The first day begins with providing an understanding of why seepage mechanisms in earth dams are important to dam safety. Discussions of basic princ...
Fundamentals of Reinforced Concrete Des...
Join us May 15-17 at the Desert Willow Conference Center in Phoenix, AZ. 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 ex...
Stability Analysis of Embankment Dams
This course provides broad coverage of stability analysis for embankment dams. Topics addressed in the course include soil stress-strain behavior, shear strength selection, field and laboratory testing methods, slope stability analysis methods, slope stability analysis loading cases, seepage as related to stability analysis, and stability rehabilitation methods. The course includes several exercises to reinforce the information presented in le...
USDA BioPreferred Training Program -
Designed especially for federal technical staff and federal contractors with responsibilities for facility operations and maintenance, this course will familiarize you with categories of biobased products relevant to the O&M function, resources helpful in the selection of biobased products, and ideas for overcoming obstacles to the adoption of biobased products. Course Objectives After completing this module, you will be able to: list biob...
Sensitive Compartmented Information Fac...
After attending this unclassified Workshop, students will be able to oversee design and construction of a sensitive compartmented information facility (SCIF) which meets official government requirements for a secure area where classified information is handled. The stringent physical security requirements; such as, access control systems, thickness of doors, the strength of concrete and the use of alarms, and acoustical controls which prevent...
Conduits, Gates and Valves
Course Objectives The objective of this course is to provide a general understanding of conduits, valves and gates in the context of the operation, maintenance and design of dams and dam safety. Emphasis will be placed on issues related to the design, construction, and performance of conduits, values, and gates types commonly used at dams. Case histories and practical exercises will be used to enhance learning of the purposes and features of c...
