This course is a three-day introduction of HEC-RAS and a one-day introduction to HEC-RAS 2D, with applications to dam safety. The three-day introduction course provides hands on opportunity to use the program and resolve specific questions. The objective of this course is to review the principles of open channel hydraulics as they relate to the natural stream environment with application to dam safety. Both steady and unsteady flow modeling wi...

Together Paul Schweiger and Dean Durkee have offered this seminar 13 times in 12 states and it has been attended by more than 800 students. The seminar provides comprehensive instruction in inspection and evaluation techniques for dams. The principles, concepts and procedures taught will be readily adaptable to any organization conducting dam inspections and evaluating their compliance with current design standards. Participants learn about a...

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...

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...

COURSE OBJECTIVES This seminar provides comprehensive instruction in inspection and evaluation techniques for dams. The principles, concepts and procedures taught will be readily adaptable to any organization conducting dam inspections and evaluating their compliance with current design standards. The target audience is state and federal dam owners/regulators, local and private dam owners/operators, consulting engineers and personnel responsib...

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 t...

A large difference between water storage dams versus tailings dams and coal ash impoundments is that these industrial structures are always under construction. This provides the opportunity to optimize design and construction, but places an emphasis on ongoing evaluation and monitoring. This course provides an overview of the unique construction and design components of these facilities. This course will examine a number of recent failures tha...

Hydrologic hazard curves are critical flood loading inputs for dam and levee safety risk assessments. Over the past decade, some Federal agencies have developed and applied new tools and data sets to estimate hydrologic hazard curves, which are graphs of peak flows, volume, or reservoir stages versus Annual Exceedance Probability (AEP). Hydrologic hazard curves provide a full probability distribution for the flood hazard, covering the range of...

The webinar consist of two sessions. Session 1 will be an overview of Geophysical methods applicable to dams and levees, how theory behind the methodologies, and the strengths and limitations of each method. This session will also cover what additional investigations, such as drilling, are necessary to calibrate the geophysical data in order to provide a holistic evaluation of the subsurface conditions and how these conditions can affect dam a...
