Webinar: Overtopping Protection Systems - Part II

This event qualifies for 2 PDH

This is the second of a two-part series on overtopping protection systems for embankment and concrete dams (Register for Intro to Overtopping Protection Systems). Many dams today have insufficient spillway capacity and may be overtopped during large floods below the regulatory requirement. In recent years, dam overtopping protection has become increasingly popular as a means to provide additional flood release capacity when more conventional methods such as increasing spillway discharge capacity or reservoir storage are cost prohibitive or impractical. This course will present the process of evaluating protections systems for use in spillway applications. A summary of determining appropriate project hydraulic conditions will be followed by a brief history of prototype research conducted on multiple types of protecting technologies. Results of these tests will be presented in support of design methodologies where new methods for determining project FOS and numerically evaluating hydraulic jump system performance will be recommended. Procedures outlined in NRCS NEH Part 628 Chapter 54 “Articulated Concrete Block Armored Spillways” will be presented in an effort to show a standardized evaluation approach whereby permitting evaluation of multiple protection system technologies. The presentation will conclude with an example of a design application.

Speaker and Presenter Information


Chris Thornton
Director of the Engineering Center and Hydraulics Laboratory
Colorado State University

Chris is the Director of the Engineering Center and Hydraulics Laboratory at Colorado State University.  He received his PhD in Hydraulics at Colorado State University and is a registered Professional Engineer in the state of Colorado.  He has over 20 years of experience in conducting hydraulic model studies and has specialized in steep slope, high energy, supercritical flow conditions and performing prototype performance tests on protective techniques.  Chris and his team have recently developed tools to permit the interpretation and evaluation of overtopping hydraulics and protection systems associated with spillway and stilling basin design.  Dr. Thornton teaches the Senior Design series for the graduating Civil and Environmental Engineering students and has authored and co-authored numerous papers and reports in the area of open channel hydraulics.
