Introduction & Overview of Rock Scour - Four Part Series
- Registration Closed
Description
One of the many lessons learned from the 2017 Oroville spillway incidents was there is a poor understanding in the industry of assessing the erodibility (scour) of earthen (soil and rock) spillway chutes. There appears to be a general lack of knowledge in the information, tools, methods, and interpretation of the erodibility of earthen materials. This workshop will provide the knowledge and understanding of what information is needed for a scour assessment, what current tools and methods are available to perform a scour assessment, and provide case histories illustrating the use and interpretation of the results of scour analyses.
This webinar will be limited to the characterization, evaluation, analysis, and remediation of erodibility of rock scour. Erodibility of soils will not be covered.
Objectives
This webinar will provide a general overview for the understanding of the factors that influence the erodibility of rock.
Target Audience
Novice to seasoned professionals will all benefit from this webinar. All sub-disciplines of civil engineering and engineering geology should attend.

Principal
George W. Annandale, Inc.
Dr. Annandale has more than 40 years of experience as a civil engineer specializing in water resources engineering. He offers services in the field of fluvial hydraulics, design and engineering; reservoir and water supply management; and hydrology and hydraulics. He has published numerous peer-reviewed papers and is author, co-author and contributing author to eight books on sedimentation and scour. He was named by International Water Power and Dam Construction as one of 20 engineers who made a significant global contribution to dam engineering at commencement of the 21st century. Dr. Annandale is known for the development of the Erodibility Index Method that can be used to determine the erodibility of any earth material, including rock. The method has been accepted by the engineering profession, is used globally for design and safety assessment of infrastructure and is included in federal and state manuals and guidelines. The method is contained in guidelines by FERC, US Army Corps of Engineers, US Bureau of Reclamation, US Federal Highway Administration, Australian Dam Safety Authority, Electricite de France, French Gravity Dam Guidelines, and others. He authored the book "Scour Technology", published by McGraw-Hill in 2006, which has become a standard reference in this field of specialization. Dr. Annandale consults internationally and has worked on projects in more than 25 countries.
