Short Course #1
SCOUR OF ROCK
Background
The short course provides state-of-the-art insight and offers techniques that can be used to analyze scour of rock downstream of overtopping dams and in plunge pools. Topics that will be covered include assessment of the potential for rock scour, and the maximum depth and rate of scour of rock. Economical solutions to scour problems are often dependent on knowledge of the rate of scour, i.e. whether the maximum extent of scour occurs almost immediately, or whether it is time-dependent. Scour that occurs almost instantaneously may require extensive protection, while scour that is time-dependent and only reaches its full extent after, say, decades, may require only limited protection if at all. The topics covered are based on technological developments in rock scour assessment developed over the past 20 years.
The short course offers instruction on processes leading to scour, and on pragmatic methods to quantify the erosive capacity of water and the erosion resistance of rock, and practical methods for calculating the potential for, extent and rate of scour. The methodologies presented in the short course have been successfully applied in practice and have been validated by making use of scour case studies.
Learning Objectives
The learning objectives are to provide participants with the opportunity to develop:
Insight into scour processes and how flowing water interacts with rock and leads to scour,
The capability to quantify the ability of rock to resist the erosive capacity of water,
The capability to quantify the erosive capacity of water that can lead to scour of rock,
The capability to calculate the potential for, extent and rate of scour of rock.
The methods presented in the short course will be illustrated with case study results.

Instructor
Dr. George Annandale, P.E., D.WRE, F.ASCE, Program Leader at Golder Associates, Inc., has 35 years of experience as a civil engineer specializing in water resources engineering. He 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 internationally for design and safety assessment of infrastructure and is included in federal and state guidelines. He has published approximately 100 peer-reviewed papers and is author, co-author and contributing author to seven books on sedimentation and scour, including the book Scour Technology, published by McGraw-Hill in 2006. He consults nationally and internationally and has worked on projects in the United States of America, Canada, Australia, Turkey, Iceland, Switzerland, Indonesia, Kalimantan, Papua, Sumbawa, the Philippines, Pakistan, Morocco, Kenya, Sri Lanka, South Africa, Malawi, Israel, Colombia, Venezuela, Mexico, Laos and Zaire.
