ASDSO's Journal of Dam Safety, first published in Spring 2003, provides opportunities to share lessons learned and technology related to dams and levees. The Journal is published quarterly in March, June, September, and December.
Each issue includes technical and/or policy articles (typically three), a training calendar, and a summary of recent dam safety news and events.
Subscription to the Journal of Dam Safety is one benefit of ASDSO membership. Non-members can subscribe by calling 855-228-9732 or emailing email@example.com.
Full issues and individual articles from the Journal (ISSN 1944-9836) are available through the ASDSO Bookstore.

A New Instrumented Becker Penetration Test (iBPT) for Improved Characterization of Gravelly Deposits Within and Underlying Dams
By: Jason DeJong, Ph.D.; Mason Ghafghazi, Ph.D., PEng.; and Alexander Sturm, University of California, Davis; Richard J. Armstrong, Ph.D., P.E., CA Dept of Water Resources; Adam Perez, P.E.; and Craig A. Davis, Ph.D., P.E., G.E., Los Angeles Dept of Water and Power
A new, instrumented Becker Penetrometer (iBPT) has been developed to provide measurements of energy directly at the drill string tip. Details of this new system, including the hardware, its operation, data processing, and example results are described. An overview of the fieldwork completed to date at two project sites is summarized. Finally, the methodology developed to estimate equivalent SPT N_60 blow counts using the new iBPT method is presented.
The Great Flood of 1913 and the First Hundred Years of the Miami Conservancy District
By: Kurt A. Rinehart, P.E., Miami Conservancy District
One hundred years ago the citizens and community leaders in Dayton and neighboring communities in southwestern Ohio were venturing into the unknown: planning a flood protection system unlike anything that had been tried anywhere. This paper follows the catastrophic event that caused them to take such an action, the project that resulted, and how that project has fared after its first 100 years.
Behavior of Embankement Dams during Earthquake
By: James R. Swaisgood, P.E., C.P.G., Consultant
An evaluation of case histories of the deformation of embankment dams due to earthquake has been in progress since 1990 with two objectives in mind:
• Providing a tool for immediate assessment of a structure that has undergone seismic loading, and
• Creating a method for checking the results of complex deformation analyses against actual, historic dam behavior during earthquake.
The findings from these on-going empirical studies were last presented ten years ago. Since that time, the research has continued, increasing the database by nearly 20 percent. This paper presents the results of the extended examination and re-analyses of the entire database.
