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.

Performance Based Testing of Large Concrete Dams
By Ziyad Duron, Joshua Edelman, Madeline Goldkamp, Peter Orme and Tamara Savage, Harvey Mudd College
Summary of a new field testing technique that provides performance indicators of dams under seismic loading.
Downstream Effects Resulting from the Operation of the Pompton Lake Dam Floodgates
By Arthur C. Miller, Brian Cahill and Michael Mak, AECOM; and Russell Ray and John Moyle, NJ Department of Environmental Protection
The focus of this study is the Pompton River Basin, located in the larger Passaic River Watershed, which includes areas of northeastern New Jersey and southeastern New York. NJDEP retained AECOM to develop a hydraulic computer model to simulate the downstream impacts resulting from the operation of the Pompton Lakes Dam Floodgate Facility.
Critical Horizontal Seepage Gradients
By Timothy O'Leary, Noah D. Vroman, Carmen Williams and Mark Pabst, U.S. Army Corps of Engineers
This paper summarizes the errors in the previously published equation by USACE, in Al-Hussaini, Wahl, Peters, and Holmes (1997) and subsequently in FEMA (2011), for the critical horizontal exit gradient and provides suggested approaches to evaluate the hydraulic conditions for the initiation and progression of backward erosion piping.
Monitoring 11,800 Watershed Dams Using the Web-Based DamWatch® System
By James Caldwell, OK Conservation Commission; Joseph Scannel, USEngineering Solutions Corp.; and Noller Herbert, USDA-NRCS
This paper highlights the efforts to gather and upload thousands of files of electronically scanned documents, develop shape files for the dam drainage areas and 1,300 project boundaries, compute the rainfall alert thresholds for each of the dams, enroll initial users, provide training, and deploy the system. The system should be fully implemented for about 3,000 users in 47 states and one territory by Fall 2013.
