Join us on Tuesday, May 13 from 12:00 PM - 2:00 PM Eastern for The South Fork Dam Breach and Johnstown Flood of 1889: A Civil and Dam Engineering History of the USA’s Deadliest Dam Failure. The 1889 breach of the South Fork Dam, which caused the infamous “Johnstown Flood,” remains the deadliest dam failure in US history. The Commonwealth of Pennsylvania built the dam in the mid-1800s as part of a cross-state transportation ne...

For Concrete Dams, knowledge is an important characteristic regarding design and analysis. When there is a reduction in the level of knowledge, then there is usually a corresponding increase in conservativeness. When conservative assumptions increase, then costs will increase. Therefore, it is easy to see why knowledge is important. This seminar has been developed to educate professionals in the engineering practice of concrete dam design and...

Join us on Tuesday, June 10 from 12:00 PM - 2:00 PM Eastern for The Use of Void Ratio (e) in Earth Dams. Void ratio (e) is a term used extensively in soil mechanics. It is a fundamental ratio that quantifies the changes in volume taking place in a soil mass. Earthen dams are constructed with soils that hold back water over a long period of time, even though they are made of pervious materials. The embankment and foundation soils may differ in...

The objective of this course will be to provide a comprehensive presentation of the significant principles and concepts of soil mechanics to the participants. The material will be presented with emphasis on the basic soil mechanics principles prerequisite to further study for the design or rehabilitation of earth embankment dams. This is a basic-level course intended as an introduction for those with minimal to moderate knowledge or experience...

Join us on Tuesday, July 8 from 12:00 PM - 2:00 PM Eastern for Piezometric Data Evaluation for Seepage Characterization of Levees and Earth Dams. The webinar will show how to evaluate the time series of piezometric data for dams and levees. Theory tells us that piezometers should respond in relationship to river/reservoir levels (in a linear rate) – but it never does. Seepage computer models cannot reproduce the rate change of piezometer...

This course provides an introduction of HEC-RAS with applications to dam safety. The course provides a hands-on opportunity to use the program and resolve specific questions. The objective of this course is to review the basic principles of open channel hydraulics as they relate to the natural stream environment with application to dam safety. Bridges, culverts, and in-line structures will be discussed and both steady and unsteady flow modelin...

This course will be an interactive seminar that provides a well-blended mixture of lecture presentations covering various design disciplines along with several strategically designed hands-on exercises that provide interaction among participants. The exercises will be developed to include review of documents for a dam rehabilitation project to provide experience for the novice dam safety engineer with design review. This course has been develo...

The objective of this course is to provide instruction on the general subject of earthquake engineering of embankment dams. The course will begin with a historical perspective on dam performance during earthquakes and an overview of basic concepts about earthquakes. The course will then progressively address more specialized subjects including a) evaluation of seismic hazard and characterization of earthquake motions for dam design, b) field i...

This is an interactive seminar focused on the practical use and advantages of two-dimensional flow capabilities in HEC-RAS, with emphasis on applications for the dam safety industry. The course will maintain a balance between lecture-style presentations on model theory and hands-on workshop sessions for practical examples. Topics will include applications and benefits of HEC-RAS 2D modeling; RAS Mapper and terrain preparation; executing 2D mod...

Join us on Tuesday, September 9 from 12:00 PM - 2:00 PM Eastern for Getting Ahead of the Storm: Building Capacity to Respond to Large-Scale Weather-Related Dam Impacts. This webinar will discuss the lessons and expertise gained from rebuilding a state dam safety program from state dam safety program officials and emergency managers almost 10 years after a historic rainfall event that had impacts statewide and caused the failure of 50 state-reg...
