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...

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...

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 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...

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...

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, 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...

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...

Participants will gain a practical knowledge of methods for simulation of runoff from storm rainfall. The methods covered relate to the processing of historical and hypothetical (design-storm) rainfall data; estimation of losses (infiltration); transformation of rainfall excess to direct runoff with unit hydrographs; routing of flood waves; calibration of model parameters; and modeling of runoff from watersheds. Experience will be gained in ap...

This introductory course is designed to be a participatory, interactive workshop, which will cover the basic elements required to understand and evaluate seepage-related issues for earth dams. The course begins with providing an understanding of why seepage mechanisms in earth dams are important to dam safety. Information on seepage mechanics, including permeability and erodibility will then be presented. The presentations will then progress t...
