Asphalt has been used to impound both liquids because of its longevity, strength, impermeability, and flexibility. This webinar will provide an overview of the use of asphalt in dams and makes the case for considering its use when appropriate.

The webinar will touch on Risk Informed Decision-making 101, consequence estimation, decisions following risk analyses and assessment, and routine risk management and measurement.

Learn about data acquisition from the field, and general considerations for efficient data collection/transfer/storage. Once that data is collected, visualization is key, and there will be discussions on how to transform that data into useable information for evaluation and communication.

This webinar will provide an overview of developments in seismic hazard assessment in the Central and Eastern United States (CEUS), with a focus on their applicability to dam sites.

This presentation will describe newly developed predictive models for earthquake-induced slope displacements based on finite element simulations.

This webinar will review an approach to evaluating systems and human factors within a semi-quantitative risk assessment.

This webinar will cover topics like climate change and flood hazards, spillway erosion, CFD modeling, and spillway design.

Learn how InSAR can be useful for monitoring dam safety.

This four-part webinar will discuss best practices for planning, implementing, and managing a dam safety program. You will get a general overview of the role of instrumentation in project performance monitoring and the factors that influence the accuracy, reliability, and use of dam instrumentation data.

This webinar focuses on how to analyze the data from instrumentation to understand project performance. It highlights common errors and misunderstandings to be avoided as well as how to identify concerning data.

The importance of maintaining an engineer of record and their responsibilities will be explained with consideration to recently promulgated requirements and guidance.

In this talk Robb Moss will give an overview of our GEER efforts, bring the lessons learned back to the US, and will give specific attention to the many earthdams that exhibited different levels of performance.

This webinar will explain how a phased approach offers owners benefits from a cost and operational perspective along with limiting the amount of destructive examination that may be required to better understand the spillway and its subsurface conditions.

Topics Covered • Low head dams – defined, purposes, issues • What can be done – rehab, removal, signage • Our task group work and involvement Learning objective: Learn how to participate in creating a National Inventory of Low-head Dams Target audience: Dam Safety Directors, staff, and those in industry who support public safety efforts

This presentation will discuss the effects of subsurface heterography on liquefication-induced ground deformation
