Spillway Erodibility Investigation & Analysis

This seminar offers an in-depth understanding of earthen spillway design and erosion issues critical for engineers and professionals across the dam safety community. The seminar includes engaging sessions that delve into the mechanics and dynamics of spillway erosion, fostering a comprehensive grasp of analysis, investigation, and mitigation strategies. Participants will benefit from expert-led discussions, interactive presentations, and case study reviews covering key topics such as understanding erosion mechanisms, determining critical erodibility parameters, conducting a field evaluation, O&M considerations, and analyzing earthen spillways with a variety of tools, like the NRCS WinDAM C software. Additionally, the course features hands-on activities and real-world scenarios to allow participants to immediately apply their skills during the course in a collaborative learning environment.

Learning objectives attendees will receive from this course:

• Understand relevant factors associated with soil and rock erosion mechanisms.
• Learn about contributing features that lead to unlined spillway erodibility failure modes.
• Learn how to apply field investigation procedures, including visual observations and subsurface exploration.
• Understand considerations for earth spillway design, operation, and maintenance, as well as erosion mitigation strategies.
• Learn about the application of erodibility analysis tools such as the NRCS WinDAM C software, including the development of key erodibility parameters.

Attendance Policy:  

Please note that this course is a multi-day technical seminar even though it is being delivered in a virtual format.  Seminars require attendees to be present each day and to participate in the interactive course.  Failure to attend each day may limit access to future components and completion of the course.  Only registered attendees can access the seminar, materials, and recordings.  Professional development credits will only be recognized for the registered attendee.  Additional people should not be sitting in the course.

Virtual Meeting Requirements: 

For this virtual course, you will need a computer, microphone, webcam, and internet connection.  We will use the ZOOM Meeting platform along with the ASDSO Learning Center.  If you do not have the ZOOM Meeting application or cannot download it, you can use the web browser version.  More details will be sent to attendees after registering.
