WinDAM - Overtopping and Internal Erosion for Earthen Embankments: Download

WinDAM software estimates the erosion and breach outflows from overtopping flows and internal erosion flows affecting earthen embankments. This webinar will provide an overview of the WinDAM model and the various inputs needed. The webinar will also cover output from WinDAM. The webinar will target users and designers more than researchers.

Key Takeaways:

  • How could overtopping affect my earthen dam?
  • How could internal erosion breach my earthen dam?
  • How do I operate WinDAM software?
  • What data do I need to put in a WinDAM model?
  • What results/output does WinDAM software provide?
