On-Demand Webinar: Time History Evaluation of Piezometers 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 can not reproduce the rate change of piezometers with reservoir/river changes.  Engineers call is flat or aggressive response. This webinar will provide numerous tools for trying to understand real-time piezometer respond at different locations in a dam.

Key Takeaways:

• Review the fundamentals of seepage, focusing only on the practical information needed.
• Study the effects of early and late sand layer blockage.
• Understand how seepage leakage impacts the seepage process.
• Learn about and how to utilize the improved Reservoir-Piezometer projection technique, also known as RP plots.
• Comprehensively compare piezometers at different elevations using RP plots.
• Enhance standalone piezometers in sand-based environments with quickly performed CPT soundings.
• Gain knowledge about backward piping in relation to detailed seepage and how RP plots can be utilized.
• Review detailed descriptions of seepage failures to understand the process from initiation to failure.
