Piezometric Data Evaluation for Seepage Characterization of Levees and Earth Dams

Join us for Piezometric Data Evaluation 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 cannot reproduce the rate change of piezometers with reservoir/river changes.  Engineers call it flat, or aggressive, response. This webinar will provide numerous tools for trying to understand real-time piezometer response at different locations in a dam.

Learning objectives attendees will receive from this webinar:

• 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 how to utilize the improved Reservoir-Piezometer projection technique, also known as RP plots.
• Learn to 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.
