Join us on Tuesday, January 12, 2027, from 12:00 PM to 2:00 PM Eastern for Uplift from Stagnation Pressure and Seepage Through Joints in Concrete Spillway Slabs. This webinar provides attendees with a deep understanding of historical and modern developments in hydraulic jacking, including past failures and early, recent, and cutting-edge physical and numerical modeling. 

Learning objectives attendees will receive from this webinar:

• Explain how high-energy spillway flow can create uplift pressures and seepage that may lead to slab failure.
• Describe how offset joint geometry influences the development of uplift pressure.
• Summarize why early uplift pressure methods were uncertain and how boundary layer velocity profiles improve predictions.
• Estimate flow rates entering offset joints.
• Apply laboratory findings to practical spillway joint evaluation and design.
• Identify lessons from laboratory testing for addressing deteriorated spillway joints.
• Assess the benefits and limitations of foundation drainage systems for reducing uplift pressure.
