St. Francis Dam Failure STEM Case Study

Investigate one of the worst civil engineering disasters in American history with this comprehensive, no-prep 6-page printable STEM Case Study Packet! Designed specifically for middle and high school classrooms, this multi-day unit provides an immersive, highly informative look at the catastrophic 1928 St. Francis Dam Failure. By combining fluid mechanics, geology, forensic investigation, applied mathematics, and regulatory ethics, this resource transforms a landmark civil failure into a rich, interactive learning experience.

Throughout this unit, students explore critical secondary STEM concepts—including hydrostatic water pressure physics, geological uplift, pore-pressure piping erosion, concrete gravity dam mechanics, and civil safety regulation—in an accessible, highly engaging format.

What’s Included in this 6-Page Deep-Dive Packet:

• Page 1: Historical Case Study & Technical Breakdown

  Features a detailed historical narrative of the March 12, 1928 disaster and William Mulholland's aqueduct expansion project. Students examine concrete gravity dam mechanics, fault-line piping erosion, and Sespe conglomerate rock dissolution before answering targeted comprehension check questions.

• Page 2: Day in the Life Scenario Challenge

  Students step into the shoes of a Lead Forensic Hydraulic Engineer on the morning after the collapse, March 13, 1928. In this realistic roleplay assignment, they analyze flood telemetry logs, investigate abutment leakage diagnostics, and trace emergency dam failure indicators.

• Page 3: Hands-On Unplugged Simulation & Applied Math

  Brings hydraulic engineering math into the classroom with clear, step-by-step problem sets. Students compute total hydrostatic water force against dam gravity sliding resistance, calculate uplift pressure ratios, and evaluate reservoir water volume discharge rates.

• Page 4: Engineering Ethics & Workplace Dilemma

  Explores professional liability and regulatory oversight. Students evaluate the consequences of dismissing warning leaks, relying solely on visual inspections without geological core testing, hubris in engineering authority, and the eventual creation of independent state dam safety laws.

• Page 5: Redesign Brief & Innovation Lab

  A creative blueprinting challenge where students act as modern civil engineers designing "St. Francis Dam Replacement V-2." Applying hydro-structural principles, they incorporate deep foundation cut-off walls, internal drainage galleries, grout curtain seals, and real-time piezometer pressure sensors.

• Page 6: Teacher Answer Key & Scoring Rubric

  Includes complete, step-by-step solutions for all narrative comprehension questions and mathematical calculations, along with a clear 10-point grading rubric to streamline assessment for the design blueprint assignment.
