Lessons from a Dam Failure

  title={Lessons from a Dam Failure},
  author={Jonathan P. Evans and Verena A. Gill},
The IVEX Dam (Chagrin River, northeastern Ohio) failed catastrophically on 13 August 1994, releasing 38,000 m (about 10 million gallons) of impounded water and sediment. This event was triggered by a 70-year rainfall event (13.54 cm of rainfall within 24-hours), resulting in flows 1.9 m above the top of the spillway and impinging on the top of the dam. The failure was the result of seepage piping at the toe of the dam, near the masonry spillway-earthen dam contact. Eyewitnesses reported that… CONTINUE READING
