How the Edenville Dam Failed

Back in May 2020, the Edenville Dam in Michigan failed dramatically, releasing flood waters that destroyed a downstream dam and caused millions of dollars of damage. In this Practical Engineering video, Grady deconstructs the accident, based on an interim report from the forensic team charged with investigating the failure. Along the way, he explains common causes of dam failures, what made the Edenville failure unusual, and how engineers build modern earthen dams to avoid this older design’s flaws.

The Best of FYFD 2024

Welcome to another year and another look back at FYFD’s most popular posts. (You can find previous editions, too, for 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016, 2015, and 2014. Whew, that’s a lot!) Here are some of 2024’s most popular topics:

• The Taum Sauk Dam Failure and Its Legacy
• Stretching Ant Rafts
• Gigapixel Supernova
• Feynman’s Sprinkler Solved
• Calming the Waves
• “Dew Point” Deposits Droplets

The Taum Sauk Dam Failure and Its Legacy

Managing an electrical grid is all about balancing the electricity that plants can supply with the instantaneous demands of consumers. If there’s more power available than people need, it needs to get stored somehow. And for decades, the best way to store that excess supply has been in hydroelectric reservoirs like at the Taum Sauk Dam. These facilities pump water to a reservoir at a higher elevation when there’s extra electrical power available, and, when more power is needed, release that water to run through hydroturbines.

But storing water atop a mountain comes with unusual challenges for dam, and the 2005 failure of the Taum Sauk Dam facility highlights some important lessons for engineers. As Grady lays out in this Practical Engineering video, there was no single mistake that led directly to the dam’s failure. Instead, post-collapse investigations found a series of seemingly minor issues that, together, led to catastrophe. It’s well worth watching, especially for engineers; we could all use an occasional reminder that a “quick stopgap measure” isn’t enough. (Video and image credit: Practical Engineering)

There's an oxbow of the Blue Earth river in that area and I imagine it's in the back of people's minds to try to avoid a cutoff.

Good, historic footage in this piece.

Kakhovka Dam explosion, flooding, and nuclear power plant video 'splainer

The blancolirio channel on YouTube has an excellent explainer and analysis of the as well as the impacts on the Zaproizhzhia nuclear power plant (ZNPP) upstream of the dam.

Flooding isn't the problem there, but maintaining a supply of cooling water for the plant is. Note that ZNPP which is in cold shutdown so is NOT operating is not presently a major risk. Though it does remain in Russian control.

Blancolirio is a commercial airline pilot who ran an excellent series on an earlier dam incident covering the Oroville Reservoir in northern California following major damage to its spillway in 2017, and subsequent repairs and refurbishment. Very high signal/noise, strongly recommended.
