Most of the largest dams in the world have gated spillways with whole teams of staff dedicated to their operation. But it’s still a challenge, especially for small owners like cities. So there is another option, kind of in between controlled and uncontrolled spillways, and its use is growing worldwide.

Errata: At 9:00, the left column of calculations is incorrectly labeled "SI." It should be imperial. Whoops!

Just as all materials have a mostly linear relationship between temperature change and length change, all materials also have a similar relationship between stress and change in length (often called strain). And this is part of the secret to continuous welded rail: restrained thermal expansion. You can overcome one with the other.

Comparing costs and safety is an enormous challenge. On one side, you have dollars, and on the other, you have people. Sometimes you need a conversion factor. It sounds morbid, but it’s necessary for good decision-making to put a dollar price on the value of a human life.

People use water at more or less a constant rate and yet, mother nature supplies it in unpredictable sloshes of rain or snow that can change with the seasons and often have considerable dry periods between them. If the sloshes get too far apart, we call it a drought. And at least one study has estimated that the past two decades have been the driest period in more than a thousand years for the southwestern United States, leading to a so-called “mega-drought.” (Source: https://www.npr.org/2022/02/14/1080302434/study-finds-western-megadrought-is-the-worst-in-1-200-years)

On the evening of Friday, February 3, 2023, 38 of 149 cars of a Norfolk Southern Railway freight train derailed in East Palestine, Ohio. Five of the derailed cars were carrying vinyl chloride, a hazardous material that built up pressure in the resulting fires, eventually leading Norfolk Southern to vent and burn it in a bid to prevent an explosion. The ensuing fireball and cloud brought the normally unseen process of hazardous cargo transportation into a single chilling view, and the event became a lightning rod of controversy over rail industry regulations, federal involvement in chemical spills, and much more.

The grid is a little bit of a house of cards. It’s not necessarily flimsy, but if the whole thing gets knocked down, you have to rebuild it one card at a time and from the ground up. Restoring power after a major blackout is one of the most high stakes operations you can imagine. The consequences of messing it up are enormous, but there’s no way to practice a real-life scenario. It seems as simple as flipping a switch, but restoring power is more complicated than you might think.

Making a structure last as long as possible before it needs to be replaced isn’t just good stewardship of resources. It’s a way to keep the public safe and prevent environmental disasters too. Corrosion is one of the number one ways that infrastructure deteriorates over time, so cathodic protection systems are an essential tool for keeping the constructed environment safe and sound.

Correction: The Carlsbad plant produces 50 MGD, which is roughly 190,000 cubic meters per day (not 23,000 as stated).

It might surprise you to learn that there are more than 18,000 desalination plants operating across the globe. But, those plants provide less than a percent of global water needs even though they consume a quarter of all the energy used by the water industry. The oceans are a nearly unlimited resource of water with this seemingly trivial caveat, which is that the water is just a little bit salty. It’s totally understandable to wonder why that little bit of salt is such an enormous obstacle.

Errata:
At 10:40, the meter is set to resistance (not voltage). Since current is constant, it is also an indication of differences in voltage, but the script should have been a little clearer.

Current doesn’t flow to the ground; it flows through the ground and back up. If there is electricity moving into the ground from an energized conductor, go back to the source of that conductor and see what’s happening. For the grid, it’s probably a transformer or electrical generator, in either case, a simple coil of wire. And, the electrical current flowing out of the coil has to be equal to the electrical current flowing into it, whether that current is coming from one of the other phases, a neutral line, or an electrode buried in the ground.

Both Florida DOT and Superior Construction were contacted for comment on this story. FDOT declined to comment, and Superior Construction did not respond to multiple emails.

Barrier islands are critical to protecting mainland coasts by absorbing wave energy and bearing the brunt of storms. But development on the islands negates that critical purpose. That doesn’t mean the community doesn’t belong there. But it does obligate the planners and engineers involved in rebuilding to be thoughtful about the impacts hurricanes can have and how infrastructure can be made more resilient to them in the future.

Tanker truck fires at bridges happen rarely, but when they do, they often lead to a collapse or at least a replacement. How do engineers characterize bridge fires, and should bridges be better protected against them?
