This Spillway Failed On Purpose

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.

How Earthquake Bearings Work

💾

An overview of seismic base isolation for buildings

Earthquakes are such a challenge in engineering: unpredictable both in time and intensity. But I love this solution of base isolation because it’s so intuitive. It’s something my five-year-old would come up with: just put a suspension system on a building.

Do Retention Ponds Actually Work?

💾

An overview of the engineering behind stormwater ponds

Errata: 5 acres is about 2 hectares. Sorry for the conversion error!

Part park, part plumbing, mostly hiding in plain sight, they are often carefully tuned pieces of infrastructure that help keep the city’s head above water.
