@architectzvideos: This hole can swallow 50,000 cubic feet of water per second 🌪️ It’s called a “Morning Glory Spillway” — and it’s basically a giant drain plug for dams. When the reservoir gets too full, water pours into this funnel and disappears... straight down a 180-meter vertical shaft, through a curved tunnel, and out the other side of the dam. No pumps. No electricity. Just pure gravity doing the work of preventing a catastrophic flood. Would you swim near one of these? 👀 #MorningGlorySpillway #EngineeringMarvels #Oddlysatisfying #HowItWorks #DamEngineering
