중국 393억톤이 10시간이면 우한에 도달합니다

In 1975, a single dam collapsed, killing 240,000 people. Today, China has dams holding 58 times that amount of water. If they were to collapse, the water would reach Yichang in 30 minutes and Wuhan in 10 hours. 39.3 billion tons of water rest upon the lives of 400 million people. We examine the structure of how this water spreads across time and distance, and why concrete gravity dams have never completely collapsed to date. Topics covered in this video 👇 ✅ Comparison of the scale of the 1975 Banqiao Dam collapse and the 39.3 billion-ton Three Gorges Dam ✅ Scenarios for downstream arrival times: 30 minutes to Yichang, 10 hours to Wuhan, and several days to Shanghai ✅ Why 47 percent of the Yangtze River Economic Belt's GDP depends on this waterway ✅ Why concrete gravity dams have never completely collapsed in history ✅ Cracks, earthquakes, and landslides: Risk variables that are still accumulating ✅ The existence of Chongqing, a city excluded from emergency response systems 🔔 Subscribe to World Economy Focus to be the first to discover the hidden economic structures of countries around the world Subscribing and liking this video is a great help in creating high-quality content. 📌 Fact Check and Data Sources All figures and facts in this video have been verified based on the official sources below.
