Experiment: So schnell kann Hochwasser zur Gefahr werden | Quarks

Rushing water, triggered, for example, by flooding, has extreme force. It's easily underestimated and can even be life-threatening. Quarks conducts a flood experiment and, together with DLRG current rescuers, demonstrates how helpless one is exposed to flash floods during floods. The test, of course, doesn't take place in a real river, but in an artificially created floodwater in a canoe park. Here, the rapidity of the current and the depth of the floodwater can be precisely determined. At two meters per second and 40 centimeters deep, the floodwater isn't yet dangerous for an adult, but what about at higher speeds or in deeper water? Is it still possible to escape from such a body of water? Authors: Ulrich Grünewald, Daniel Haase --- Thanks for watching! Did you like the video?
