It has been raining for days; from the late morning of July 14, 2021, it has been pouring without interruption. In the afternoon, it becomes clear that it should be about five times more than the “flood of the century” of the Ahr river compared to 2016. On average, about 8 m3/s flow in the Ahr river annually; now it was about 1200 m3/s, thus about 150 times more.
