Last Friday, 08-Jun-2018, we recorded a heavy rain event in Dübendorf. In parallel, precipitation and the level of the River Chriesbach were recorded. In only half an hour an amount of 30 millimeter rainfall has been recorded. Nearby river levels raised by1 meter in only 1.5 hours and flooded the walkways!
All measurements realized with our rain gauge and ultrasonic level meter sending data over LoRaWAN to our cloud infrastructure. Precipitation data provided by Eawag (absolute rain depths are still subject to verification).
