Heavy rain fall event

As predicted last weekend heavy rain fall occured in eastern Austria. Also the HOAL was affected by high precipitation rates.

In 30 hours around 60mm of rainfall occured and this led to a discharge rise at the catchment outlet from 1,5 l/s to over 40,0 l/s. Compared to the mean rates (820mm/year mean annual precipitation; 4,0 l/s mean annual runoff) this was a middle high event which we were happy to catch with our sensors and installations. Several water samples were taken automatically and are currently under analysis for chemical and physical parameters in the laboratory.
