River flow monitoring in summer

05 Septembre 2017
Sécheresse

Water levels in rivers drop during the summer time, and the rivers can sometimes dry up altogether. This natural phenomenon called low-flow level is often accentuated by water needs such as drinking water supply, irrigation or watering parks & gardens, at a time when water resources are scarce. How and when do these low-flow levels occur during the summer ? Why should this be monitored and how ? What variation can be observed over time ? Field observations between 2012 and 2016 show that August 2012 and September 2016 were the months where the most rivers dried up, with significant variation across France.
