More than 50% of the world’s river network is made of temporary or intermittent rivers: those which, during a certain time of the year, mainly summer, present dry riverbeds or some isolated ponds. These rivers show high variability, both spatially and temporally, which makes it impossible for the same tools used to gauge the state of health of permanent rivers to be applied to them.
