| Summary: | <p>The temporal and spatial dynamics of streamflow presence
and absence is considered vital information to many hydrological and
ecological studies. Measuring the duration of active streamflow and dry
periods in the channel allows us to classify the degree of intermittency of
streams. We used different sensing techniques including time-lapse imagery,
electric conductivity and stage measurements to generate a combined dataset
of presence and absence of streamflow within various nested sub-catchments
in the Attert catchment, Luxembourg. The first sites of observation were
established in 2013 and successively extended to a total number of 182 in
2016 as part of the project Catchments As Organized Systems (CAOS).
Temporal resolution ranged from 5 to 15 min intervals. Each single
dataset was carefully processed and quality controlled before the time
interval was homogenised to 30 min. The dataset provides valuable
information of the dynamics of a meso-scale stream network in space and
time. This can be used to test and evaluate hydrologic models but also for
the assessment of the intermittent stream ecosystem in the Attert basin. The
dataset presented in this paper is available at the online repository of the
German Research Center for Geosciences (GFZ,
