Discharge, Auradé

The discharge data are presented at (1) mean hourly, (2) mean daily time steps and (3) high frequency data every 10 mn, for the Montoussé stream at the oulet of the AURADE catchment.

For the period 01/10/2004-30/09/2021: to use the data, cite Ponnou-Delaffon et al. (2020) https://doi.org/10.1016/j.ecolind.2019.105894 (see also other references below).
The discharge rating curve associated to the data DOI is as follows:
-if HT <7.5 cm: Q=0.0013*HT
-if HT >7.5 cm: Q=0.0003*HT^2-0.0031*HT+0.00161
With Q=Discharge (l/s) and HT= Water level (cm)

For the data series 1/10/2004-04/05/2006 : discharge was estimated from the water level recorded by a mechanical limnigraph (OTT type) and partially filled by the GR4J model (see Perrin, 2008, PhD). From this date onwards, a combination of continuous measurements using an electronic probe (YSI 6920) and a mechanical hydrograph (OTT type) was used. For all series, a mixed method of loess over 24-12-6-3 and 1 hour was applied to smooth the data.

For the period 01/10/1983-30/09/2004, the data are available on HydroPortail (France) https://hydro.eaufrance.fr/. Note that at this period the discharge rating curve was Q=2.286*HT^2.27
