Continuous monitoring of water levels and flows at all hydrometric stations in the Real Collobrier watershed since 1967.

The rainfall of the Roujan (Hérault) catchment area has been acquired since 1992 through various measuring points on which sensors are positioned on a long-term and continuous basis. The data from these sensors are directly recorded on servers in Montpellier through remote transmission. Verification treatments and possible corrections are applied before the data sets are integrated into the HYSAE database. Through the OMERE data portal accessible from this sheet, the data can be downloaded from an interactive map. In addition to these raw data rainfall records, a so-called "synthetic" time serie is elaborated to provide a complete and uninterrupted chronicle of rainfall data representative for the catchment area..

Drop Size Distribution measured by a OTT Parsivel2 with a timestep of 1 minute at Al�s, at Ecole des Mines, for the period 2012-2020, in CSV.

Precipitation amount measured by a network of 19 raingauges Precis Mecanique (having interdistance of few meters to fews kilometers) with a timestep of 5 minutes and 1h, during the period 2010-2014.

Precipitation amount measured by a network of 19 raingauges Precis Mecanique (having interdistance of few meters to fews kilometers) with a timestep of 5 minutes, 1h and 24h, during the period 2017-2020.

The measurement of rainfall in Kamech catchment (Cap Bon/Tunisia) is operational since 1994 through a network of daily and instantaneous (tipping bucket) rain gauges, some of them being remotely connected to servers in Montpellier. Verification treatments and possible corrections are applied before the data sets are integrated into the HYSAE database. A "synthetic" rainfall dataset derived from these measurements and accessible from the OMERE data portal is elaborated as acomplete and uninterrupted chronicle of rainfall data for the catchment area.
