The HydroSciences Montpellier laboratory has developed the Environmental Information System on Water Resources and their Modelling (SIEREM) for the whole of Africa.
It is the most important Environmental Information System on the African continent with 13,000 measuring stations, 33,000 time series, i.e. more than 117 million records, for the period 1837 to 2015.
The hydro-climatological data are coupled with spatialized data: 201 watershed contours, 2962 rivers. The recovery of hydrological archives has enabled SIEREM to be enriched. More than 1342 photos have been collected in 391 geo-referenced albums. The SIEREM site allows free access to all this information except for the raw measurement data which are the property of the African national services.
