Manual groundwater level for some wells and hourly groundwater measurements for others equipped with a logger. The water table level values are expressed from the soil surface.

Rainfall measurements collected since 1999 by recording raingauges to complement and densify the Oueme (CL.Rain_O) network, in particular over the Donga basin. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.

Data of type hydrology-hydrogeology measured on Le Theluet basin within the framework of the KARST DE LA CRAIE observatory, that is part of the KARST observatory network. The KARST observatory network aims to strengthen knowledge-sharing and to promote cross-disciplinary research on karst systems, in the framework of the OZCAR Critical Zone network Research Infrastructure. Data consist in 13 time series on 5 station(s). The measured parameters are: Discharge (m3/s), Flow velocity (m/s), Water level (m), Water level (mm). Measurements start on 01-12-1999 and end on 04-04-2017

Rainfall measurements collected since 1999 (Long Observation Period) by recording raingauges over the Oueme basin (1.4-2.9°E; 8.9-10.2°N). It was designed for a homogeneous coverage of the basin with 29 gages. NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.

Rainfall measurements collected since 1999 by 5 recording raingauges deployed over the East Niger (Tillaberi, Konni, Tahoua, Maradi, Zinder). NB: Negative values are missing values. Negative value other than -9999.9 is missing value estimated from the bucket. For a period with such missing data, although the same value is indicated for each timestep, the value applies to the whole time period.

Data of type chemistry measured on Le Theluet basin within the framework of the KARST DE LA CRAIE observatory, that is part of the KARST observatory network. The KARST observatory network aims to strengthen knowledge-sharing and to promote cross-disciplinary research on karst systems, in the framework of the OZCAR Critical Zone network Research Infrastructure. Data consist in 20 time series on 5 station(s). The measured parameters are: Conductivity (mS/cm), Conductivity (µS/cm), Turbidity (NTU), Water temperature (°C). Measurements start on 21-09-1999 and end on 08-11-2013
