Surface suspended sediment concentration (in situ and/or satellite-derived)

Automatic measurement of water level converted into flow and electrical conductivity at the outlet of a 1st order catchment along specific vegetation catena (fallow, forest, bush savannah). The catchment is constituted of hillslope and a bas-fond. For small stream, calibration of the stage-discharge relationships is made by stream-gaging surveys using a wading-rod (velocity-area method). A value = 9999 stands for a dry gully.

Surface suspended sediment concentration (in situ and/or satellite-derived)

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.

Surface water global indices

Measurements of meteorological variables. The sensors are attached to a 2m hight mast, the wind is measured at 2 m. Measurements are made at 10 s intervals, data are averaged and recorded every 15 min in the data logger.

Daily or Monthly water level at a gauging station

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.
