Description du jeu de données
RésuméLong term measurements (LOP) of the river discharge to documentate the surface water balance of 6 nested catchments (12 to 586 km2). The electrical conductivity of river water is an integrative measure that allows documentation of the origin of waters (rainfall, surface and sub-surface runoff, water table drainage). Associated to the chemical characterization of water (instrument CE.Wchem_Od), these data give insight into processes of runoff generation, allow to compute water balance components and constitute validation datasets for hydrological models.
Strategie d'observationAutomatic measurements (5-min to 1-hour) of water level and electrical conductivity. Calibration of the stage-discharge relationship is made using an Acoustic Doppler Current Profilometer (instrument CL.ADCP_O).
6 stations deployed over the Donga catchment. Running period 2002-2010 (discharge) and 2004-2010 (conductivity). Logistics and maintenance by IRD teams.

Information sur l'utilisation des données
Conditions d'utilisation des donnéesPermission is granted to use these data in research and publications when accompanied by the following statement: "The AMMA-CATCH regional observing system was set up thanks to an incentive funding of the French Ministry of Research that allowed pooling together various pre-existing small scale observing setups. The continuity and long term perenity of the measurements are made possible by an undisrupted IRD funding since 1990 and by a continuous CNRS-INSU funding since 2005."
