| Description du jeu de données | |||
| Résumé | Long 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'observation | Automatic 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 données | Permission 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." | ||
