Abstract
In the context of insufficient data in a given area, it is recommended to use hydrological models at low settings. This avoids the risk associated with the parameters of the model uncertainty increases. In this study, we propose to calibrate the overall conceptual model TANK Ubangian in the watershed. It is classified in the category of watersheds little instrumented. Analysis of the performance of the TANK model and the surface runoff coefficient show good calibration results TANK model. On average, the value of the Nash-Sutcliffe criterion is estimated at 0.73.

Abstract: (french)
Dans le contexte de l’insuffisance de données dans une région donnée, il est recommandé d’exploiter des modèles hydrologiques à peu de paramètres. Cela permet d’éviter le risque associé à l’augmentation d’incertitude de paramètres du modèle. Dans cette étude, nous proposons d’étalonner le modèle conceptuel global TANK dans le bassin versant Oubanguien. Ce dernier est classé dans la catégorie des bassins versants peu instrumentés. L’analyse de la performance du modèle TANK et celle de coefficient de ruissellement de surface montrent de bons résultats d’étalonnage du modèle TANK. En moyenne, la valeur du critère de Nash-Sutcliffe est estimée à 0.73.
