The objective of this article is to simulate and extend hydrological data, using the GR2M rainfall-runoff model. A sensitivity analysis of the model to rainfall and water holding capacity input data was performed. This analysis was performed after calculating catchment rainfall, mean potential evapotranspiration, and maximum, minimum and mean water holding capacity. The best combination of input data was chosen by catchment based on the Nash-Sutcliffe criterion. Then cross calibration-validation tests were performed, using the selected input data to choose model parameter sets. specialized upper Senegal River basin rainfall-runoff modelling water resources GR2M streamflow SENEGAL BASSIN 062 020 32 1 89-101 2016 0790-0627 https://www.documentation.ird.fr/hor/fdi:010066011 10.1080/07900627.2015.1026435 0790-0627 [F B010066011] https://www.documentation.ird.fr/hor/fdi:010066011 https://www.documentation.ird.fr/intranet/publi/depot/2021-04-19/010066011.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2016-02-02 2021-04-20 fdi:010066011 fre
