Résumé : Large river basins exhibit many local-scale management concerns for which a catchment-based approach is required. This study addresses the need for hydrological and water resources management information at the scale of decision making, the catchment. A hydrology and water resources planning modelling approach is applied to a transboundary river, the Inkisi River in Congo basin, based on six catchments partitioned using the catchment classification framework for the Congo basin. The model, developed for the reference period from 98 to 0, generates information on water availability and assesses future scenarios of climate change and water demand through 00. It is calibrated using 0 years of streamflow data and shows good performance based on objective functions of hydrological model evaluation. Assessment of climate change impacts under emissions scenarios RCP . and RCP 8. indicates a decreasing trend in water availability, highlighting the importance of adaptive water resources management strategies to address future challenges.
