  abstract = {{T}his paper assesses the sustainability of planned water uses in mesoscale river basins under multiple climate change scenarios, and contributes to determining the possible causes of unsustainability. {W}e propose an assessment grounded in real-world water management issues, with water management scenarios built in collaboration with local water agencies. {F}urthermore, we present an analysis through indicators that relate to management goals and present the implications of climate uncertainty for our results, furthering the significance of our study for water management. {A} modeling framework integrating hydro-climatic and human dynamics and accounting for interactions between resource and demand was applied in two basins of different scales and with contrasting water uses: the {H}erault (2500 km(2), {F}rance) and the {E}bro (85 000 km2, {S}pain) basins. {N}atural streamflow was evaluated using a conceptual hydrological model. {A} demand-driven reservoir management model was designed to account for streamflow regulations from the main dams. {H}uman water demand was estimated from time series of demographic, socioeconomic and climatic data. {E}nvironmental flows were accounted for by defining streamflow thresholds under which withdrawals were strictly limited. {F}inally indicators comparing water availability to demand at strategic resource and demand nodes were computed. {T}his framework was applied under different combinations of climatic and water use scenarios for the mid-21st to differentiate the impacts of climate- and human-induced changes on streamflow and water balance. {R}esults showed that objective monthly environmental flows would be guaranteed in current climate conditions in both basins, yet in several areas this could imply limiting human water uses more than once every 5 years. {T}he impact of the tested climate projections on both water availability and demand could question the water allocations and environmental requirements currently planned for the coming decades. {W}ater shortages for human use could become more frequent and intense, and the pressure on water resources and aquatic ecosystems could intensify. {T}he causes of unsustainability vary across sub-basins and scenarios, and in most areas results are highly dependent on the climate change scenario.},
