The goal of this work is to study the degree of reliability, resilience and vulnerability (RRV) of the water resource system Cañete River Basin, using the WEAP model. The System considers the main sources of surface water and the volume of water use rights, it does not include the volume of exploitation of underground water and the demands that is supplied from it. Nine estimators of RRV proposed in the literature were examined (two of reliability, 3 of resilience and four of vulnerability) in order to select the most appropriate combination in terms of sensibility, monotony and degree of overlap. The selected estimators were aggregated into Sustainability Indices by groups of water users to make the comparison between sectors easier (agricultural, energetic, population, ecological) and to evaluate the general status of the system. The results show that the most appropriate combination of estimators for the System is: time-based reliability (Relt ); resilience based on maximum values of failure duration (Resmax) and vulnerability based on mean values of maximum deficits (Vulhmax). The analysis of RRV shows that the operations of the Paucarcocha reservoir has improved the system to meet the volume of water rights not only for the energy sector, but also for the agricultural sector, especially in the lower basin during the dry season. However, if the demand of this sector increases by 10 percent or even less, there would be a rapid degradation in the degree of RRV; in the same way, if the ecological requirement flow is determined and set above 4 m3 s -1 in the valley, would make it difficult for the system to meet the demands. The result of this study suggests that the water resource management should be based on multiple indicators and indices that help to identify the capabilities and characteristics of the system to guarantee the sustainability of the water use rights.
