SUMMARY:

This research aims to investigate the uncertainties associated with the construction of Risk Aversion Curves (CAR) in the operation of reservoirs within the framework of negotiated water allocation processes. The study emphasizes the importance of negotiated allocation as a tool for decentralized water resource management, promoting the participation of users in decision-making bodies for defining the operating rules of reservoirs. To investigate these uncertainties, variations in input data were used to assess the impacts of variability and hydrological and physical uncertainties on the CAR. The input data for the reservoir operation model included inflow discharge, precipitation, evaporation, water demands, and reservoir volume. The Cruzeta Reservoir, located in the Seridó River Basin, was selected as the study object. The results show that the inflow discharge and demand input values directly impact the determination of the curves. Another interesting finding is the behavior of the reservoir in response to the volume of precipitated water, even though this has no significant influence on the curve determination. The study highlights a relatively unexplored research area within the universe of negotiated allocation, specifically the improvement of the CAR model, which is often seen as a secondary aspect in processes focused on resolving water conflicts.
