Simulação mensal do sistema hídrico Curema-Mãe D’Água: uma análise operacional.

Abstract

The Curema-Mãe d'Água water system, located in the state of Paraíba, is essential for water supply in a region frequently affected by droughts. The aim of this study was to assess whether the simplification of treating the interconnected reservoirs as a single equivalent reservoir results in significant losses in the operational analysis of the system. To this end, hydrometeorological and technical data on the reservoirs of the Curema-Mãe D'Água system were collected from the National Water and Basic Sanitation Agency, and mathematical models were applied in Microsoft Excel to model the dynamics of the reservoirs. The calibrated height-area-volume curves were fundamental to understanding the system's behavior. The simulation of the equivalent reservoir model showed satisfactory results and a good correlation with the operation of the interconnected reservoirs, although it required special attention to the spills, which showed the greatest discrepancy. It is concluded that considering the reservoir as equivalent allows for more agile analysis and facilitates understanding of the functioning of the water system in question.
