ANÁLISE COMPARATIVA DE MÉTODOS DE DISTRIBUIÇÃO DE DEMANDAS EM SISTEMAS DE ABASTECIMENTO DE ÁGUA

Abstract

This study investigates different approaches to demand distribution in hydraulic networks, considering scenarios with limited commercial and operational data. Four methods were analyzed: distribution by georeferenced registrations, distribution by influence area, uniform distribution among nodes, and proportional distribution by roof areas. The accuracy of these methodologies was assessed using fundamental hydraulic parameters such as Unit Head Loss, average velocity, and flow rate. The results indicate that the Method of Distribution by Roof Areas (MDAT) offers greater precision in densely occupied sectors, with variations of only 1% compared to the baseline method. However, its application in regions with low building density revealed limitations, registering variations of up to 20%. The Method of Uniform Distribution by Area (MDUA) proved to be more efficient for areas in the early stages of occupation, eliminating the need for interpolation with demographic density and facilitating implementation. The study highlights the importance of commercial and operational data availability to ensure greater accuracy in hydraulic modeling and contribute to the effective planning and management of water supply systems
