| Sumario: | [EN] Hydraulic models of water distribution systems are widely used by water utilities and consultants to assist in planning, design, evaluation of the operation, analysis of energy management and water quality analysis; and lately have gained importance among the regulatory community water services for decision-making regarding consumer safety and capital investment, becoming an indispensable tool for supply management. Thus, the more accurate the hydraulic model, it is more reliable as a support tool for decision making, and therefore this calibration is a fundamental requirement at the time of development. This investigation work proposes a methodology for preliminary calibration of hydraulic models. Based on a number of assumptions and theoretical formulations advanced calibration techniques. The proposed methodology is based on the modeling of the pressure-dependent demands, spatially distributed according to the length of the pipes and the level of estimated leakage for network sectors defined in the distribution system. It consists of four basic processes that seek to gauge the overall emitter leakage, determine the coefficients of the consumption pattern for the base demand, adjust the valve loss coefficients, and calibrate the leakage emitters assigned to the nodes of the hydraulic model. To validate the proposed methodology, it has been applied in three case studies; sectors of the water distribution system with different volumetric flows belonging to the water supply system of the city of Guayaquil (Ecuador). |
