Estudos de calibração de redes de abastecimento de água utilizando o acoplamento dos softwares R e EPANET

Abstract

In view of the indisputable demand for water resources, in terms of quality and quantity increasingly increasing in urban centers, water supply systems, especially such as water networks, play an important role in terms of urban infrastructure. Predicting the behavior of hydraulic structures using modeling and simulation is important for managers of different types, both public and private. Over the years, constant physical and operational changes occur in networks, such as changes in the physical roughness of pipelines, requiring dynamic adjustments as well as mathematical models to predict their hydraulic behavior in order to modify and improve their parameters. Inverse calibration of the water distribution network is the process of adjusting non-measurable parameters based on parameter measurements such as pressure and flow. There are methodologies for this source, however there is no knowledge of calibration research using the EPANET software coupled to the R, exploring the hydraulic evaluation resources of the first and a data analysis of the second. Thus, the objective of the present work was to evaluate the original potential of using these two tools for a calibration adjustment. To achieve this objective, the methodology was to apply this coupling in a theoretical network developed for the study. The results proved to be good, having a good fit between the reference values considered measured and those generated by the simulation. It is concluded that there is potential to use this tool for new studies and, in the future, for applications in real water supply networks.
