Review of Water Network Analysis and Validation of SCALER Hydraulic Simulator

The article intends to present the validation stage of a software to model and simulate hydraulic networks for water distribution, the SCALER, through its application to a real system, with many branches, with a model previously developed and verified using the EPANET software. SCALER was developed in 2020 and 2021 and, until then, had only been applied to networks with a relatively small number of branches. After discussing topics related to hydraulic modeling of distribution networks, techniques and applications, a brief review of the fundamentals of SCALER is carried out, passing on to its application to the case at hand, which is the Vila Joaniza community, in the municipality of Rio de Janeiro. Data from image, scheme and table are used to assist in the description of the local situation and respective distribution network, with the objective of assessing whether the nodal pressures obtained by SCALER are sufficiently similar to those obtained by EPANET, in order to ensure the proper functioning of the software. After this step, and the calculations have been made by the program, an operation screen, the generated graph of the local situation and a table with the comparison of absolute and percentage deviations between the nodal pressures resulting from the SCALER and those obtained with the EPANET are inserted, confirming that the deviation values are quite small, which validates SCALER as a software also applicable to networks with many branches.
