Geração automática de redes de distribuição de água a partir da definição das linhas centrais das ruas

Abstract

This work proposes an algorithm for the automatic generation of the layout of distribution networks on EPANET using only the street layout contained in a CAD file. For For this, a CAD file was read, whose extension is DXF, and all the entities that make up the boundaries of the streets, with the conversion of the arches into sets of lines of short length that form an arc-like geometry original. In this way, the entire layout of the streets will be composed only of lines, which will be worked mathematically through parametric equations of straight lines. For that, initially, the central lines of the streets are defined in a first version, which are extended generating intersection points that will be used to determine the nodes of the network. Soon after, the lines that intersect the layout of the streets are trimmed, ensuring that all centerlines are fully within street boundaries. Then, the generated pipes that connect the nodes which connectivity has been proven and, finally, the junctions of the pipes are identified to create the EPANET input file. Three layouts of streets with different particularities were used to prove the effectiveness of the model, one being hypothetical and two real. For all tested street layouts, the proposed algorithm achieved satisfactory results, automatically generating the entire layout of the networks in a EPANET input file. In addition, the results were compared with those obtained by the model by Costa and Rodrigues (2021), which is a pioneering work on the subject. OK highlight that the present model brings as innovation the good performance both for streets orthogonal and for inclined and arched streets.
