Detecção de vazamentos em redes de distribuição de água pela aplicação do Método Iterativo do Gradiente Hidráulico Alternativo (MIGHA) para calibrar vazões mediante modelagem computacional

Abstract

Detection of leaks in supply systems is of paramount importance to combat the waste of drinking water as well as to improve the efficiency of water distribution systems. In this work a routine was developed, based on the Alternative Hydraulic Gradient Method (MIGHA), to calibrate the flow of a network and later use the calibration results to detect possible leakage points. The results show that the method can identify the nodes and sections where the leaks may be located. Regarding the calculation of the location of the leaks in the sections, the results were satisfactory when the leak has no influence of other nearby leaks.
