Leak detection and location in a real water distribution network using a model-based technique

[EN] This paper presents a practical application of a model-based approach for leak detection and location in a real water distribution network. The methodology is divided into three main steps: 1) identification of the DMA with the highest leakage volume; 2) hydraulic model update and 3) leak locat...
