The Battle of the Leakage Detection and Isolation Methods (BattLeDIM) 2020 aims at objectively comparing the performance of methods for the detection and localization of leakage events, relying on SCADA measurements of flow and pressure sensors installed within water distribution networks. Participants may use different types of tools and methods, including (but not limited to) engineering judgment, machine learning, statistical methods, signal processing, and model-based fault diagnosis approaches.
