    • Chlorine concentration modelling and supervision in water distribution systems 

      Pérez Magrané, Ramon; Martínez Torrents, Albert; Martínez del Álamo, Manuel; Grau Torrent, Sergi; Vinardell Magre, Laura; Tomàs Puig, Ricard; Martínez Lladó, Xavier; Jubany Güell, Irene (Multidisciplinary Digital Publishing Institute (MDPI), 2022-07-26)
      Article
      Accés obert
      The quality of the drinking water distributed through the networks has become the main concern of most operators. This work focuses on one of the most important variables of the drinking water distribution networks (WDN) ...

    • Data setup for water distribution system supervision 

      Pérez Magrané, Ramon; Grau Torrent, Sergi; Jimenez, Victor; Martínez, Xavier; Tomas, Ricard (2017)
      Text en actes de congrés
      Accés obert
      The availability of on-line data coming from the water distribution systems (WDS) allows the monitoring of such critical infrastructures. Nevertheless the huge amount of data that come to the control centre implies an ...

    • Flow Data Based DMA Characterisation 

      Grau Torrent, Sergi; Pérez Magrané, Ramon (2019)
      Comunicació de congrés
      Accés restringit per política de l'editorial
      Data in water companies have been collected since sensors (level, pressure, flow, Temperature, chlorine concentration, etc.) have been gradually introduced. Supervision and control of processes were the first drivers of ...

    • Leak detection in a DMA, a real application of flow modelling 

      Jiménez, Víctor; Grau Torrent, Sergi; Pérez Magrané, Ramon (2017)
      Text en actes de congrés
      Accés obert
      This paper presents a versatile methodology to calculate parameters that characterise the demand of a DMA. This parameters are used for the leak modelling so that a predictive model is built and trained with historical ...

    • Long and short term demand forecast, a real application 

      Grau Torrent, Sergi; Luis, Anna; Saludes Closa, Jordi; Pérez Magrané, Ramon (2019)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Two of the main purposes of a water supply company are the operation of the network and its planning. One of the critical elements for the planning and the operation is the demand forecast. There are multiple methods for ...

    • Model calibration and leakage assessment applied to a real Water Distribution Network 

      Roma, Josep; Pérez Magrané, Ramon; Sanz Estapé, Gerard; Grau Torrent, Sergi (Elsevier, 2015)
      Text en actes de congrés
      Accés obert
      The use of water distribution network models depends highly on the confidence that the operators have on them. Models generated automatically from the Geographical Information System using the hydraulic equations integrated ...

    • Modelling daily water consumption through potential curves. Disaggregating apparent and real losses 

      Grau Torrent, Sergi; Pérez Magrané, Ramon (Taylor & Francis, 2020-05-18)
      Article
      Accés obert
      This paper presents a model, based on potential curves, that describes the behaviour of the inverse of the daily cumulated frequency of the flows provided to a District Metered Area (DMA). The model has two terms, the first ...
