RealQual aimed at developing the foundations of a quality-controlled network for real-time high-resolution monitoring and prediction of the water quality in estuaries and coastal areas, in particular to anticipate potential eutrophication events.


  • To develop a pilot demonstration of the real-time water quality network in the Tagus estuary (Portugal)
  • To improve an operational platform for automated management of the monitoring and predicting water quality network
  • To develop an effective predictive system for water quality, exploring strategies that use of models of different complexity and computational cost
  • To transfer OHSU's knowledge on sophisticated observation networks for water quality and to integrate it with LNEC’s strategies for data quality

Next challenges

  • Integrate the water quality monitoring and forecast platform in the INCD
  • Apply the system to other estuaries
