  25. 25. CONCLUSIONS <ul><li>ASDECO is an applied R&D project that will be accomplished with the actual monitoring and supervision needs of brine discharges. The tools and protocols defined within the project will be established as monitoring standards by the Desalination Plants Promoting Administration & the Environmental Authorities. </li></ul><ul><li>The project is close to achieving the complete development of an entire system that allows the implementation of Adaptive Management in brine discharges from desalination plants into the sea. </li></ul><ul><li>The project has made a proposal for data systematization. Associating a metadata to the measured time series has been a priority to conserve data traceability and quality assurance . </li></ul><ul><li>Therefore the application of neural fuzzy types such as ANFIS are a right tool for the follow-up and for the control of brine discharge into the sea. </li></ul><ul><li>A series of preliminary tests have shown that the discharged salt load and the maximum wave height are the variables with most influence on brine dispersal . </li></ul><ul><li>The integration of this real-time acquisition system with a Brine Dispersal Forecast Tool represents a technical advance in creating a complete Decision Support Tool . </li></ul>
