"The need for providing high quality water to citizens and to reduce damages produce by floods and droughts has motivated research and development of many software-based decision support systems (DSSs). However, despite the notable technical advances DSSs, most of the water infrastructures in Europe are still managed by expert operators based on traditional best practices but with little support from these new smart tools. The objective of SAID project is to involve the final users and the SMEs in order improve the production and deployment of more smart water management systems in Europe.The project will focus in the deployment and evaluation of a complex demonstrator, composed by several heterogeneous and innovative DSSs in the same river basin. This demonstrator, in the south of Spain, represents many similar basins in Europe, and will be based on cutting-edge DSS technologies in four areas: flood control (including the optimization of dam management), quality of water, energy production and energy consumption. The feedback from the final users will drive the improvement of the DSSs and the development and validation of a software platform that facilitate the integration of existing and future DSSs.SAID project will be carry out by water management authorities, companies operating water infrastructures, SMEs that produce DSS and research centers with proved knowledge in techniques and technologies for real-time data monitoring, environmental modeling, simulation and optimization of the water related elements.SAID will contribute to the initial action 1 (Smart water management systems) identified in the priority 4.7 Decision support systems and monitoring in the Strategic Implementation Plan of the EIP on Water."
