CEAB-CSIC is developing NEREIDA, a project that creates and uses digital twins (virtual replicas of rivers, reservoirs and coastal areas) to anticipate changes in water quantity and quality and support water resources planning and management, currently in the Ter and Tordera river basins. The project is funded by the Catalan Water Agency (ACA), which contributes through project oversight, data provision and technical guidance. Marking the project’s first year of implementation, the team has made the first operational tools for streamflow forecasting and saltwater intrusion prediction publicly available, together with the datasets they generate.<\/strong><\/h4>\n

Water management in Catalonia faces growing challenges: more frequent and intense droughts, extreme temperature events, pollution and the loss of aquatic biodiversity. In this context, the Blanes Centre for Advanced Studies of the Spanish National Research Council (CEAB-CSIC), with the support and oversight of the Catalan Water Agency, launched the NEREIDA project in July 2025 to place advanced scientific forecasting at the service of water management in Catalonia.<\/p>\n

NEREIDA<\/strong> <\/a>develops digital twins (virtual replicas of aquatic ecosystems) for the Ter and Tordera river basins, integrating hydrological, climate and water-quality models. Through the use of predictive modelling, high-performance computing and remote sensing, the project aims to provide reliable forecasts on seasonal timescales (up to seven months ahead) and long-term timescales (between one and ten years), strengthening the capacity to anticipate the impacts of climate change on water resources.<\/p>\n

The project’s main innovation lies in its focus on forecasting timescales that have received relatively little attention in the water sector, despite being among the most useful for management purposes because they enable medium and long-term planning. This information is highly relevant for water management and will provide a practical tool that can subsequently be used by the Catalan Water Agency and other organisations involved in water-resource management.<\/p>\n

First results now openly available<\/h4>\n

Although still in the first year of this three-year project, the team has already made the first preliminary operational tools publicly available. Through the project page on the CEAB website (https:\/\/www.ceab.csic.es\/projectes-recerca\/nereida\/<\/a>), users can access:<\/p>\n
