The Catalan Water Agency (ACA) has announced the expansion of the final 500 meters of the Tordera riverbed to reduce flood risk in the delta, a decision made after years of analysis following the Gloria storm.

This intervention, presented at the “La Tordera Delta Inundable” congress held in Malgrat de Mar, will involve shifting the river's right bank towards a secondary channel. The main objective is to increase drainage capacity during flood events, thereby improving the protection of nearby urban areas.
However, the measure will have a direct impact on the land located between the new river boundaries. The agricultural fields of Pla de Grau, in Malgrat de Mar, will be the most affected, as they will become more vulnerable to flooding during storms. The agricultural sector has expressed concern about the continuity of their activities, although potential compensation has been discussed.
A campsite located at the river mouth, in a particularly exposed area, will also be affected and is expected to be relocated. Details regarding the procedure and conditions of this relocation have not yet been defined.
From an environmental perspective, the project aligns with strategies that promote the recovery of space for the river and the fostering of the delta's natural dynamics. Experts suggest that this transformation can contribute to improving biodiversity and strengthening the ecological value of the environment.
The project is currently being finalized and will include a dialogue process with affected sectors to establish the transition to the new territorial management model.
