Project summary

Edit project overview to modify the project summary.


Due to colonization and agricultural development, the river has been modified from its layout in plan and construction of longitudinal dykes. As a result of the loss of space, floods are quite common but not extraordinary floods. Riparian vegetation has disappeared. The river is restricted laterally and lost lateral connectivity, flood plain disappearing. The main objectives of the project are: improvement of the composition and structure of vegetation; improvement of longitudinal continuity of the river system; recovery of river morphology; and rehabilitation of degraded sections (urban). Removal of 7800m3 of sediments. This project counts with the support of national institutions. The financing comes from the Ministry of Environment. The total budget for carry out the rehabilitation is 4.382.861,36€.
