CASE OF STUDY: IMPROVEMENT OF THE ECOLOGICAL STATUS OF THE RIVER ÓRBIGO (LEÓN, SPAIN)


Removal of gravel embankments in land use areas compatible with floods

The EU Directive on the assessment and management of flood risks (2007/60/EC) presents a new approach to tackle flood risk management, based primarily on the prevention, protection, and preparedness, with the promotion of measures for river restoration, prediction of floods, civil protection or land management. This represents a shift over the traditional, structural approach, to the principle of avoiding unneccessary deterioration of river ecosystems, as set out in the Water Framework Directive.


Retreat and re-allocation of gravel embankments next to infrastructures

The project improvement of the ecological status of the river Órbigo responds to these premises. The actions therein have been aimed at the recovery of the river area and the functionality of the floodplain to increase the efficiency in the dissipation of floods, and to start the self-ecological recovery by connecting the river with related riparian areas.
