Project summary

Edit project overview to modify the project summary.

This reach of the Anzur River at Aldea de Nacimiento (Rute municipality, Cordoba, Spain) had flooding and incision problems. The riparian vegetation was altered by the presence of exotic species (Arundo donax) or the absence of coverage by native species. Other problem related to the urbanization was the presence of debris and waste at the channel. The project aimed to reduce the floods by increasing the width of the channel and its hydraulic capacity. Along with this intervention, there were other actions, based on bioengineering techniques or materials that allow their environmental integration, with the objective of improve the environmental condition of the reach and the landscape.
