    Key features of the case study

    This reach of the Anzur river at Aldea de Nacimiento (Rute municipality)experimented 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 problems 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.

    Site description

    Measures selection

    The works combined techniques of bioengineering, hard-engineering, and plantations:

    • Silvicultural treatments. Selective clearing of brambles (Rubus sp.) and reed (Arundo donax).
    • Improvement of channel morphology (regrading streambanks to a stable slope, widening the channel).
    • Bank stabilization with coconut fiber - polypropylene geogrid and cylindrical rows of gabions buried 1 m from the base. Seeds of native species are placed at the grid for facilitate bank revegetation.
    • Protection and correction of incision problems with cylindrical gabions.
    • Revegetation of the riparian zone with plantations of poplar (Populus alba), elm (Ulmus minor), fig (Ficus carica), oleander (Nerium oleander) and tamarisk (Tamarix sp.).
    • Prevent and reduce bank erosion with live stakes of oleander and tamarisk.
