    Key features of the case study

    Site description

    The river segment under study is located at the region of Las Loras. Its lithology consists of alluvial material (fluvial origin) at the river channel,and marl and limestone mixed with sandy and clay materials in the rest of the basin.
    The flow regime is determined by the presence of the Aguilar dam. The partial or total elimination of the shore and riparian vegetation due to the agricultural land use has caused morphological changes in some channel reaches.
    In terms of its biota, the natural vegetation has disappeared in many places, being replaced by agricultural and forestry crops(poplar).
    the riparian vegetation is composed of willow shrubs, mainly Salix triandra, Salix elaeagnos, Salix purpurea, Salix, and Salix cantabrica salvifolia.

    Alteration of the water quality. Excess of turbidity due to the input of sediments from the Aguilar de Campoo dam.
    The presence of dikes hinder the migration of fish.
