Low reach of River Cinca
Low reach of River Cinca
Key features of the case study
The objective of the project is to restore the stream morphology and floodplain conditions of the river Cinca in the lower reach, between Velilla de Cinca and Fraga. There are a major actuation that consist of remove a levee that only protect crops.
Site description
The river Cinca is one of the largest rivers in the Ebro Basin that drains part of the North of Aragon, in Spain. The river has a lot of impacts in both riverbanks: crops, urban areas, reforested areas, levees, communication infrastructures...
There is a huge presence of sediments inside the stream that usually formed bars, more or less colonized by natural vegetation. The flow regime is regulated by upstream dams like "Mediano" o "El Grado" (436hm3 and 399hm3).
The presence of crops and cutivated areas has contributed to build defenses and to profit the fertile soils to plant black poplars.
