Vallina

The fluvial environment of the rivers in the eastern region of Asturias is subject to continuous and progressive deterioration as a result of the human settlements and activities that have been established on their banks. The situation of deterioration is especially relevant in the Vallina River, a 3-kilometre fluvial course located in a karst area that flows from its spring “Fuente Vallina” in the town of Porrúa to its mouth in Póo. It is at this point where it connects with the Cultural Route of the Council of Europe, Santiago de Compostela pilgrim route. The Vallina River is typified as a pluvial type associated with intense rainfall. Having an irregular course, it presents dry periods and periods of flooding, which entails greater impact on the ecosystem when the river carries debris or waste.
