More model informationThe Douro river is incised 250 m in the peneplain. The Pisón stream negotiates the abrupt change of slope and configures a deep, narrow valley, where small waterfalls, rapids and potholes are frequent. Some residual reliefs stand out as inselbergs (El Castillo) and nubbins (El Modorro) on the surface of Plio-Pleistocene erosion.
