- Abstract
The confining barrier comprising the Salinas-El Espartal beach/dune system forms part of the mouth complex of the Avilés estuary on the central coast of Asturias (NW Spain). In this study the evolution of the beach and its dune field, as well as the estuary, is established based on appraisal of both natural and anthropogenic processes. In particular, dredging in the estuary mouth has had a strong negative impact on the system, including the recession of the dune front by between 20 and 30 m, and degradation of the seafront, first built at the edge of the beach dunes in 1965 and rebuilt in 1994. By contrast, the dumping of dredged material at a nearby beach, Xagó, has caused a remarkable dune progradation of 45 m on average, creating aeolian tabular sheets. The future dredging management of the mouth of the Avilés estuary should be directly related to the evolution of the El Espartal and Xagó dune fields.
