Management of coastal dunes on the Catalan and on the Valencian shorelines (Spain)

Coastal areas constitute one of the most difficult domains to manage, due several human activities and natural processes concentrated in it. The case coastal dunes is special, since they are so fragile any intervention on them can cause alterations landforms dynamics. This work assesses level role management morphological status Catalan Valencian shorelines. To that end, ten beach-dune systems from shorelines have been studied guess how actions determine them. A set variables, comprising status, selected analyzed through a Hierarchical Clustering Principal Components (HCPC). Results show be gathered 2 main groups: those where sustainable measures were not applied present an advanced erosive state, ones good state conservation. conservation related restoring applying nature-based solutions, whereas degraded morphologies appear when artificial carried out.
