| description |
Most of the beach-dune systems in the western Mediterranean today show an important state of fragmentation with obvious signs of erosion, largely because of blowouts on the dune front. Blowouts were studied in the dune front of the Cala Agulla beach-dune system (Mallorca, Spain) in order to better understand and quantify the backward dune movement over the last decades. A spatiotemporal analysis taking into account the boundary drawn by the vegetation along the first line of dunes was carried out. The analysis was performed using GIS software ArcView, applying DSAS extension 2.0 (Digital Shoreline Analysis System). Fourteen blowouts located along a front about 600 m long were studied. For each blowout, some ecological and morphometric variables were analyzed in order to establish the relationship between the different types of blowouts. To this end, it was applied an index Rt-v to link each morphology with the patterns shown by the existing vegetation, both herbaceous and woody. Applying the iTx index represents the link between each typology and its inner topography. The results show integral recoil of the dune front over the last decades - the average recoil ranges from 10-20 m, although in some places exceed 20 m -. However, from 2008 to 2010 some advances were recorded, except at the sites that coincided with the main entrances to the beach, which suggests a direct relationship between maximum erosion and the places with highest attendance. Blowouts were divided into 5 categories, trough blowouts being the most prevalent (50% of samples). Each type showed distinct morphometric features and had a different relationship with the vegetal species. |

S’estudien els blowouts existents al front de dunes del sistema de Cala Agulla (Mallorca, Espanya) amb l’objectiu de conèixer i quantificar el retrocés del sistema al llarg de les darreres dècades. Per això s’ha realitzat una anàlisi espacio-temporal prenent com a línia de referència la marcada per la presència de vegetació herbàcia. L’anàlisi s’ha dut a terme a partir de la utilització del sistema d’informació geogràfica ArcView, i amb l’aplicació de l’eina DSAS (Digital Shoreline Analysis System). Un total de 14 blowouts localitzats al llarg d’un front dunar de 600 m han estat estudiats. Per a cada un dels blowouts algunes variables geomorfològiques i ecològiques han estat analitzades en tant a poder establir una relació entre els distints tipus de blowouts. Amb aquest fi, s’aplica l’índex Rt-v per tal de relacionar cada morfologia amb els patrons mostrats per la vegetació existent, tant herbàcia com arbustiva. D’altra banda, l’aplicació de l’índex iTx representa la relació existent entre cada tipologia i els seus perfils topogràfics interns. Els resultats obtinguts mostren un retrocés integral del front de dunes al llarg de les darreres dècades – el retrocés mitjà oscil·la entre els 10-20 m, tot i que en alguns llocs aquest excedeix els 20 m –. No obstant, de 2008 a 2010 es perceben alguns punts d’avançament, sempre excepte els indrets que coincideixen amb les entrades principals a la platja, la qual cosa suggereix una relació directe entre els màxims d’erosió i els llocs amb major influència d’usuaris. Els blowouts han estat dividits en 5 categories, sent els trough blowouts els que més importància tenen (50% de la mostra). Cada una de les tipologies mostra característiques morfomètriques diferents, i distinta relació amb les espècies vegetals inventariades.Societat d'Història Natural de les Balears2014info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://ibdigital.uib.es/greenstone/sites/oai-site/collect/bolletiHistoriaNatural/index/assoc/Bolleti_/2014v057/p079-1.dir/Bolleti_2014v057p079.pdfhttp://ibdigital.uib.es/greenstone/library/collection/bolletiHistoriaNatural/document/Bolleti_2014v057p079reponame:Biblioteca Digital de les Illes Balearsinstname:Universidad de las Islas BalearesInglésBolletí de la Societat d'Història Natural de les Balears 2014, n. 57, pp. 79-103All rights reservedinfo:eu-repo/semantics/openAccessbolletiHistoriaNatural:Bolleti_2014v057p0792026-05-28T12:40:11Z |
