Usually, it is used in emergency situations as a local and short-term solution or as a regional and long-term management strategy.&lt;\/p&gt;&lt;p&gt;From April 2017 to November 2019, sediment samples and beach profile data were collected seasonally, before and after a sand nourishment (100.000m&lt;sup&gt;3&lt;\/sup&gt;) that increased 30m of width in Belharucas beach (south Portugal, Algarve).&lt;\/p&gt;&lt;p&gt;The main objective of the work was to evaluate the nourishment impact in the beach ecosystem, aiming at contributing to seafloor integrity assessment, in the scope of Descriptor 6 of the Marine Strategy Framework Directive.&amp;#160;&lt;\/p&gt;&lt;p&gt;Methodology included grain size and macrobenthic fauna analyses in two profiles of the nourished area and another one further away, selected as a control area. Each profile was sampled at three intertidal zones: supralittoral (beach berm), mediolittoral (beach face) and infralittoral (low tide terrace).&amp;#160; Beach profile data were collected with the main objective of measuring the beach width and evaluate nourishment longevity.&lt;\/p&gt;&lt;p&gt;Results show that grain size variability, higher at beach face, is dominated by local energy beach conditions rather than to changes related to the nourishment.&lt;\/p&gt;&lt;p&gt;Morphological data shows that beach nourishment had a relatively low longevity as two years after the nourished beach present roughly the same width as priori to nourishment.&lt;\/p&gt;&lt;p&gt;While supralittoral samples were defaunated, medio and infralittoral ones exhibited extremely low diversity. Assemblages were dominated by small-size polychaetes, bivalves and isopods. No statistically significant differences were found in assemblage composition regarding pre- and post-sand nourishment, year seasons, tidal zones and control stations.&lt;\/p&gt;&lt;p&gt;In conclusion, Belharucas beach exhibited high resilience to the sand nourishment, preserving its morphodynamics and ecosystem conditions.&lt;\/p&gt;&lt;p&gt;&amp;#160;&lt;\/p&gt;&lt;p&gt;The authors would like to acknowledge the financial support FCT through project UIDB\/50019\/2020 &amp;#8211; IDL and through the strategic project UIDB\/MAR\/04292\/2019 - MARE and ECOEXA project (MAR-01.04.02-FEAMP-0016)&lt;\/p&gt;<\/jats:p>","DOI":"10.5194\/egusphere-egu21-15838","type":"posted-content","created":{"date-parts":[[2021,3,4]],"date-time":"2021-03-04T13:44:21Z","timestamp":1614865461000},"source":"Crossref","is-referenced-by-count":0,"title":["Morphosedimentary and ecosystem evolution at Belharucas beach after a sand nourishment (Algarve, south Portugal)"],"prefix":"10.5194","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3496-3270","authenticated-orcid":false,"given":"Teresa","family":"Drago","sequence":"first","affiliation":[]},{"given":"Sebasti\u00e3o","family":"Teixeira","sequence":"additional","affiliation":[]},{"given":"Marcos","family":"Rosa","sequence":"additional","affiliation":[]},{"given":"Miriam","family":"Tuaty-Guerra","sequence":"additional","affiliation":[]},{"given":"Maria Jos\u00e9","family":"Gaud\u00eancio","sequence":"additional","affiliation":[]},{"given":"Jorge","family":"Lobo-Arteaga","sequence":"additional","affiliation":[]},{"given":"Arthur","family":"Veronez","sequence":"additional","affiliation":[]},{"given":"Rui","family":"Taborda","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7831-1069","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Cascalho","sequence":"additional","affiliation":[]}],"member":"3145","container-title":[],"original-title":[],"deposited":{"date-parts":[[2021,3,4]],"date-time":"2021-03-04T13:47:56Z","timestamp":1614865676000},"score":1,"resource":{"primary":{"URL":"https:\/\/meetingorganizer.copernicus.org\/EGU21\/EGU21-15838.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3,4]]},"references-count":0,"URL":"https:\/\/doi.org\/10.5194\/egusphere-egu21-15838","relation":{},"subject":[],"published":{"date-parts":[[2021,3,4]]},"subtype":"other"}}
