The Campo de Cartagena area of southeast Spain is a semi-arid region where irrigation return flow accounts for a substantial portion of recharge. In this study we estimated irrigation return flow using a root zone modelling approach in which irrigation, evapotranspiration, and soil moisture dynamics for specific crops and irrigation regimes were simulated with the HYDRUS-1D software package. The model was calibrated using field data collected in an experimental plot. Good agreement was achieved between the HYDRUS-1D simulations and field measurements made under melon and lettuce crops. The simulations indicated that water use by the crops was below potential levels despite regular irrigation. The fraction of applied water (irrigation plus precipitation) going to recharge ranged from 22% for a summer melon crop to 68% for a fall lettuce crop. In total, we estimate that irrigation of annual fruits and vegetables produces 26 hm3 y1 of groundwater recharge to the top unconfined aquifer. This estimate does not include important irrigated perennial crops in the region, such as artichoke and citrus. Overall, the results suggest a greater amount of irrigation return flow in the Campo de Cartagena region than was previously estimated."@es ; dct:identifier "43a60faa-d694-5da4-80da-694e4d32cf5f" ; dct:issued "2024-11-05T00:00:00+00:00"^^xsd:dateTime ; dct:language ; dct:license ; dct:modified "2026-06-25T00:00:00+00:00"^^xsd:dateTime ; dct:publisher ; dct:spatial ; dct:title "A root zone modelling approach to estimating groundwater recharge from irrigated areas"@es ; dct:type ; adms:identifier [ a adms:Identifier ; skos:notation "DOI: 10.1016/j.jhydrol.2009.01.002" ] ; adms:status ; dcat:contactPoint ; dcat:distribution ; dcat:keyword "agricultura"@es ; dcat:landingPage ; dcat:theme , . a foaf:Agent ; dct:identifier "E05068001" ; dct:type ; foaf:homepage ; foaf:mbox "bzn-datos@miteco.es" ; foaf:name "Inventario Español del Patrimonio Natural y de la Biodiversidad"@es . a dct:Location ; skos:prefLabel "Región de Murcia" ; dcat:bbox "POLYGON ((-2.3400 37.3800, -0.6900 37.3800, -0.6900 38.7600, -2.3400 38.7600, -2.3400 37.3800))"^^gsp:wktLiteral ; dcat:centroid "POINT (-1.5150 38.0700)"^^gsp:wktLiteral ; locn:geometry "POLYGON ((-2.3400 37.3800, -0.6900 37.3800, -0.6900 38.7600, -2.3400 38.7600, -2.3400 37.3800))"^^gsp:wktLiteral . a dct:LinguisticSystem . a dct:LinguisticSystem . a foaf:Document . a dcat:Distribution ; dcatap:applicableLegislation ; dcatap:availability ; dct:accessRights ; dct:format ; dct:issued "2009-01-21T00:00:00+00:00"^^xsd:dateTime ; dct:language ; dct:license ; dct:modified "2026-06-25T00:00:00+00:00"^^xsd:dateTime ; dct:title "Distribución HTML"@es ; cnt:characterEncoding "UTF-8" ; dcat:accessURL ; dcat:mediaType . a vcard:Kind ; vcard:fn "Organismo publicador del Catálogo"@es ; vcard:hasEmail ; vcard:hasURL ; vcard:role . a dct:Standard . a eli:LegalResource . dct:type .
