The application uses the parameter granulometry deduced from borehole lithological records to create interactive 3D HTML models of essential stratigraphic elements. On the basis of the high density of boreholes and the subsequent geological knowledge gained during the last six decades, the Quaternary onshore Llobregat River Delta (LRD) in northeastern Spain was selected to show the application. The public granulometry dataset produced by the Water Authority of Catalonia from 433 boreholes in this strategic coastal groundwater body was clustered into the clay\u2013silt, coarse sand, and gravel classes. Three interactive 3D HTML models were created. The first shows the location of the boreholes granulometry. The second includes the main gravel and coarse sand sedimentary bodies (lithosomes) associated with the identified three stratigraphic intervals, called lower (&gt;50 m b.s.l.) in the distal LRD sector, middle (20\u201350 m b.s.l.) in the central LRD, and upper (&lt;20 m b.s.l.) spread over the entire LRD. The third deals with the basement (Pliocene and older rocks) top surface, which shows an overall steeped shape deepening toward the marine platform and local horsts, probably due to faulting. The modeled stratigraphic elements match well with the sedimentary structures reported in recent scientific publications. This proves the good performance of this incipient Python application for visualizing the 3D stratigraphic architecture, which is a crucial stage for groundwater management and governance.<\/jats:p>","DOI":"10.3390\/w14121882","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T06:31:59Z","timestamp":1655101919000},"page":"1882","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A Python Application for Visualizing the 3D Stratigraphic Architecture of the Onshore Llobregat River Delta in NE Spain"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6914-8052","authenticated-orcid":false,"given":"Manuel","family":"Bullejos","sequence":"first","affiliation":[{"name":"Departamento de \u00c1lgebra, University of Granada, 18010 Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7823-6756","authenticated-orcid":false,"given":"David","family":"Cabezas","sequence":"additional","affiliation":[{"name":"Departamento de An\u00e1lisis Matem\u00e1tico, University of Granada, 18010 Granada, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5797-9892","authenticated-orcid":false,"given":"Manuel","family":"Mart\u00edn-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Departamento de Ciencias de la Tierra y Medio Ambiente, University of Alicante, 03080 Alicante, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8165-8669","authenticated-orcid":false,"given":"Francisco Javier","family":"Alcal\u00e1","sequence":"additional","affiliation":[{"name":"Departamento de Desertificaci\u00f3n y Geo-Ecolog\u00eda, Estaci\u00f3n Experimental de Zonas \u00c1ridas (EEZA\u2013CSIC), 04120 Almeria, Spain"},{"name":"Instituto de Ciencias Qu\u00edmicas Aplicadas, Facultad de Ingenier\u00eda, Universidad Aut\u00f3noma de Chile, Santiago 7500138, Chile"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,11]]},"reference":[{"key":"ref_1","first-page":"436","article-title":"Seawater intrusion in the Llobregat Delta near Barcelona (Catalonia, Spain)","volume":"Volume 45","author":"Custodio","year":"1987","journal-title":"Groundwater Problems in the Coastal Areas, Studies and Reports in Hydrology"},{"key":"ref_2","unstructured":"(2022, April 18).
