This methodology is applied to a case study corresponding to the basin of the Longav\u00ed River, located in south-central Chile. Potential and estimated demands, aggregated at different spatio-temporal scales, are compared to the streamflow of the Longav\u00ed River, as well as extractions from the groundwater system. The results obtained allow us to conclude that the availability of spatio-temporal information on the water availability and demand pairing allows us to close the water gap\u2014i.e., the difference between supply and demand\u2014allowing for better management of water resources in a watershed.<\/jats:p>","DOI":"10.3390\/rs13112022","type":"journal-article","created":{"date-parts":[[2021,5,21]],"date-time":"2021-05-21T02:13:46Z","timestamp":1621563226000},"page":"2022","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Ex Post Analysis of Water Supply Demand in an Agricultural Basin by Multi-Source Data Integration"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5634-9162","authenticated-orcid":false,"given":"Mario","family":"Lillo-Saavedra","sequence":"first","affiliation":[{"name":"Facultad de Ingenier\u00eda Agr\u00edcola, Universidad de Concepci\u00f3n, Chill\u00e1n 3812120, Chile"}]},{"given":"Viviana","family":"Gavil\u00e1n","sequence":"additional","affiliation":[{"name":"Facultad de Ingenier\u00eda Agr\u00edcola, Universidad de Concepci\u00f3n, Chill\u00e1n 3812120, Chile"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6848-481X","authenticated-orcid":false,"given":"Angel","family":"Garc\u00eda-Pedrero","sequence":"additional","affiliation":[{"name":"Department of Computer Architecture and Technology, Universidad Polit\u00e9cnica de Madrid, 28660 Boadilla del Monte, Spain"},{"name":"Center for Biomedical Technology, Campus de Montegancedo, Universidad Polit\u00e9cnica de Madrid, 28233 Pozuelo de Alarc\u00f3n, Spain"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0804-9293","authenticated-orcid":false,"given":"Consuelo","family":"Gonzalo-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Department of Computer Architecture and Technology, Universidad Polit\u00e9cnica de Madrid, 28660 Boadilla del Monte, Spain"},{"name":"Center for Biomedical Technology, Campus de Montegancedo, Universidad Polit\u00e9cnica de Madrid, 28233 Pozuelo de Alarc\u00f3n, Spain"}]},{"given":"Felipe","family":"de la Hoz","sequence":"additional","affiliation":[{"name":"Centro del Agua para la Agricultura, Universidad de Concepci\u00f3n, San Fernando 3070000, Chile"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7863-4407","authenticated-orcid":false,"given":"Marcelo","family":"Somos-Valenzuela","sequence":"additional","affiliation":[{"name":"Department of Forest Sciences, Faculty of Agriculture and Forest Sciences, Universidad de La Frontera, Av.
