This study elucidates salinity sources and quantifies inter-aquifer mixing dynamics using an integrated approach combining self-organizing map (SOM) analysis, NETPATH inverse modeling, multiple isotopic tracers (δ 1 ⁸O, δ 2 H, ⁸⁷Sr/⁸⁶Sr, 13 C, 14 C), and 3D numerical modeling with reverse particle tracking. Analysis of 153 water samples revealed three distinct hydrochemical groups: High salinity TCA waters influenced by evaporation and recharge from salt lakes, intermediate salinity mixing zones, and low-salinity NSSA paleowaters aged 4,300–14,200 years. Salt lake contributions to TCA groundwater salinity range from 0.6–18%, while fault-controlled NSSA discharge contributes 52–90% to TCA recharge. Predictive modeling indicates the non-renewable groundwaters in the NSSA will experience 30–40 m of drawdown by 2100 under current groundwater abstraction rates, exacerbating TCA salinization. These findings provide a framework for sustainable groundwater management in complex arid aquifer systems and highlight the urgent need for protection of fault-controlled recharge zones. true 2026 true true true false true false NONE 2026-07-31 false 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 15 15 Q1 A false false false false 2026-05-25T11:04:20.975+0000 HUN-REN Atommagkutató Intézet; Víz- és Környezetgazdálkodási Intézet (ME / MFK) 6 18 2 7 0 true 10096252 Language 10002 /api/language/10002 Angol Angol English true 2 true PersonAuthorship 137793090 /api/authorship/137793090 Eid, Mohamed Hamdy ✉ [Hemida, Mohamed Hamdy Eid (Hydrogeology), szerző] Víz- és Környezetgazdálkodási Intézet (ME / MFK) 1 0.143 true false true Author 10080487 /api/author/10080487 Hemida Mohamed Hamdy Eid (Hydrogeology) Hemida Mohamed Hamdy Eid true true Eid Mohamed Hamdy true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 137793091 /api/authorship/137793091 Eissa, Mustafa 2 0.14285715 false false false Eissa Mustafa true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 137793092 /api/authorship/137793092 Mikita, Viktoria [Mikita, Viktória (Hidrogeológia), szerző] Víz- és Környezetgazdálkodási Intézet (ME / MFK) 3 0.143 false false false Author 10030108 /api/author/10030108 Mikita Viktória (Hidrogeológia) Mikita Viktória true 10030108 true Mikita Viktoria true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 137793093 /api/authorship/137793093 Bence, Czímer [Czímer, Bence (Hidrogeológus mérnök), szerző] Víz- és Környezetgazdálkodási Intézet (ME / MFK) 4 0.143 false false false Author 10090705 /api/author/10090705 Czímer Bence (Hidrogeológus mérnök) Czímer Bence true true Bence Czímer true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 137793094 /api/authorship/137793094 Palcsu, László [Palcsu, László (Nemesgáz-analitik...), szerző] HUN-REN Atommagkutató Intézet 5 0.14285715 false false false Author 10013199 /api/author/10013199 Palcsu László (Nemesgáz-analitika, izotóphidrológia) Palcsu László true 10013199 true Palcsu László true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 137793095 /api/authorship/137793095 Kovács, Attila [Kovács, Attila (Hidrogeológia), szerző] Víz- és Környezetgazdálkodási Intézet (ME / MFK) 6 0.143 false false false Author 10013363 /api/author/10013363 Kovács Attila (Hidrogeológia) Kovács Attila true 10013363 true Kovács Attila true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PersonAuthorship 137793096 /api/authorship/137793096 Szűcs, Péter [Szűcs, Péter (Hidrogeológia, kú...), szerző] Víz- és Környezetgazdálkodási Intézet (ME / MFK) 7 0.143 false true false Author 10000736 /api/author/10000736 Szűcs Péter (Hidrogeológia, kúthidraulika) Szűcs Péter true 10000736 true Szűcs Péter true false false AuthorshipType 1 /api/authorshiptype/1 Szerző 0 true 0 true false true PublicationIdentifier 31968921 /api/publicationidentifier/31968921 DOI: 10.1007/s10040-026-03078-3 PlainSource 6 /api/publicationsource/6 DOI PublicationSourceType 10001 /api/publicationsourcetype/10001 DOI true true true DOI DOI https://doi.org/@@@ true true 6 true IDENTICAL 10.1007/s10040-026-03078-3 https://doi.org/10.1007/s10040-026-03078-3 false true PublicationIdentifier 31980955 /api/publicationidentifier/31980955 WoS: 001755279600001 PlainSource 1 /api/publicationsource/1 WoS PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true WoS WoS https://www.webofscience.com/wos/woscc/full-record/@@@ true true 1 true IDENTICAL 001755279600001 https://www.webofscience.com/wos/woscc/full-record/001755279600001 true true PublicationIdentifier 32227794 /api/publicationidentifier/32227794 Scopus: 105037875379 PlainSource 3 /api/publicationsource/3 Scopus PublicationSourceType 10003 /api/publicationsourcetype/10003 Indexelő adatbázis false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 105037875379 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-105037875379 true true PublicationIdentifier 31968922 /api/publicationidentifier/31968922 Egyéb URL: https://link.springer.com/10.1007/s10040-026-03078-3 PlainSource 40 /api/publicationsource/40 Egyéb URL PublicationSourceType 10006 /api/publicationsourcetype/10006 Link true true true Egyéb URL Other URL @@@ true true 40 true https://link.springer.com/10.1007/s10040-026-03078-3 https://link.springer.com/10.1007/s10040-026-03078-3 false true MtaRating 11435237 /api/mtarating/11435237 X.
