The 1980–2024 period was chosen to enable long-term shoreline trend analysis using reliable satellite data, capturing both natural coastal dynamics and human-induced impacts, while aligning with key climatic and developmental phases affecting Gujarat and Odisha. Four coastal regions were analyzed: Pingleshwar (30.196 km) and Mandavi (31.439 km) in Gujarat, and Tandahar (30.229 km) and Satabhaya (30.443 km) in Odisha. These stretches represent diverse geomorphological settings and varying exposure to erosion and accretion, offering valuable insights into India’s eastern and western coastal dynamics. The analysis utilized the Digital Shoreline Analysis System (DSAS), applying End Point Rate (EPR), Linear Regression Rate (LRR), and Net Shoreline Movement (NSM) methods to assess shoreline change across intervals (1980–1990, 1990–2000, 2000–2010, and 2010–2024). In Gujarat, Pingleshwar showed a relatively balanced shoreline with minimal erosion and moderate accretion, with the highest erosion (− 139.99 m/year) during 1990–2000 and maximum accretion (84.07 m/year) during 1980–1990. Mandavi, however, faced significant erosion, particularly during 2010–2024, with rates peaking at − 888.28 m/year and no accretion observed during this period. In Odisha, Tandahar exhibited both erosion and accretion, with the highest erosion (− 235.48 m/year) during 1980–1990 and significant accretion (131.08 m/year) in the same interval. Satabhaya consistently experienced severe erosion, peaking at − 320.92 m/year during 1980–1990, with sporadic accretion, the highest being 119.92 m/year during 2010–2024. The overall analysis from 1980 to 2024 indicates that Mandavi and Satabhaya predominantly faced erosional activities, marking them as highly vulnerable. Conversely, Pingleshwar and Tandahar showed mixed erosion and accretion patterns, indicating more variable shoreline behavior. These discoveries underscore the importance of integrating DSAS techniques for longstanding shoreline monitoring and highlight the need for embattled coastal administration strategies to alleviate erosion, especially in vulnerable zones like Mandavi and Satabhaya. The study emphasizes the value of sustainable coastal protection measures informed by robust spatiotemporal data.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Coastal erosion and accretion trends in Gujarat and Odisha: A 4-decade shoreline study","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-09-23 01:36:00.060537","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Shoreline dynamics · DSAS · EPR · LRR · NSM ","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-09-16","DateCreate":"2025-09-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s12601-025-00227-9"},"refs":null,"anarec":{"AnaID":416715,"PubliDate":2025,"Pagination":"33","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72541,"SerRR":"Ocean Science Journal.
