We characterise wetland distribution, seasonality and persistence and evaluate their spatial association with glaciers and seasonal snow. Using Landsat 7 and 8 imagery, we build three-month seasonal land cover maps from 2013 to 2022 using a Random Forest classification and an Albedo Retrieval approach.\r\nNew hydrological insights for the region: Wetland area decreases by 38% from the end of the wet season (October to December) to the end of the dry season (July to September). Pixel transitions indicate that wetlands primarily transform to and from agricultural and pasture lands. Highly persistent wetlands are located above 4600 m a.s.l. and closer to glaciers than less persistent wetlands. We identified three wetland seasonal drying patterns. Basins with delayed and slow dry-out wetlands were more common at higher elevations but were not always in glacierised catchments, suggesting meltwater may maintain wetlands in the early dry season. We provide the first large-scale picture of wetland seasonality, and the basis for modelling the processes that sustain wetlands in tropical high mountains."}],"department":[{"_id":"FrPe"}],"date_published":"2026-07-30T00:00:00Z","oa":1,"language":[{"iso":"eng"}],"article_processing_charge":"Yes","volume":67,"date_updated":"2026-08-11T06:48:28Z","das_tickbox":"1","supplementarymaterial":"yes","quality_controlled":"1","publication_identifier":{"eissn":["2214-5818"]},"fulldoi":"https://doi.org/10.1016/j.ejrh.2026.103808","oa_version":"Published Version","researchdata_availability":"yes","day":"30","year":"2026","title":"Andean wetlands: Seasonal variability and their interactions with the cryosphere","doi":"10.1016/j.ejrh.2026.103808","_id":"22677","acknowledgement":"Joshua Castro acknowledges the support and funding of the Swiss Government Excellence Scholarships (ESKAS-Nr: 2022.0416) and the Doc.

However, there remains a lack of understanding of snow processes and quantification of the contribution of melt to runoff. Here we apply a distributed glacio-hydrological model over the Rio Santa basin to disentangle the role of the cryosphere in the Andean water cycle. Only at the highest elevations (>5000 m a.s.l.) is the snow cover continuous; at lower elevations, the snowpack is thin and ephemeral, with rapid cycles of snowfall and melt. Due to the large catchment area affected by ephemeral snow, its contribution to catchment inputs is substantial (23% and 38% in the wet and dry season, respectively). Ice melt is crucial in the mid-dry season (up to 44% of inputs). Our results improve estimates of water fluxes and call for further process-based modelling across the Andes.","lang":"eng"}],"intvolume":"         6","department":[{"_id":"FrPe"}],"date_published":"2025-06-05T00:00:00Z","OA_type":"gold","type":"journal_article","author":[{"last_name":"Fyffe","id":"001b0422-8d15-11ed-bc51-cab6c037a228","full_name":"Fyffe, Catriona Louise","first_name":"Catriona Louise"},{"last_name":"Potter","full_name":"Potter, Emily","first_name":"Emily"},{"last_name":"Miles","first_name":"Evan","full_name":"Miles, Evan"},{"id":"3caa3f91-1f03-11ee-96ce-e0e553054d6e","last_name":"Shaw","first_name":"Thomas","full_name":"Shaw, Thomas","orcid":"0000-0001-7640-6152"},{"last_name":"Mccarthy","id":"22a2674a-61ce-11ee-94b5-d18813baf16f","full_name":"Mccarthy, Michael","first_name":"Michael"},{"first_name":"Andrew","full_name":"Orr, Andrew","last_name":"Orr"},{"first_name":"Edwin","full_name":"Loarte, Edwin","last_name":"Loarte"},{"last_name":"Medina","full_name":"Medina, Katy","first_name":"Katy"},{"last_name":"Fatichi","first_name":"Simone","full_name":"Fatichi, Simone"},{"last_name":"Hellström","first_name":"Rob","full_name":"Hellström, Rob"},{"full_name":"Baraer, Michel","first_name":"Michel","last_name":"Baraer"},{"last_name":"Mateo","first_name":"Emilio","full_name":"Mateo, Emilio"},{"first_name":"Alejo","full_name":"Cochachin, Alejo","last_name":"Cochachin"},{"first_name":"Matthew","full_name":"Westoby, Matthew","last_name":"Westoby"},{"first_name":"Francesca","full_name":"Pellicciotti, Francesca","orcid":"0000-0002-5554-8087","id":"b28f055a-81ea-11ed-b70c-a9fe7f7b0e70","last_name":"Pellicciotti"}],"article_number":"434","date_created":"2025-06-15T22:01:28Z","file_date_updated":"2025-06-23T06:41:15Z","citation":{"ista":"Fyffe CL, Potter E, Miles E, Shaw T, McCarthy M, Orr A, Loarte E, Medina K, Fatichi S, Hellström R, Baraer M, Mateo E, Cochachin A, Westoby M, Pellicciotti F. 2025.
