Estimating groundwater recharge remains an exceptionally challenging task for hydrologists, particularly in catchments characterized by forest-dominant land use and abundant steep hillslopes, where the storage and flow of groundwater are intricately tied to factors such as climate patterns and specific hydrological processes across diverse slopes. Here, we applied the Soil and Water Assessment Tool (SWAT) to evaluate the spatiotemporal variability and magnitudes of shallow groundwater discharge and deep groundwater recharge to improve our understanding of precipitation patterns and terrain impact on groundwater recharge. Our results revealed significant variability in shallow groundwater discharge and deep groundwater recharge across the catchment, with average annual values of 305 mm/year and 165.77 mm/year, respectively. The spatiotemporal variability of these groundwater components was primarily influenced by climatic conditions; however, within the catchment zones, slopes below 20% made significant contributions to the observed variations. The upper mountainous areas influenced by snow contributed significantly to the catchment's groundwater resources, accounting for 42% of the shallow groundwater discharge and 46% of the deep groundwater recharge. In contrast, urbanized lowland areas made much smaller contributions—13% of shallow groundwater discharge and 5% of deep groundwater recharge. Notably, during the driest year, both shallow groundwater discharge and deep groundwater recharge were insufficient to meet the daily water demand of the catchment, indicating the need for alternative water storage methods such as reservoirs. These findings offer insights for decision-making to enhance groundwater resource resilience in the region.","subitem_description_language":"en"},{"subitem_description":"This research was supported by the Asia-Pacific Network for Global Change Research (APN) under Grant No. CRRP 2019-09MY-Onodera (funder ID: https://doi.org/10.13039/100005536).","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_1617186901218":{"attribute_name":"Funding Reference","attribute_value_mlt":[{"subitem_award_numbers":{"subitem_award_number":"21H03650","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-21H03650/"},"subitem_award_titles":[{"subitem_award_title":"流域水・物質輸送に伴う藻場変遷過程の解明：生態系サービスの定量化と活用に向けて","subitem_award_title_language":"ja"}],"subitem_funder_names":[{"subitem_funder_name":"日本学術振興会","subitem_funder_name_language":"ja"}]},{"subitem_award_numbers":{"subitem_award_number":"20KK0262","subitem_award_uri":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20KK0262/"},"subitem_award_titles":[{"subitem_award_title":"Transition process of seagrass-seaweed meadows driven by water and material transport from watersheds: Toward quantification and utilization of the ecosystem services","subitem_award_title_language":"ja"}],"subitem_funder_names":[{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]},{"subitem_award_titles":[{"subitem_award_title":"地下水環境学と沿岸生態学の融合と深化：ブレークスルーに向けた新規アプローチの導入"}],"subitem_funder_names":[{"subitem_funder_name":"日本学術振興会","subitem_funder_name_language":"ja"}]},{"subitem_award_titles":[{"subitem_award_title":"Integration and deepening of groundwater environmentology and coastal ecology: Application of new approaches for the breakthrough"}],"subitem_funder_names":[{"subitem_funder_name":"Japan Society for the Promotion of Science","subitem_funder_name_language":"en"}]}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"101150"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2024-03-09","bibliographicIssueDateType":"Issued"},"bibliographicPageStart":"101150","bibliographicVolumeNumber":"25","bibliographic_titles":[{"bibliographic_title":"Groundwater for Sustainable Development","bibliographic_titleLang":"en"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.gsd.2024.101150","subitem_relation_type_select":"DOI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2026-03-09"}],"displaytype":"simple","fileDate":[{"fileDateType":"Available","fileDateValue":"2026-03-09"}],"filename":"GSD_25_101150.pdf","filesize":[{"value":"2.2 MB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2006946/files/GSD_25_101150.pdf"},"version_id":"00c59852-2def-4819-88bb-0a3175fa1657"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"55831"},"item_1732772494514":{"attribute_name":"備考","attribute_value":"The full-text file will be made open to the public on 9 March 2026 in accordance with publisher's 'Terms and Conditions for Self-Archiving'"},"item_title":"Spatiotemporal shallow and deep groundwater dynamics in a forested mountain catchment with diverse slope gradients, western Japan","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-12-09"},"publish_date":"2024-12-09","publish_status":"0","recid":"2006946","relation_version_is_last":true,"title":["Spatiotemporal shallow and deep groundwater dynamics in a forested mountain catchment with diverse slope gradients, western Japan"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-21T08:47:28.253165+00:00"}
