A total of 6667 landslides were confirmed in the period from 1965 to 2000 based on seven temporal pairs of aerial photographs. Both the occurrence\nof landslides and discharge into the dam lake affect sediment yield, indicating that\nfluvial systems in Miyagawa Dam catchment are supply-limited with respect to\nsediment. Sediment yields are not only affected by the initial failed volume of\nlandslides but also the mobility of landslides and debris flows. In Miyagawa Dam\ncatchment, percentages of landslides reaching channels varied from 56% in 1997–2000\nto 75% in 1976-1981, and were correlated with maximum hourly rainfall. In addition,\nthe mobility of debris flows was higher during periods with high maximum\ninstantaneous discharge compared to lower discharge, suggesting that the water content\nboth in initially failed materials and transported sediment controlled their mobility.\nTopography also affected the mobility of landslides/debris flows. For catchments >0.1\nkm2, the percentage of channel network length impacted by debris flows decreased with\nincreasing catchment area due to reduced channel gradient. Thus, both the magnitude of\nrainfall-runoff events and catchment topography affect how landslide sediment contributes to sediment yield at the large catchment scale.Index terms: Hydrology (1800), Catchment (1804), Debris flow and landslides (1810), Hillslope geomorphology (1826); and Sediment transport (1862).\nKey words: landslide, debris flow, sediment budget, dam deposits, forest roads, and\nhillslope-channel linkages","subitem_description_type":"Abstract"}]},"item_5_identifier_34":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2241/90988"}]},"item_5_publisher_27":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Geophysical Union"}]},"item_5_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1029/2006JF000495","subitem_relation_type_select":"DOI"}}]},"item_5_relation_36":{"attribute_name":"シリーズ","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"F03012"}]}]},"item_5_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©2007 American Geophysical Union"}]},"item_5_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"author"}]},"item_5_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0148-0227","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11870087","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Imaizumi, Fumitoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sidle, Roy C."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-12-18"}],"displaytype":"detail","filename":"JGR_112-F3.pdf","filesize":[{"value":"267.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JGR_112-F3.pdf","url":"https://tsukuba.repo.nii.ac.jp/record/9272/files/JGR_112-F3.pdf"},"version_id":"75abc632-4c48-40a1-b45a-d353fb8c494f"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Linkage of sediment supply and transport processes in Miyagawa Dam catchment, Japan","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Linkage of sediment supply and transport processes in Miyagawa Dam catchment, Japan"}]},"item_type_id":"5","owner":"1","path":["325","206"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-09-20"},"publish_date":"2007-09-20","publish_status":"0","recid":"9272","relation_version_is_last":true,"title":["Linkage of sediment supply and transport processes in Miyagawa Dam catchment, Japan"],"weko_creator_id":"1","weko_shared_id":5},"updated":"2022-04-27T10:23:54.050287+00:00"}
