The relationship between river width and discharge was also expressed in a theoretical formula by Ikeda and Parker (1986) that considers static stability at the boundary of flow in a straight gravel river at dynamic equilibrium. Yamamoto examined the reaction of a river channel to artificial expansion of river width. However, previous research has not determined which factors regulate the formation of distributaries in a river\u0027s alluvial fan and near its mouth. This paper aims at clarifying the conditions under which distributaries form by performing stability analysis of the riverbed in the transverse direction. The stability analysis had been developed to model medium-scale bar formation. The study results show that flow regime is the determining factor in distributary formation.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_32": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u793e\u56e3\u6cd5\u4eba\u5730\u76e4\u5de5\u5b66\u4f1a"}]}, "item_5_relation_11": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.11345/japannctam.57.0.141.0", "subitem_relation_type_select": "DOI"}}]}, "item_5_rights_12": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "c 2008 \u516c\u76ca\u793e\u56e3\u6cd5\u4eba \u5730\u76e4\u5de5\u5b66\u4f1a"}]}, "item_5_select_15": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_5_subject_16": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "510", "subitem_subject_scheme": "NDC"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u6e21\u908a, \u5eb7\u7384"}], "nameIdentifiers": [{"nameIdentifier": "44829", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000000344424 ", "nameIdentifierScheme": "NRID", "nameIdentifierURI": "http://rns.nii.ac.jp/d/nr/1000000344424 "}]}, {"creatorNames": [{"creatorName": "Watanabe, Yasuharu", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "41966", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "2008-06.pdf", "filesize": [{"value": "818.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 818900.0, "url": {"label": "2008-06.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/8060/files/2008-06.pdf"}, "version_id": "2e5daf32-ba69-4916-9bdc-7193833bfdcb"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "\u5b89\u5b9a\u89e3\u6790", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u5ddd\u5e45", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u6d3e\u5ddd", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u81ea\u5f8b\u5f62\u6210,", "subitem_subject_scheme": "Other"}, {"subitem_subject": "\u6cb3\u5ddd\u5730\u5f62", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Stability analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "River Width", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Distributary", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Self-adjustment", "subitem_subject_scheme": "Other"}, {"subitem_subject": "River Morphology", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "conference paper", "resourceuri": "http://purl.org/coar/resource_type/c_5794"}]}, "item_title": "\u5ddd\u5e45\u304a\u3088\u3073\u6d3e\u5ddd\u306e\u81ea\u5f8b\u5f62\u6210\u6a5f\u69cb\u306b\u95a2\u3059\u308b\u5b89\u5b9a\u89e3\u6790", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u5ddd\u5e45\u304a\u3088\u3073\u6d3e\u5ddd\u306e\u81ea\u5f8b\u5f62\u6210\u6a5f\u69cb\u306b\u95a2\u3059\u308b\u5b89\u5b9a\u89e3\u6790"}]}, "item_type_id": "5", "owner": "1", "path": ["10"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/8060", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2016-01-28"}, "publish_date": "2016-01-28", "publish_status": "0", "recid": "8060", "relation": {}, "relation_version_is_last": true, "title": ["\u5ddd\u5e45\u304a\u3088\u3073\u6d3e\u5ddd\u306e\u81ea\u5f8b\u5f62\u6210\u6a5f\u69cb\u306b\u95a2\u3059\u308b\u5b89\u5b9a\u89e3\u6790"], "weko_shared_id": 3}
