The channel geometry, i.e., the channel gradient, channel width, the step-pool dimensions, size and number of step particle, etc., were surveyed at 35 study reaches of eight small basins in Japan. The results show that the channel gradient, channel width, and particle size have various implications for the step-pool geometry. With regard to the longitudinal profile of a step, the relationship between the channel geometry, step wavelength and step-step drop differs from that reported by previous studies at high-gradient reaches (\u003e 0.15 gradientA). The channel width and particle size are important variables aff ecting the step wavelength and step-step drop. Step width, which is the transverse profile of a step, is about 6 times the mean size of the rocks that form the step, and it is probably controlled by the particle size and channel width. The pool geometry is likely to be related to the channel gradient, discharge, and particle size. The characteristics of the distribution and the geomAetry of the step-pool can be explained by three parameters (particle size, discharge, and channel gradient). Estimation formulae were developed, which estimate local average geometry of the step-pool with catchment area and channel gradient.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "163375", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Gonda, Yutaka"}]}, {"nameIdentifiers": [{"nameIdentifier": "163376", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Okazaki, Tatsuya"}]}, {"nameIdentifiers": [{"nameIdentifier": "163377", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Nishii, Yohei"}]}, {"nameIdentifiers": [{"nameIdentifier": "163378", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kawabe, Hiroshi"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学農学部"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "権田, 豊"}], "nameIdentifiers": [{"nameIdentifier": "163371", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "岡崎, 達也"}], "nameIdentifiers": [{"nameIdentifier": "163372", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "西井, 洋平"}], "nameIdentifiers": [{"nameIdentifier": "163373", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "川邉, 洋"}], "nameIdentifiers": [{"nameIdentifier": "163374", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "61(1)_67-93.pdf", "filesize": [{"value": "2.5 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 2500000.0, "url": {"label": "61(1)_67-93.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28398/files/61(1)_67-93.pdf"}, "version_id": "e8414233-5325-4199-b404-9b5e2c509d40"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Step-Pool", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Step形状", "subitem_subject_scheme": "Other"}, {"subitem_subject": "渓流", "subitem_subject_scheme": "Other"}, {"subitem_subject": "新潟県", "subitem_subject_scheme": "Other"}, {"subitem_subject": "三重県", "subitem_subject_scheme": "Other"}, {"subitem_subject": "河川", "subitem_subject_scheme": "Other"}, {"subitem_subject": "地形", "subitem_subject_scheme": "Other"}, {"subitem_subject": "channel morphology", "subitem_subject_scheme": "Other"}, {"subitem_subject": "mountain streams", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Niigata", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mie", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "山地河川におけるStep-Pool構造の形状及び分布特性", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "山地河川におけるStep-Pool構造の形状及び分布特性"}, {"subitem_title": "山地河川におけるStep-Pool構造の形状及び分布特性", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1600"], "permalink_uri": "http://hdl.handle.net/10191/13074", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-07-02"}, "publish_date": "2010-07-02", "publish_status": "0", "recid": "28398", "relation": {}, "relation_version_is_last": true, "title": ["山地河川におけるStep-Pool構造の形状及び分布特性"], "weko_shared_id": null}
