The surface heat balance, which is composed of net radiation, sensible and latent heat fluxes, is a non-linear function of water temperature. So a differential equation concerning river water temperature is non-linear. The surface heat balance has been treated as a regression quadratic equation of water temperature in some papers.\nIn this paper the following three trajectories of solution for one-dimensional non-linear heat balance equation are shown using Bernoulli\u0027s equation with a threshold value, convergence to an equilibrium temperature, constant value and divergence. The difference between non-linear and linear analyses of the river water temperature is investigated under some combinations of hydrological and meteorological elements.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "42312", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SADO, Kimiteru"}]}, {"nameIdentifiers": [{"nameIdentifier": "42313", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "SUGIYAMA, Ichiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "42314", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "NAKAO, Takashi"}]}]}, "item_3_publisher_212": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u516c\u76ca\u793e\u56e3\u6cd5\u4eba \u571f\u6728\u5b66\u4f1a"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://doi.org/10.2208/prohe.45.991", "subitem_relation_type_select": "DOI"}}]}, "item_3_rights_192": {"attribute_name": "\u6a29\u5229", "attribute_value_mlt": [{"subitem_rights": "c2001 \u516c\u76ca\u793e\u56e3\u6cd5\u4eba \u571f\u6728\u5b66\u4f1a"}]}, "item_3_select_195": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_3_subject_196": {"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": "\u4f50\u6e21, \u516c\u660e"}], "nameIdentifiers": [{"nameIdentifier": "42309", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u6749\u5c71, \u4e00\u90ce"}], "nameIdentifiers": [{"nameIdentifier": "42310", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "\u4e2d\u5c3e, \u9686\u5fd7"}], "nameIdentifiers": [{"nameIdentifier": "44842", "nameIdentifierScheme": "WEKO"}, {"nameIdentifier": "1000060101523 ", "nameIdentifierScheme": "NRID", "nameIdentifierURI": "http://rns.nii.ac.jp/d/nr/1000060101523 "}]}]}, "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": "2001_\u6cb3\u5ddd\u6c34\u6e29\u306e\u975e\u7dda\u5f62\u89e3\u6790.pdf", "filesize": [{"value": "753.5 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 753500.0, "url": {"label": "2001_\u6cb3\u5ddd\u6c34\u6e29\u306e\u975e\u7dda\u5f62\u89e3\u6790.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/8103/files/2001_\u6cb3\u5ddd\u6c34\u6e29\u306e\u975e\u7dda\u5f62\u89e3\u6790.pdf"}, "version_id": "7d6a125e-568a-4e4d-9668-b9aa428a559c"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "river water temperature", "subitem_subject_scheme": "Other"}, {"subitem_subject": "non-linear analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "threshold value", "subitem_subject_scheme": "Other"}, {"subitem_subject": "equilibrium temperature", "subitem_subject_scheme": "Other"}, {"subitem_subject": "divergence", "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": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "\u6cb3\u5ddd\u6c34\u6e29\u306e\u975e\u7dda\u5f62\u89e3\u6790", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "\u6cb3\u5ddd\u6c34\u6e29\u306e\u975e\u7dda\u5f62\u89e3\u6790"}]}, "item_type_id": "3", "owner": "1", "path": ["1"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/8103", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2016-03-11"}, "publish_date": "2016-03-11", "publish_status": "0", "recid": "8103", "relation": {}, "relation_version_is_last": true, "title": ["\u6cb3\u5ddd\u6c34\u6e29\u306e\u975e\u7dda\u5f62\u89e3\u6790"], "weko_shared_id": 3}
