In the previous studies, one-dimensional seepage analysis models were assumed, and unsaturated seepage behaviors were simulated by setting the free drainage boundary condition at the bottom of the one-dimensional models. However, in the case of heavy rain, because of the observation rising groundwater level at a field slope, the simulation setting the free drainage boundary condition could not reproduce the field measurement data. In this study, the authors proposed a new method estimating the seepage analysis model including the boundary condition at the bottom of the one-dimensional model using merging particle filter, and the applicability of the proposed method was verified. As a result, the estimated seepage analysis model by data assimilation could reproduce the measurement data of not only numerical experiments but also field slope. Therefore, the availability of the proposed method simulating from the unsaturated condition to the saturated condition was verified.\u003c/p\u003e", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "公益社団法人 土木学会", "subitem_publisher_language": "ja"}, {"subitem_publisher": "Japan Society of Civil Engineers", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.2208/jscejge.76.1_52"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "2185-6516", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "伊藤真一", "creatorNameLang": "ja"}, {"creatorName": "Shinichi ITO", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "小田和広", "creatorNameLang": "ja"}, {"creatorName": "Kazuhiro ODA", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "小泉圭吾", "creatorNameLang": "ja"}, {"creatorName": "Keigo KOIZUMI", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "西村美紀", "creatorNameLang": "ja"}, {"creatorName": "Miki NISHIMURA", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "檀上徹", "creatorNameLang": "ja"}, {"creatorName": "Toru DANJO", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "酒匂一成", "creatorNameLang": "ja"}, {"creatorName": "Kazunari SAKO", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_title": "融合粒子フィルタを用いた境界条件を含む浸透解析モデルの推定手法の提案", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "融合粒子フィルタを用いた境界条件を含む浸透解析モデルの推定手法の提案", "subitem_title_language": "ja"}, {"subitem_title": "PROPOSAL OF THE METHOD ESTIMATING SEEPAGE ANALYSIS MODEL INCLUDING A BOUNDARY CONDITION USING MERGING PARTICLE FILTER", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "1", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/5594", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2023-03-30"}, "publish_date": "2023-03-30", "publish_status": "0", "recid": "5594", "relation": {}, "relation_version_is_last": true, "title": ["融合粒子フィルタを用いた境界条件を含む浸透解析モデルの推定手法の提案"], "weko_shared_id": -1}
