Because a linear relationship was found between the mean (mu) and standard deviation (sigma) of pilodyn penetration depth, mean penetration depth was taken as the indicator of deterioration, and relationships with check dam structural features and climate data recorded by AMEDAS were investigated. Multiple linear regression analysis revealed that temperature, climate index (CI) computed from rain days, warmth index computed from daily and annual mean air temperature, and altitude were the climate variables with the most effect on the rate of decay. With regard to dam structural features, factors such as specific discharge rate, water through width, dam length, and dam height had the most effect. Accordingly, in an effort to summarize the effects of climatic conditions and structural features, CI, altitude, and dam height were extracted as the most significant explanatory variables, and a formula for prediction of mu was obtained for each factor for up to 5 years post construction. The results showed that by taking into consideration regional conditions and calculating CI values from AMEDAS data, it is possible to predict the extent of decay of wooden check dams.", "subitem_description_language": "en", "subitem_description_type": "Other"}]}, "item_10001_publisher_8": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "SPRINGER JAPAN KK", "subitem_publisher_language": "en"}]}, "item_10001_relation_14": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "10.1007/s10310-013-0434-x"}}]}, "item_10001_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "1610-7403", "subitem_source_identifier_type": "EISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Hiromi Akita", "creatorNameLang": "ja"}, {"creatorName": "Hiromi Akita", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hikaru Kitahara", "creatorNameLang": "ja"}, {"creatorName": "Hikaru Kitahara", "creatorNameLang": "en"}]}, {"creatorNames": [{"creatorName": "Hiroshi Ono", "creatorNameLang": "ja"}, {"creatorName": "Hiroshi Ono", "creatorNameLang": "en"}]}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_title": "Effect of climate and structure on the progression of wooden check dam decay", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Effect of climate and structure on the progression of wooden check dam decay", "subitem_title_language": "ja"}, {"subitem_title": "Effect of climate and structure on the progression of wooden check dam decay", "subitem_title_language": "en"}]}, "item_type_id": "40001", "owner": "10", "path": ["1670839190650"], "permalink_uri": "https://nied-repo.bosai.go.jp/records/4179", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2024-05-27"}, "publish_date": "2024-05-27", "publish_status": "0", "recid": "4179", "relation": {}, "relation_version_is_last": true, "title": ["Effect of climate and structure on the progression of wooden check dam decay"], "weko_shared_id": -1}
