Trapping rates of suspended sediment into the trap were quantified using grass particles with several size of a sediment intake and drain hole, and drain mesh aperture in uniform flow.<br>&nbsp;Two neashore measurements were conducted to examine practicability of the trap. In Amitori bay, Iriomote Island, the traps were installed at two site in the bay to measure movements of silty sediments in coral reef. In an estuarine tidal flat, Rokujo-gata, a field measurement of sediment transport was conducted by using of the sediment traps to investigate bathymetric stability and sediment dynamics in a winter season.","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/jscejoe.72.I_922"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"岡辺 拓巳","creatorNameLang":"ja"},{"creatorName":"OKABE Takumi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"青木 勇介","creatorNameLang":"ja"},{"creatorName":"AOKI Yusuke","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"加藤 茂","creatorNameLang":"ja"},{"creatorName":"KATO Shigeru","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"村上 智一","creatorNameLang":"ja"},{"creatorName":"MURAKAMI Tomokazu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"下川 信也","creatorNameLang":"ja"},{"creatorName":"SHIMOKAWA Shinya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"河野 裕美","creatorNameLang":"ja"},{"creatorName":"KONO Hiromi","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"円筒型捕砂器の特性評価と浅海域における漂砂観測への適用","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"円筒型捕砂器の特性評価と浅海域における漂砂観測への適用","subitem_title_language":"ja"},{"subitem_title":"EXPERIMENTAL EVALUATION AND FIELD APPLICATIONS OF A CYLINDRICAL SEDIMENT TRAP FOR SUSPENDED SEDIMENT","subitem_title_language":"en"}]},"item_type_id":"40001","owner":"1","path":["1670839190650"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-04-27"},"publish_date":"2023-04-27","publish_status":"0","recid":"6097","relation_version_is_last":true,"title":["円筒型捕砂器の特性評価と浅海域における漂砂観測への適用"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-04-27T05:19:49.238634+00:00"}
