In-situ observations and numerical simulations indicate that periodic currents in the connecting channel are dominate in response to flood tidal and ebb tide, and the stagnation of river-origin and low-salinity water is often observed at the 10-cm surface layer in Funauki Bay. Continuum theory of momentum and mass transfer suggest that periodic currents and steady-state flows among the bays and ocean depend mainly on the differences of depth and length among the two bays. As a result of the geographical features, it is concluded that river-origin water likely stagnates in Funauki Bay over the long periods of time, compared to Shirahama Bay.","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/kaigan.72.I_1207"}}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉野 純","creatorNameLang":"ja"},{"creatorName":"YOSHINO Jun","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"村上 智一","creatorNameLang":"ja"},{"creatorName":"MURAKAMI Tomokazu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"鵜飼 亮行","creatorNameLang":"ja"},{"creatorName":"UKAI Akiyuki","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"河野 裕美","creatorNameLang":"ja"},{"creatorName":"KOHNO Hiroyoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"北 恵伍","creatorNameLang":"ja"},{"creatorName":"KITA Keigo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"下川 信也","creatorNameLang":"ja"},{"creatorName":"SHIMOKAWA Shinya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"崎原 健","creatorNameLang":"ja"},{"creatorName":"SAKIHARA Ken","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"水谷 晃","creatorNameLang":"ja"},{"creatorName":"MIZUTANI Akira","creatorNameLang":"en"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_title":"西表島白浜湾および船浮湾における海水交換過程に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"西表島白浜湾および船浮湾における海水交換過程に関する研究","subitem_title_language":"ja"},{"subitem_title":"SEAWATER EXCHANGE PROCESSES THROUGH THE BAYS OF SHIRAHAMA AND FUNAUKI IN IRIOMOTE ISLAND, OKINAWA, JAPAN","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":"3755","relation_version_is_last":true,"title":["西表島白浜湾および船浮湾における海水交換過程に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-04-27T05:19:58.267299+00:00"}
