In this study, the physical environment was measured in order to examine just how the river precipice is the supply source of the gravel. As a result, no significant differences were indicated in the river width, velocity and the radius but the river depth in the meander with river cliff is significantly shallower than the one without river cliff and the size of gravel in the meander with cliff is significantly larger than the one without river cliff. Additionally, there was no obvious migration of gravel by freshet of snow melting. In conclusion, it was extrapolated that the gravel was provided not from upstream but by the eroding of the river cliff.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"15","subitem_description_type":"Other"}]},"item_1_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00005049274","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"短報","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Note","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学大学院生物産業学研究科生物産業学専攻
