[[alternative]]A laboratory study on the erosion rate of coastal dune on a sandy sloping beach

[[abstract]]本研究所進行之一系列沙丘侵蝕實驗的目的是探討沙丘侵蝕量在不同之波浪條件下的變化，本研究也針對沙質海灘上不同的沙丘位置對侵蝕量大小的影響也進行了討論。先前對沙丘侵蝕的數值模擬與實驗結果均與本實驗的數值相互比較與討論。沙丘前所形成之沙洲其尖銳度與波浪尖銳度的關係亦有所探討。[[abstract]]A laboratory tests are performed in order to study the quantities of dune erosion due to attacks of different wave condition. And the effects of different dune locations on a sloping beach are also investigated. The comparison and discussion between the former results of numerical scheme and laboratory tests are studied. The relation between wave steepness and the steepness of sand bar is also discussed.[[sponsorship]]台灣大學; 海洋工程委員會[[notice]]補正完畢[[conferencetype]]國內[[booktype]]紙本[[iscallforpapers]]Y[[conferencelocation]]臺北市, 臺
