    Abstract: 本研究乃為發展一套計算沙丘侵蝕率的數值模 式,以探討波浪特性對沙丘侵蝕率之影響.根據 Eldeman(1968,1972),Hughes &Chiu(1979),Dean & Galvin(1976)及 Silvester(1984)的研究,黃及林(1990)假設一平衡穩定 沙灘其海底坡度維持不變,利用Hibberd &Peregrine( 1979)的溯升模式,配合輸沙方程式,研究前灘區漂 沙運移的情形,Lin(1991)亦依此模式初步探討沙丘 侵蝕率.本研究假設溯升及回降(Uprush & Backwash)並 不相互影響彼此之輸沙能力,改良黃及林(1990)和 Lin(1991)之數值模式,並考慮沙丘因侵蝕而後退的 情形,發展一套計算沙丘侵蝕率的數值模式.第一年將黃及林(1990)和Lin(1991)之數值模式作適度 的修正,並進行模型實驗探討薄層流輸沙之情形.在第二年的研究中,將以實驗來探討沙丘因侵蝕 而後退之情況,藉以修正數值模式.
