本文旨在利用一系列的室內動床實驗, 探討河川主導型河口形成三角
洲後, 受波浪作用之發展過程.在實驗設計上是根據臺灣之海域及水理條
件,考慮先形成以推移載為主作用之河口三角洲,爾後停止造流再加波浪造
成地形上之變化. 在現象上,首先利用受波作用後後之三角洲發展之平面
照片,縱斷面,橫斷面地形圖, 來描述三角洲受波作用後之發展過程.最後
在分析比較上,以三角洲中心軸長度, 最大寬度之擴張角,橫斷面寬度,橫
斷面中心淤積厚度,進行平面形態,橫斷面形態之幾何相似性分析. 由分析
之結果顯示其分別具明確之高斯函數,雙曲函數之特性.

The developments of the river delta under wave action were
studied througha series of experiment in the present study.
Firstly, to design experimentalconditions, we consider that only
the bed-load exit. Secondly,to consider waveaction but to
eliminate the condition of headwater. On phenomenon,we used
thedelta film, longitudinal and transverse profile that
changed with time todiscuss the developments of the delta
under wave action. Then, the length,maximun width expansion
angle, width, deposit depthwere used as characteristicvalue to
analyze the geometric similarity of the longitudinal and
transverseprofile of the delta. The resultof analysis showed
that the configuation ofthe delta could be describe by Gaussian
function in the plane forms and hyper-bolic function in the
tranverse section.
