碩士 / 國立成功大學 / 水利及海洋工程學系 / 84 / The developments of the river delta were studied through
aseries of experiments in this study . To simplify
experimentalconditions,steady water and sediment supply were
considered.Atfirst,an experimental run was used to describe the
developmentof the delta.Then the temporal variation of shape
factor wereemployed to classify the development of delta into
three stages.In the first stage,delta developed mainly in its
length,which caused the shape factory reaching a peak.In the
second stage,delta advanced mainly in its width,which resulted
in the decayof the shape factor.In the third stage,the stream
channel var-iated severely,and the shape factor oscilated.In
three stages,the geometric similarity of the delta was analized
by using three topographic scales. The results of the similarity
analy-sis showed that the plane shape,cross section profiles of
thedelta were able to similated by the Gaussin and hyperbolic
fu-nction,respectively. Finally,the occurance of the stream
chan-nel was also studied and discussed.
