| Summary: | 碩士 === 淡江大學 === 水資源及環境工程所 === 82 === The study is done with a rectangular section of water tank with
the sizes of length、width and height is 30 m、0.8 m and 0.8 m,
respectively.We make waves with a piston-type wave maker.Then
we use different kinds of slopes、wave heights and wave periods
pass through the channel with a sandy bed. During the waves
pass by,it will change the bed of the channel.We consider
situations among the different wave conditions and slopes to
investigate the sedimentation on this sloping sandy beach.
Finally,we also discuss the effects of smooth fixed-shape bed
and rough fixed-shape bed on the wave run-up.We also compared
and discussed the equations,which were taken by some researcher
with the results of this study.
