Abstract
This paper presents the experimental results on Eulerian mass transport which is induced by waves propagating on a sloping bottom . The measurements are carried out by laser Doppler velocimeter(LDV) in wave flume. A particular installation of measuring system is required to detect the boundary layer flow extremely close to the point of 0.15mm above the sloping bottom . From the experimental results , it is clear to see that the off-shore mass transport takes place inside the region from the proximity of bottom up to wave trough.Around the elevation of wave trough,the mass transport velocity changes its direction to on-shore raidly , and it reaches the maximun value at still water level , then it decreases to zero at crest.Further,the vertical distribution and similarity profile of Eulerian mass transport inside boundary layer are also obtained and discussed in this paper.
