Onshore sheetflow sand transport enhanced by small onshore currents superimposed to skewed velocities KYI KYI LWIN Haijiang LIU Shinji SATO To answer the question whether the additional net onshore current contributes to a larger onshore net rate and to investigate the behavior of mean flow velocity profiles, a series of experiments was performed in the oscillatory flow tunnel and measurements of the net sand transport rate were conducted under asymmetric waves superimposed with an onshore current. The information of particle velocity at high concentration in the sheet flow was measured by means of PIV technique. The asymmetric flows with a wave period of 5 s and a maximum onshore velocity umax varying from 0.8 to 1.6 m/s have been applied for three well-sorted sands with different medium sand sizes. The sediment net transport rate was measured. Results show that, the onshore streaming enhanced the onshore sheetflow net transport by different extents. The streaming-induced net transport rate is found to be related to the free-stream velocity and the sand size. http://hdl.handle.net/20.500.12678/0000007217 https://meral.edu.mm/records/7217
