A Meshless WCSPH Boundary Treatment for Open-Channel Flow over Small-Scale Rough Bed

Figure 6

Numerical current velocity in the streamline direction u (a) and its relative standard deviation value RSD (b) versus flow time t for measuring points at different water depths. The solid line represents particle spacing of 0.002 m, the dashed line represents particle spacing of 0.003 m, and the dotted line represents particle spacing of 0.004 m.
