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

Figure 5

Simulated results of current velocity u versus the flow distance L in the streamline direction of water flume for measuring points at different water depths (a) and its evolution process (b). 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.
