Table 1.

Meshes used for the grid-sensitivity assessment and predicted maximum local scour depth $S_{max}$ at $t = 3600$ s. Here, $N_{x} \times N_{y} \times N_{z}$ denotes the background grid resolution and N is the final number of control volumes. The percentage difference $Δ S$ is computed relative to the fine-mesh result

Mesh	$N_{x} \times N_{y} \times N_{z}$	N (cells)	$S_{max}$ ⁠: m	$Δ S$ ⁠: %
Coarse	$250 \times 32 \times 75$	535 206	0.047	23.0
Medium	$400 \times 50 \times 120$	2 145 708	0.058	4.92
Fine	$600 \times 75 \times 180$	7 246 182	0.061	0
