SOLA-VOF was used to compute the undular bore evolution shown in Fig. 8. The
initial configuration in Fig. 8a consists of a uniform mesh of 20 cells in the horizontal
direction (6x = 0.6) and 8 cells in the vertical direction (Sy = 0.2). Fluid initially fills
the lowest live rows (depth 1.0) and is uniformly moving to the right with unit
velocity
