Numerical Study of Wave- and Current-Induced Oscillatory Seabed Response near a Fully Buried Subsea Pipeline

Figure 16

Variation of the wave- and current-induced momentary liquefaction around the pipeline in a complete wave period (H = 1 m, T = 8 s, d = 7 m, and U = 0.4 m/s): (a) t = 0, (b) t = 1/4 T, (c) t = 1/2 T, and (d) t = 3/4 T.
