Non rotating case, evolution of the second packet

We now consider the evolution of the second packet to asses the sensitivity to the initial condition, shown in fig. 8. At the end of the first cycle, the pycnocline is still depressed in the middle of the basin, while near the crest we have on the western side an upward bulge (B1), created by the recirculating flow during the flood phase, and a small bore propagating east (J2). They both move eastward, advected by the ebbing tide. The bulge evolves into a mode 2 wave (A2) when the ebb tide reaches its peak at $T=15$ and subsequently disintegate. The bore fades away. In the meanwhile, the flow on the top of the Bank evolves in way very similar to the first cycle. The main difference is that the jump is advected further downstream, reaching $x=32.5$ Km. The jump evolves into a bore like it did during the first cycle, albeit with a smaller amplitude (and consequently speed). The shoaling is also different. The velocity near the bottom does not become critical. Still, a V-shaped depression forms, with the leading edge traveling faster than the trailing edge, like during the first cycle, though shallower.
