... Longuet– Higgins in [32, 33]. In this theory the flow is periodic in the alongshore direction and, most importantly, the incoming wave forms a slowly varying wavetrain with constant amplitude in the alongshore ... lasting change in the mean flow. It is also clear that the net residual forcing points in the direction of p. So there is no intrinsic link between wave diss...

... vorticity, ζ, the streamlines are hyperbolic as shown in Fig. 2.8 and the continuous stretching along the unsta- ble manifold of the stagnation point of the flow induces instability. The instability Fig. ... Neglecting the torsion, the obtained flow is therefore similar to the one studied previously. Indeed, the normal to the osculating plane (so-called binormal) is prec...
