数值模拟的M2潮流在凯尔特海与海平面降低了100米表明，潮流的两倍，目前的强大。这样的水流足以产生和维持现在在该地区发现的线性潮汐沙滩，作为垂死的底形。此外，在海平面下降100米，相对于今天的潮汐椭圆的主轴的顺时针旋转的指示是在正确的意义上，进一步与现代的例子积极维护线性潮汐沙洲的比较。
Numerical modelling of M2tidal streams in the Celtic Sea with a sea level lowered by 100 m indicates tidal currents about twice as strong as those at present. Such currents would have been sufficient to generate and maintain the linear tidal sand banks now found in that region as moribund bedforms. Furthermore, an indicated clockwise rotation of the major axes of the tidal ellipses at a sea level lowered by 100 m with respect to the present day is in the correct sense to further the comparison with modern examples of actively maintained linear tidal sand banks.
