Entry: Ursell number
URI: https://registry.epos-eu.org/ncl/FAIR-Incubator/tcs-TSU/70
In the long wave approximation, the Ursell number provides a measure of the importance of the non-linear terms in the equations. It is the product of two ratios. The first is the ratio of the tsunami amplitude to the local sea depth; the second is the ratio of the wavelength to the local sea depth, raised to the power of two. For "small" Ursell numbers, linear wave theory holds. For large Ursell numbers, non-linear terms must be taken into account.
