Analogy between equilibrium beach profiles and closed universes

We reformulate the variational problem describing equilibrium beach profiles in the thermodynamic approach of Jenkins and Inman [J. Geophys. Res.: Oceans 111, C02003 (2006)10.1029/2005JC002899]. A first integral of the resulting Euler-Lagrange equation coincides formally with the Friedmann equation...
