Abstract : The nonlinear evolution of the Rayleigh-Taylor instability in the long wavelength limit is investigated for an incompressible fluid supported against gravity (or inertial forces) by a massless fluid and bounded above by a rigid wall. Shallow water approximation permits a solution for the motion of the interface without reference to the detailed motion of fluid in the interior. (Modified author abstract)
