Weatherill, Douglas, Simmons, Craig T, Voss, Clifford I, and Robinson, Neville I, 2004, Testing density-dependent groundwater models: two-dimensional steady state unstable convection in infinite, finite and inclined porous layers: Advances in Water Resources, v. 27, iss. 5, p. 547-562.

This study proposes the use of several problems of unstable steady state convection with variable fluid density in a porous layer of infinite horizontal extent as two-dimensional (2-D) test cases for density-dependent groundwater flow and solute transport simulators. Unlike existing density-dependent model benchmarks, these problems have well-defined stability criteria that are determined analytically. These analytical stability indicators can be compared with numerical model results to test the ability of a code to accurately simulate buoyancy driven flow and diffusion. The basic analytical solution is for a horizontally infinite fluid-filled porous layer in which fluid density decreases with depth. The proposed test problems include [...]
