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 twodimensional (2D) test cases for densitydependent groundwater flow and solute transport simulators. Unlike existing densitydependent model benchmarks, these problems have welldefined 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 fluidfilled porous layer in which fluid density decreases with depth. The proposed...

Inverse modeling studies employing data collected from the classic Henry seawater intrusion problem give insight into several important aspects of inverse modeling of seawater intrusion problems and effective measurement strategies for estimation of parameters for seawater intrusion. Despite the simplicity of the Henry problem, it embodies the behavior of a typical seawater intrusion situation in a single aquifer. Data collected from the numerical problem solution are employed without added noise in order to focus on the aspects of inverse modeling strategies dictated by the physics of variabledensity flow and solute transport during seawater intrusion. Covariances of model parameters that can be estimated are...
