Description: SHARP is a specialized GW flow code to simulate freshwater and saltwater flow
separated by a sharp interface in layered coastal aquifer systems. It is quasi-3D according to its
authors (2D plane flow in each aquifer layer).
Numerical method: An implicit finite-difference discretization scheme, central in space and
backward in time (fully implicit) is used to solve the freshwater and saltwater flow equations for
each model layer. Spatial discretization is achieved using a block-centered finite-difference grid
that allows for variable grid spacing. In the central difference approximations for space
derivatives, the thicknesses at grid block bounda...
