  In this paper subgrid multiscale stabilized finite element method for
Advection-Diffusion-Reaction (ADR) equation coupled with Stokes-Darcy flow
problem has been studied. Here the advection velocity involved in ADR equation
obeys Stokes-Darcy flow equation. In this study the approach of algebraic
approximation of stabilization parameter has been considered. Further apriori
error estimation has been elaborately carried out.
