Abstract: We study the asymptotic behavior of solutions of the initial value problem for a conservation law $ {u_t} + f{(u)_x} = 0$. It is assumed that the initial data agrees with the Riemann data for $ \vert x\vert$ large. We show that the solution approaches that of the corresponding Riemann problem at algebraic rates.
