In this paper we discuss an adaptive method for the computation of discontinuous solutions of hyperbolic conservation laws. In each time level we use techniques coming from interpolatory multiresolution analyses for detecting discontinuities of the solution. The adaptive scheme uses first order upwind flux computation in the immediate neighbourhood of these irregularities. Since the differential equation holds in the smoothness domain, we follow the characteristics in the time marching procedure at grid points in that domain.
