We develop an algorithm for estimating the local Sobolev regularity index
of a given function by monitoring the decay rate of its Legendre expansion
coefficients. On the basis of these local regularities, we design and
implement an hp--adaptive finite element method based on employing
discontinuous piecewise polynomials, for the approximation of nonlinear
systems of hyperbolic conservation laws. The performance of the proposed
adaptive strategy is demonstrated numerically.
