This paper deals with the numerical solution of conservation laws in the two dimensional case using a novel compact implicit time discretization that enable applications of fast algebraic solvers. We present details for the second order accurate parametric scheme based on the finite volume method including simple variants of ENO (Essentially Non-Oscillatory) and WENO (Weighted Essentially Non-Oscillatory) approximations. We present numerical experiments for representative linear and nonlinear problems.
