This report summarizes four lines along which the finite-difference (FD) method has been recently (in 1995/96) extended: (i) irregular grids, (ii) non-planar free surface, (iii) hybrid methods, and (iv) approximate absorption treatment. While the former two have been described in a great detail in a diploma thesis (Oprsal, 1996), and will be submitted as a methodical paper (Oprsal and Zahradnik, in preparation), the latter two will be presented together with a practical application at a conference (Caserta and Zahradnik, 1996).
