The Unsymmetric Lanczos Reduction (ULR) method is developed to solve the ΓΏnite-element-based solution to the contaminant transport problem. The method sometimes su ers from breakdown when at some step division by a pivot which is zero or near zero, causes numerical instability. In this paper, the Ma
