Abstract
In this paper we study the evolution of spatially homogeneous and anisotropic Bianchi type-I Universe models with the cosmological constant, Λ, and filled with nonlinearviscous fluid. The dynamical equations for these models are obtained and solved for some special cases. We calculate

the statefinder parameters for the models and display them in the s-r-plane.
