  Bianchi type V bulk viscous fluid cosmological models are investigated with
dynamic cosmological term $\Lambda(t)$. Using a generation technique (Camci
{\it et al.}, 2001), it is shown that the Einstein's field equations are
solvable for any arbitrary cosmic scale function. Solutions for particular
forms of cosmic scale functions are also obtained. The cosmological constant is
found to be decreasing function of time, which is supported by results from
recent type Ia supernovae observations. Some physical and geometrical aspects
of the models are also discussed.
