DESCRIPTION:Dr. D. Newman\, Universidad Carlos III de Madrid / Univ. of A
 laska Fairbanks - Physics Dept\nRecently\, much progress has been made tow
 ard understanding the fundamental dynamics of turbulent transport in the p
 resence of sheared flows. The insights have among other methods come from 
 following Lagrangian trajectories using both gyrokinetic simulations of IT
 G turbulence and fluid models of drift-wave turbulence. Using these tools\
 , the impact of both sheared flows and simple diamagnetic drifts on the dy
 namics of the transport is investigated using numerical simulations of 2D-
 turbulence in slab geometry with the BETA code and in 3-D turbulence with 
 the UCAN gyrokinetic code. The changes in the dynamics with these flows is
  found to be very significant with the transport in some cases becoming ra
 ther non-diffusive.  The various impacts of flows on turbulent transport 
 will be reviewed and the new transport dynamics and their possible uses wi
 ll be discussed.
