   This case is a part of the main project to predict turbulent and
   two-phase flows at the town scale. It is concerned with the snow
   fall  in the street canyon between one elevated building and its
   high-rise neighbour  block.  PLANT  is  used  to  introduce  the
   influences  of  gas and snow concentration near the road surface
   to the source of vehicular exhaust pollution.
