   This run analyses the three dimensional secondary  flow  pattern
   generated  by  a  canopy.  The  Prandtl  mixing  length model in
   conjunction with the power-law  velocity  profile  in  a  stable
   athmosfere   are   used   to  evalute  the  turbulent  viscosity
   distribution. The latter, the non-uniform velocity inlet profile
   and  plant  airflow  interaction  are  introduced  through PLANT
   generated  GROUND  codings.  Interesting  variants  include  the
   comparison  with  the  K-E  model  simulations  presented  by U.
   Svensson and  K.  Haeggkvist  in  J.  of  Wind  Engineering  and
   Industrial Aerodynamics, 35, 1990, pp. 201-211
