  Numerical simulations of L-mode plasma turbulence in the Scrape Off Layer of
MAST are presented. Relevant features of the boundary plasma, such as the
thickness of the density layer or the statistics of the fluctuations are
related to the edge density and temperature, plasma current and parallel
connection length. It is found that the density profile is weakly affected by
the edge density, it broadens when the current or the temperature are decreased
while the connection length has the opposite effect. The statistics of the
turbulence is relatively insensitive to variations of all the edge parameters
and show a certain degree of universality. Effective transport coefficients are
calculated for several plasma conditions and display a strong nonlinear
dependence on the parameters and on the radial variable. Finally, it is shown
how the perpendicular particle fluxes in the Scrape Off Layer are related to
the edge parameters.
