The influence of geometry fluctuations on lateral diffusions is investigated numerically on a simple 1D problem which presents the same kind of non-linearities as fully 2D situations. It is found that geometry fluctuations influence diffusions at all scales, including scales much larger than the characteristic scales of fluctuations. The effective large-scale description of these diffusions is also investigated and the possibility of introducing a renormalized diffusion coefficient is discussed.
