Abstract
Suppose that we take a bin and gently and uniformly pour in a granular material.As the material in the bin builds up we can identify a surface and ask the question what is the magnitude of the fluctuation in the height of surface? Also of interst is the length scale of the surface fluctuations and how they behave dynamically as more material is added. We assume that particles are deposited uniformly. There is a weak flux i.e. there are no correlations between incoming particles. Particles settle gently so that there is no cooperative reorganization. These assumptions can be considered as part of the definition of the problem.
