  We investigate disorder induced localization in the presence of nonlinearity
and curvature. We numerically analyze the time-resolved three-dimensional
expansion of a wave-packet in a bended cigar shaped potential with a focusing
Kerr-like interaction term and Gaussian disorder. We report on a
self-consistent analytical theory in which randomness, nonlinearity and
geometry are determined by a single scaling parameter, and show that curvature
enhances localization.
