Abstract: We develop an effective theory of pulse propagation in a nonlinear {\it and}disordered medium. The theory is formulated in terms of a nonlinear diffusionequation. Despite its apparent simplicity this equation describes novelphenomena which we refer to as -locked explosion- and -diffusive- collapse. Theequation can be applied to such distinct physical systems as laser beamspropagating in disordered photonic crystals or Bose-Einstein condensatesexpanding in a disordered environment.
