The Korteweg-de Vries equation with a damping term and an external force term is studied. In the non-damping case, the evolution of soliton solution under Gaussian white nosie is explicitly shown. For large t, a height and a width of the soliton are proportional to t^<-3/2> and t^<3/2> respectively. The damping case is also discussed. A new idea for the analysis of the inhomogeneous soliton equation is presented.
