Abstract: We study the Korteweg-de Vries (KdV) equation with external noise and compare our numerical simulations to known theoretical results. By using a modification of the Zabusky-Kruskal finite difference scheme, we are able to generate numerical solutions to the stochastic KdV. We look at the large time behavior of the stochastic KdV and verify the diffusion of solitons. We find that the predicted large time behavior of the perturbed solution is not easily confirmed in the simulations as the initial soliton diffuses and is lost amidst the background noise long before the asymptotic limit is reached.
