Presented is a class of nonlinear partial differential equations which admit a reduction to tractable nonlinear equations such as the Burgers and the Kortweg-deVries equation. The method of reduction is based on a singular perturbation expansion. Applications to the hydrodynamics and the plasma physics are discussed.
