Adopting a multiple scale method, the non-linear evolution of fully developed dunes of non-cohesive sand is studied using Kennedy's model. It is shown that both the 2 and 3 dimensional problems are, in general, governed by 3 coupled second-order partial differential equations. It is also found that the uniform Stokes 'wave' is a solution of the general problem. The results are in broad agreement with the cumulative effects of dune movement over long periods. -from Authors
