SummaryA new general method has been obtained to solve the physically-based equations describing the dynamics of sediment adjustment through time following erosion on a plane soil surface. This method is based on exploiting differences in behavior between smaller and larger sediment particles in their ability to form a protective layer by net deposition of previously eroded sediment. The utility of this approximate solution was verified by comparison with a numerical solution, for the particular case when a steady over land flow of water is the cause of the erosion.
► We provide a new approximate analytical solution during non-steady erosions.
► Overland flow is considered as an example.
► Complex physical dynamic processes are considered during the erosion.
► The contribution of both finer and coarser soil particles is explored.
► An interpolation between short and long times is developed.
