A new method for the treatment of wetting–drying fronts

In this article, a new method is developed for the treatment of wetting–drying fronts in depth-averaged simulations. Some benchmark tests are devised in order to examine the performance of the new method at extreme conditions. The depth-averaged tool with two different wetting–drying process and Fluent6.3 are then applied to the benchmark tests. It is assumed that a solution by Fluent6.3 is the realistic solution and, a depth-averaged solution which is more similar to the solution by Fluent6.3 is more accurate.
