SELFE's wetting and drying capability has been carefully benchmarked and verified. There are 2 options: inunfl=0 as a 'light-weight' inundation scheme (you'd always start with this option), and a 'fine-scale' inundation scheme (inunfl=1), which requires some care. In particular, since extrapolation is used with inunfl=1, you'd make sure that the grid is reasonably resolved in the wetting and drying regions. This scheme may also require a smaller time step to very accurately capture the inundation process.

The wetting and drying process is inherently nonlinear and challenging, and here are some tips.
