Cells appear wet when very small differences of bed levels within computational cell (with subgrid)

[roeldegoede]

When setting up a subgrid model with a resolution that is higher than the resolution of the underlying dataset, all subgrid "pixels" potentially have the same bed levels. If that is the case (this only happens in theoretical (and stupid) models probably), cells turn unexpectedly up "wet".

This was noted after weird patterns were notified in the produced water levels. The regular pattern here is caused by the underlying DEM (Merit Hydro ~90m resolution). Model resolution here was 12.5m, to have an extreme case. All the cells that turn up wet completely fall within one cell of the underlying data.
