As atof TUFLOW Buildversion 252025.1.1, there is a current limitation foraffecting result outputs atfor shallow sheet flow cells on steeper terrain in sub-grid-scale sampling (SGS) enabled models. Direct rainfall models are particularly prone to result inproducing substantial extentsareas of shallow sheet flow.
 
In TUFLOW HPC, the cell averaged depth is used computationally and by default in the depth outputs (see below).
