Line 51:
* Use depth varying manning's n (lower manning's n for shallow water depths), specifically for direct rainfall models.
* Set appropriate <font color="blue"><tt>Map Cutoff Depth </tt></font> for the modelling task. e.g. direct rainfall models might have higher values to avoid undesirable noise on the wet/dry interface.<br>
* Use smaller 1D timestep for models with 1D features.
* Try double precision, specifically for models with higher elevation, 1D features and or very small flow/rainfall depth increments.
* When running HPC and or Quadtree, test control number factor smaller than 1.
