== Why does hazard output (Z1, Z2, ...) show float values and not just integers? ==
The hazard values are calculated in cell corners and are in a form of an integer. When the values are processed into a grid, which has, by default, a resolution of half the cell size, the values are interpolated to the cell centres - four cell centre values per cell. Further interpolation occurs when the model has a non-zero orientation
== Why are results from 2d_po features, POMM.csv and plots extracted from XMDF in GIS package not matching? ==

==How to create a maximum grid for datasets without direct maximum output from a TUFLOW run?==
For cumulative datasets without direct maximum output (e.g.
For non-cumulative datasets without direct maximum output (e.g., Froude number, rainfall rate etc):
Line 74:
*Confirm the dataset's output ID number in the resulting (maxmax).xmdf file:
<pre>"C:\TUFLOW\Releases\res_to_res\res_to_res_w64.exe" -xnfo (maxmax).xmdf</pre>
*Convert the resulting dataset to a preferred grid format for GIS
:Note: For non-cumulative datasets, this method does not capture the true maximum, however can be close enough with a fine map output interval.

== Why are the values of the mapped water level results (h_max) lower than the terrain elevations (DEM_Z)? ==
As
In TUFLOW HPC, the cell averaged depth is used computationally and by default in the depth outputs (see below).
