Clarification Request Regarding Output Water Depth Behavior #197

Description

@samgarofalo

Dear Developers,
I am reaching out regarding a particular behavior I have observed while working with LISFLOOD. When running the model with realistic meteorological input data, outputs such as water depth and surface runoff are only produced for certain grid cells. However, when we use artificially extreme meteorological conditions, these outputs are generated across the entire grid.
My hypothesis is that LISFLOOD may apply some form of thresholding, such that:

  • If the computed water depth or runoff exceeds a certain threshold, the value is retained in the output;
  • Otherwise, the value is discarded or not recorded.

I would appreciate your clarification on whether this behavior is indeed governed by such thresholds, or if it is the result of other internal mechanisms in the model.
Additionally, if these thresholds do exist, I would like to know whether they can be configured via the XML input file, or through any other user-accessible settings.

Thanks in advance.
