Parflow versus WRF-Hydro #2

Produce a write-up that is intended for an incoming graduate student. For each of Parflow, WRF-Hydro (national water model is a configuration of WRF-Hydro)

who originated the model?
what is it used for?
- Is this an operational model?
- Is this a research model? (what do those two terms mean and why is the distinction important?) From the CS side the two probably look similar. Operational models are more "battle tested"
what are the "core equation" being solved for each?

Practical considerations:

where does on find them?
How are they installed?
How do you run each of them?

I am confused about the terminology here: "For each of Parflow, WRF-Hydro..." My understanding is that these are both software tools, but the task makes them each sound like they're "models" unto themselves. Logically, I am assuming this task is to identify the difference between the NWM (created using WRF-Hydro) and CONUS 1.0 (created using Parflow), but I am not certain.

@cathieO @LejoFlores could I get your input/clarifying remarks?

In this context the "model" is either WRF-Hydro or ParFlow, but there is a whole tool stack that is still required to do preprocessing, potentially manage runs in an HPC environment (i.e., Matt's scripts), and or post-processing that needs to be done.

I guess the convention, although there's no rigorous definition, is that an operational model is more "battle hardened" against potential faults and has a more clearly identified update/refresh cycle and fewer active developers.
