Experiment: study the stability and sensitivity of timestep size

[thurber]

i.e. can one set the timestep to a whole day or a whole month and expect meaningful results?

[thurber]

based on discussions with nathalie, the routing is likely quite scale adaptive but the water management may not be

Triage note (v1.0.0 release review): this is a 2021 research/investigation task (timestep stability and sensitivity) with no owner or follow-up since. Recommend closing or moving to a discussion/backlog unless it's still actively planned.
