Improvements to Source
River Operations Improvements
...
When running Rainfall-runoff models GR4J or Sacramento, you can take a Snapshot of their internal state variables,
This they can then be saved to a file and applied at the start of a model run.
This This removes the need to do a warmup period for running these rainfall-runoff models. The The snapshot files now include catchment name and functional unit names as well as an additional metadata file, e.g:
