Within FEWS-software a certain terminology is used to clarify the relation between scenarios, workflows, runs etc.
relational picture needed
whatif-scenario
Within the NGMS-software, a scenario or what-if scenario basically refers to the specification of the adjustment (if any) of the model data.
Runs
Within NGMS, a run (alias task run or forecast) refers to the output of a workflow (i.e. set of data processing activities), given a specific initial state (starting condition) and a scenario (to modify the input if needed).
Workflows
A workflow is the set of activities related to the pre-processing, running and post-processing of a model.
Within NGMS, various workflows are distinguished as not all runs require that all activities are executed.
E.g. a default run, such as the Calibrated Historic, or Naturalized run, just involves the execution of Modflow, with a set of input files, and the associated post-processing.
However, to run a modified scenario, some additional pre-processing activities are needed - to modify the Modflow input files - before the Modflow executable can be started.
The combination of data processing steps associated to a run, i.e. preprocessing, model execution, and postprocessing, is called a workflow. A run is identified by its workflow as well its scenario
Within the NGMS the following workflows are identified:
- _import
- _default_scenarios
- _ref(Naturalized)
- _ref(Historic)
- _ref(RecentActual)
- _ref(FullyLicenced)
