With the What-if functionality in the NWM the user can interactively (via the GUI) change the model data sets, that means testing for example a new schematisation of the model. Within the current version what-if functionality is tested and implemented for the LHM model, hwat is described in the following section.
Use of What-if in LHM
- Place a zip-file with the new data files somewhere at the server: It must be the same machine, where the FSS is hosted which will run the LHM-workflow in combination with what-if. Besides the new model data files also a README.txt or other informative files (e.g. desciption, name date etc) can be stored here. To ensure that these files are also archived the filename extension must be .txt.
- Place a zip file somewhere at your local machine which must be called: lhm_test x.xx.zip. x.xx stands for a unique version number which is set by the user itself . It should just contains one info-file (xx.info) with an absolute path to the in 1. generated .zip-file.
- Upload the lhm_test x.xx.zip (see 2.) from your local machine to the server via the CM (config-manager) of the NWM system. The use of the config manager will be further explained in the next section.
- Go to OC (Operator Client) of the NWM
- Open the What-if scenario display via Menu/Extra/What-If Scenario (or Ctrl + W)
- Make a new scenario (with button Nieuw scenario aanmaken..); if required set a new scenario description
- Specify the scenario with tab 3:Module dataset:
- select from the Module Data Set Bestand combo-box the line lhm_test;
- select the version number from Module Data Set Bestand/Versie combo-box
- confirm with button Toevoegen;
- save it with the button Bewaar alles
- with the button Beheren.. you can delete or modify the scenario
- Start now the LHM run:
- chose the LHM run which includes the base data set
- Specify the What-if scenario (via the Starten Workflow display
