Using Demonstration Models.
Complete sample projects are distributed with CRHM. These may be found in the directory "CRHM_project_examples" located in the same directory as the CHRM executable.
The subdirectories "Bad Lake", "Marmot Creek", "Smith Creek" and "Yukon" contain complete example projects for different Canadian regions. These projects may be executed from CRHM using the File/Open menu or double clicking the project file from Windows Explorer..
Within CRHM examples of models using different combinations of modules can be constructed using the pull down menus in the Build menu screen. To use them use the following steps.
- Run CRHM.
- Goto the Build/Construct screen to select the desired number of HRUs and exit this screen using Build to register the selected number of HRUs..
- In the Build screen select the example model desired from the list.
- In the Observation screen select a suitable observation file. The file "C:\Program Files\CRHM\Examples\Winter1974.obs" can be used for demonstration purposes only.
- Select some variables to display and click on Run to execute..
This is a training exercise. The usual warnings apply, i.e. the selection of modules, parameters and set of observations must be relevant to the physical application to achieve meaningful results.
Notes.
- It is best to select the number of HRUs before selecting a sample model, then the default parameters are optimum. When the number of HRUs is increased after selecting the model, the last HRU parameter value in the earlier project is duplicated for the new HRUs.
- If a project is already loaded when a sample project is selected, the current modules loaded will be replaced by the model selected. The observation files and number of HRUs will not be affected.
- When a sample model is selected,. its description is added to the first line of the prospective project file and also inserted into the TChart title.
- The user must customise all parameters in the model to define their application.
