WMS:Saving and Reading MODRAT Files

While working on the definition of MODRAT parameters, or when finished, you will want to save the data. There are 2 options for saving a MODRAT model:

1. Save a WMS project file - this will save any data in WMS (DEMs, soil layers, watershed delineation, etc.) as well as the MODRAT data assigned to each basin, outlet, or diversion of the watershed model. This is the option that is most useful as you are working to build a model and want to return to edit it later. To read this file back into WMS at a later time, just use the Open command from the File menu.
2. Save only the MODRAT standard input files - the Save MODRAT File command in the MODRAT menu saves all MODRAT input data to standard MODRAT input files. The format of these file is consistent with that defined in the MODRAT users manual. This file may be named anything you choose, typically with the .lac suffix. The rain input file will be saved with the .dat suffix. If there are any reservoirs or input hydrographs defined, these input files will be saved as well. The files saved can be reviewed in the MODRAT Job Control window. Note that the MODRAT input file does not save any geographic data (maps, DEM, tree item locations, etc.)

Once these MODRAT files have been saved, they may be read in later using the Read MODRAT command. Reading this file will build a topological tree and assign the MODRAT parameters to the tree.
