There are two ways to import models and their alternatives into a watershed: (1) the import CWMS 2.1 Watershed command found in the Watershed menu, or (2) choose commands from the Import menu option (Figure 1) found in the Models menu.

To use the import CWMS 2.1 Watershed command, a CWMS watershed configured in Version 2.1 or greater can be used. The individual model import commands do not require a configured CWMS watershed.

Importing an Entire CWMS Watershed

There are two ways to import an entire watershed. The first way uses the Create New Watershed dialog by completing the following steps: 

  1. Create a New Watershed as detailed in Creating a Watershed.
  2. On the Create New Watershed dialog, navigate to the Import CWMS 2.1 Watershed option.
  3. Click the Browse button to the right of the Import CWMS 2.1 Watershed option to open the Select Workspace File browser dialog. 
  4. In the file browser dialog, navigate to and select the CWMS 2.1 workspace file (.wksp) you want to import.
  5. Click Open, and the Select Workspace File dialog closes.
  6. In the Create New Watershed dialog click OK, and CWMS imports the selected CWMS 2.1 watershed in to the current CWMS watershed. The results of the import are displayed in the Import CWMS 2.1 Watershed dialog ( Figure 2).

  7. Click Close, the Import CWMS 2.1 Watershed dialog will close.

Importing Model Alternatives

Individual models and their associated model alternatives can be imported into a CWMS watershed. A model can be imported regardless of whether the model is part of CWMS watershed or exists as a stand-alone model.

To create a new watershed from scratch, complete the following steps: 

  1. Create a new watershed as detailed in Creating a Watershed.
  2. Import an MFP alternative as detailed in MFP Model Alternative.
  3. Import an HEC-HMS alternative as detailed in Create a HEC-HMS Alternative.
  4. Import a HEC-ResSim watershed as detailed in Create a HEC-ResSim Alternative.
  5. Import a HEC-RAS alternative as detailed in Create a HEC-RAS Alternative.
  6. Import an HEC-FIA alternative as detailed in Create a HEC-FIA Alternative.
  7. Create and configure other model alternatives as desired. Model alternative creation and configuration are detailed below.
  8. Save the watershed.
