Data that resides in the watershed's main folder is called base data. Base data includes all the data that supplies information displayed in the Setup, Acquisition, and Visualization modules. This data encompasses all data needed to create a forecast. Base data includes maps, layers, layouts, reports, scripts, extract post information, all model alternatives, shared and study information, and HEC-RTS data. Base data does not include data for the forecast, more detailed information on forecast data is described in Team Forecasting.

This section walks through how to determine which local base data files are up-to-date, how to download base data from the master watershed, and how to upload revised files back to the master watershed to share with other team members working on the watershed.

Master Watershed Synchronization Dialog

The Master Watershed Synchronization dialog (Figure 1) is used to upload or download base data to and from the master watershed. From the HEC-RTS main window, click on the Setup tab, from the Watershed menu, point to Team, click Sync with Master Watershed, the Master Watershed Synchronization dialog will open (Figure 1).

On the Master Watershed Synchronization dialog (Figure 1), the base data is displayed in an expandable tree called the Synchronization Tree. Each node in the Synchronization Tree represents a data group for the watershed. The data groups reflect the folder structure of the current watershed folder (Figure 2).

The Watershed Data node (Figure 3), is a special data group. This data group represents three folders in the watershed's folder structure - study, reports, and layouts. Hovering the mouse over a node in the Synchronization Tree displays a tooltip (Figure 3), that provides information on what watershed folder(s) represent the data group; what master watershed folder(s) represent the data group; what the version is for the local copy of the watershed; what the version is for the server copy of the watershed; and comments.

For example, in Figure 4, the top node is R462 (3/3). This is the name of the watershed. The top node represents all the data groups under the watershed's main folder. If you upload or download this node, all watershed base data will be transferred.

Next to a data group node, there are two numbers shown in parenthesis. For example, in Figure 5, from the Synchronization Tree, the Shared folder has (1/2) displayed. These numbers indicate what version of the folder is on your computer and what version is on the master watershed. The first number (top) represents the watershed that is on your computer. The second number (bottom) represents the version of the master watershed. If the top number is less than the bottom number, the master watershed folder has been updated and the changes need to be downloaded to your local copy. For example, Shared (1/2), informs you that the Shared folder on the local copy of the watershed is Version 1, and the master watershed is Version 2. If the numbers were "(0/0)" or "(Na/Na)", this means the folder has never been uploaded to the master watershed.

In addition to the displayed version numbers, the Synchronization Tree nodes will highlight in different colors depending on the node's revision state (Figure 5). The different colors and their meaning are listed in the Legend area (Figure 5) below the Synchronization Tree. The highlight colors represent the following information:

To upload the files, select a highlighted node (yellow), the Master Watershed Synchronization dialog (Figure 6) now displays an Actions box, from that box, click Upload.

In the Team section of the Master Watershed Synchronization dialog (Figure 6), when you select a data group, information about that data is displayed. In addition, the Actions box (Figure 6) provides you with commands that allow you to interact with the selected data group:

Below the Action box (Figure 6) is the revision information for a selected data group:

Downloading Base Data

If base data has been changed for the master watershed or you would like to get the latest version, you can download the data from the Master Watershed Synchronization dialog (Figure 1).

To download base data from the master watershed:

1. First, from the HEC-RTS main window, open the master watershed that is on your computer, click the Setup tab.
2. From the Watershed menu, point to Team, click Sync with Master Watershed. The Master Watershed Synchronization dialog will open (Figure 1).
3. From the Synchronization Tree (Figure 5), select the data group node that you need to download files. Hovering the mouse pointer over the nodes will display information about the data group node that will be downloaded.
4. From the Master Watershed Synchronization dialog (Figure 1), click Download, the Download from Master Watershed window will open (Figure 7).
5. Click Yes, the Download from Master Watershed window will close, and the download process will start.
   
6. During the download process, the Master Watershed Synchronization dialog will disable and display a Downloading indicator (Figure 8).
   
7. A Download tab will display in the Message Pane, providing status updates during the download process.
8. When the download is complete, a notification message will display (Figure 9), and the Master Watershed Synchronization dialog will be active again (Figure 1).
   
9. When you have downloaded all of the files that you need, close the Master Watershed Synchronization dialog (Figure 1).

Uploading Base Data

Changes made to the base data on the local copy of the master watershed can be uploaded to the master watershed's base data and then shared with other team members. If other team members have the same HEC-RTS study open during the upload, the team members will receive real-time notification messages indicating that the master watershed has been updated after the upload is complete.

To upload changes to the master watershed's base data:

1. First, from the HEC-RTS main window, open the master watershed that is on your computer, click the Setup tab.
2. From the Watershed menu, point to Team, click Sync to Master Watershed. The Master Watershed Synchronization dialog will open (Figure 1).
3. From the Synchronization Tree (Figure 5), select the data group node that you need to upload the files for in the master watershed. Hovering the mouse over the data group node will display information about the data group node that will be uploaded. From the Actions box (Figure 10) click Upload.
   
4. The Enter Upload Comments dialog will display. Enter comments about the files that you are uploading. These comments will be seen by other team members as part of the revision.
5. Click OK, the upload process will start. The watershed will close in the HEC-RTS main window and the Master Watershed Synchronization dialog will become inactive and display an Uploading indicator (Figure 11).
6. An Upload tab will display in the Message Pane (Message Pane - Upload Tab), providing status updates during the upload process.
   
7. When the upload is complete, the watershed will reopen in the CWMS CAVI main window and the Master Watershed Synchronization dialog (Figure 11) will be active again. A Real-Time Notification Message will display (like Download Complete - Real-Time Notification Message) indicating what files have been uploaded to the master watershed. Any team members that have the same master watershed open on their desktops will also receive a notification.
8. If you do not have the most recent files, and then try to upload changes, you will get an Out of Date message (Figure 12).
   
9. This is to prevent you from accidentally deleting another team member's changes. Click OK, then download the outdated files. Downloading files is further explained in the section titled Downloading Base Data.

Out of Date with Master Watershed

If new files have been uploaded to the master watershed since you closed the watershed an Out of Date with Master Watershed dialog will display (Figure 13) when you open the watershed, prompting you to update any files that are out of date.

The Out of Date with Master Watershed dialog (Figure 13) consists of the Data Group table and, Update and History buttons. The out-of-date data groups will have a checkmark in the Update column (Figure 13) of the Data Group table by default. To download the latest master watershed version of the data groups, click Update (Figure 13). All the data groups in the Data Group table with checkmarks will be updated. The Out of Date with Master Watershed dialog (Figure 13) and your watershed will close as the files will begin updating.

The columns of the Data Group table (Figure 13) represent the following information:

The highlight colors in the table are defined in the Legend box (Figure 13). The colors indicate the following states:

At the bottom of the Out of Date with Master Watershed dialog (Figure 13) is a History button. The History button is active when a row is selected in the table. Clicking the History button displays the History dialog for the selected row. The History dialog displays a list of detailed information on the versions for the data group. For information on the Revision History dialog, see the section titled Revision History.
