A common function needed for all the boundary forcing data series is the need to add, edit, view and compare these time series for forcings. Following is a summary of the processes and other time series utilities available utilities in EE10. A list of the forcing data is accessed using a LMC on the External Forcing Data menu shown in Figure 1. The number of series that have been generated is shown in brackets. Some of the items in the menu have unique options which are described in the particular page for that option.
The time series for the external forcing data can be assigned to boundary groups and cells later in the Boundary Condition tab. The display on the right of Figure 1 provides the user with a summary of the current assigned boundary groups and input tables, time series.
...
LMC on any item will display a report about the item selected while RMC displays the options to Add New Data Series and Import Existing EFDC Formatted Series. If data series have already been added, the user can edit it through with Edit Data Series and view a plot through with View Data Series.
- Add New Data Series allow allows the user to create a new data series with user's inputs and options.
- With the Import Existing EFDC Formatted Series option, the user can browse to an existing EFDC data file ( QSER.INP, ASER.INP, PSER.INP,....) and the data file will be imported as a data series.

Add New Data Series
Figure 3 shows the Boundary Data Series general form that is displayed when the user select selects Add New Data Series. Except for Harmonic Tides and Hydraulic Structures, all other sub-tabs use this general form. This form can have more options depend depending on the sub-tab selected.

The user can add and delete series with Add New and Delete. Added series will appear in Select Series, the user can select a series using the drop-down list. The name of a series can be edited in Series Name. Press "Enter" afterward to apply the edit.
View Series 
button will plot the series using EFDC_Explorer plotting tool. The user can choose to plot multiple series and multiple layers in a graph using View Options.
The user can copy the data from data file and paste it directly in to the table as in Figure 4. This table behave behaves like an a Microsoft Excel (c) table where the user can use Shift , and Ctrl keys to select multiple cells and includes options like Copy Data, Paste Data, Insert Row, Delete Row (Row buttons as highlighted in Figure 4 ) .

An alternative option is to import an existing ASCII data file and replace the current series data with the new data with the Import Series 
button (Figure 5 )
...
Once the user does this an ASCII Data Import form will appear as shown in Figure 6. The user can choose the data file to import with the Browse button. Various import settings can be adjusted here such as Header Rows to Skip, and Data Base Date,...
The following provides a quick guide to the use of the ASCII data import form:
- Select the data file to import using the Browse button.
- Select the delimiter.
- The Data Column to Import should point to the column number that contains the Y data. If there are more than 2 two columns in the data file, it is advised to select Multiple Columns button and assign which type of data the columns is.
- As changes are made the information in the Data Preview frame provides the results of the current settings.
- Preview/Graph graph the results of the current settings to see if the import results are what was expected. If not, make further adjustments, as needed, until the data import imported plot is correct.
- Press OK to finalize the actual importing process.
