Time Series Command

In GeoSTORM software, the Time Series command allows the user to define time series data for nodal inflow defined at manholes and junctions.

Follow the steps below to define time series data using the Time Series command:

1. From the Input ribbon menu, select the Time Series command.
   
2. The Time Series Data dialog box will be displayed.
   

The following sections describe how to define time series data and interact with the above dialog box.

Selecting Time Series

This section allows the user to select the time series for which data will be defined. Users can create, delete, and copy existing time series data to a new time series. In addition, the user can navigate between different time series and enter a description for each time series.

The following options are provided in this section:

• Time series ID
  This dropdown combo box lists all the time series defined in the current scenario. Click on the edit option (i.e., the pencil icon) to edit the time series ID. The user can navigate between the previous and next time series using the Up and Down arrow buttons.

• Description
  This optional field allows the user to enter additional information that describes the selected time series.

• New
  The [New] button allows the user to create a new time series. The ID of every newly created time series must be unique.

• Copy
  The [Copy] button allows the user to copy the currently selected time series along with its associated data to a new time series. The software automatically provides a unique ID to the copied time series.

• Delete
  The [Delete] button allows the user to delete the currently selected time series from the current scenario.

Time Series Specifications

This section allows the user to define the time series data by either selecting an external data file from the External Data File subsection or manually entering the data under the Time Series Data subsection.

External Data File

This subsection allows the user to select an external data file to define the time series data. The user can click the [Select] button and browse the folder containing the time series data file. The path of the selected file will be displayed in the Data file entry field.

Note that this subsection is disabled (i.e., grayed out) if the radio button in the Time Series Data subsection header is selected.

Time Series Data

This subsection allows the user to manually enter the data to define a new time series.

Note that this subsection is disabled (i.e., grayed out) if the radio button in the External Data File subsection header is selected.

The following parameters are provided in this subsection:

• Time increment
  This dropdown combo box entry lists the time increment that is used to define the time series data. The following options are available:
  

  In minutes	1, 2, 3, 4, 5, 6, 10, 15, 20, 30
  In hours	1, 2, 3, 4, 6, 8, 12
  In days	1

• Time window
  This dropdown combo box entry allows the user to select the type of time window data that is to be entered. The following options are available:

• • From Control Data
  • User Defined

• Select control
  

  This dropdown combo box entry allows the user to select the control data set defined using the Analysis Specifications command. Refer to this article in our knowledge base to learn more about the Analysis Specifications command.

  If only one control data set is defined, then the software will automatically select the control data set. When a control data set is selected, the software will automatically populate the following fields:

  • Start date & Start time
  • End date & End time

Note that this dropdown combo box is only enabled when the From Control Data option is selected in the Time window dropdown combo box entry. Otherwise, this option is disabled.

• Start date/Start time/End date/End time
  

  These fields define the time period for the time series data. From the Time window dropdown combo box entry, if:

  • From Control Data option is selected, then these fields become read-only. The software will automatically fill in the starting and ending dates and times.

Note that the starting and ending dates and times will be populated based on the entries defined in the Simulation Time Window section of the Analysis Specifications dialog box.

• • User Defined option is selected, then these fields allow manual entry of dates and times.

• Time Series Table
  The software automatically fills in the Time column values in the data table based upon the selected Time increment and Start/End dates & times. The user can manually enter the values into the Flow table column.

Time Series Plot

This section contains a graphical plot that displays the Time vs Flow plot for the defined time series data.
