Time Patterns Command

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

Follow the steps below to define time pattern data using the Time Patterns command:

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

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

Selecting Time Pattern

The Select Time Pattern section allows the user to select the time pattern for which time pattern data will be defined. In this section, the user can create, delete, and copy existing time pattern data to a new time pattern. In addition, the user can navigate between time patterns and enter a description for each time pattern.

The following options are provided in this section:

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

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

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

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

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

Time Pattern Specifications

This section allows the user to define the time pattern data and view a time pattern summary for the defined time pattern.

Time Pattern Data

This subsection allows the user to define the time pattern data of the dry weather flow (typically sanitary flow) based on the defined time pattern type and unit multiplier value. The user can select a time pattern type from the Time pattern type dropdown combo box. The following entries are available:

• Daily: One multiplier for each day of the week.
• Hourly: One multiplier for each hour from 12 midnight to 11 PM.
• Monthly: One multiplier for each month of the year.
• Weekend: Hourly multipliers for weekend days.

This subsection contains a table whose first column changes to time, days of the week, and months of the year based on the selected time pattern type. The second table column allows the user to enter the unit multiplier values corresponding to the fields of the first table column.

Time Pattern Summary

This subsection displays the summarized data defined for the current time pattern.

The following options are provided in this subsection:

• Minimum unit multiplier
  This read-only field displays the minimum unit multiplier value defined for the current time pattern.

• Maximum unit multiplier
  This read-only field displays the maximum unit multiplier value defined for the current time pattern.

• Unit multiplier total
  This read-only field displays the total of all the unit multipliers for the current time pattern.

• Unit multiplier average
  This read-only field displays the average of all the unit multipliers for the current time pattern. Generally, this average value should be near 1.

Importing Time Pattern Data

The [Import Pattern] button is used to import the time pattern data from an external text file.

Click the [Import Pattern] button and the Import Time Pattern dialog box will be displayed. Select the text file and click the [Open] button to import the time pattern data.

Exporting Time Pattern Data

The [Export Pattern] button is used to export the time pattern data to an external text file.

Click the [Export Pattern] button and the Export Time Pattern dialog box will be displayed. Browse to the directory location, enter the file name, and click the [Save] button to export the time pattern data.

Time Pattern Plot

This section contains a graphical plot that displays the time pattern type versus the unit multiplier plot for the defined time pattern data. If the Unit Multiplier values are set to zero for the selected time pattern type, the plot will be displayed blank.
