To produce a suitable rainfall event from a total depth and duration it is necessary to add a shape, or profile, to a storm which is characteristic of the geographical location. These shapes are usually expressed as a Temporal Pattern. If you combine an average intensity read from the User Defined table with a Temporal Pattern, the result is a rainfall profile (hyetograph) which shows the variation of rainfall throughout the whole storm. This can then be used by the analysis to produce a result for the given system.

**New - **Allows a new Temporal Pattern to be created.

**Load - **Allows an Temporal Pattern to be loaded from file. These include:

> Macro (legacy-content)

**Save - **Save the current Temporal Pattern to a .idtpx file so it can be reused elsewhere.

**Label - **This is the name given to the temporal pattern.

**Profile Type - **The information can be entered in a variety of different profiles types. These are:

- Custom Minute - Allows the information to be entered in non uniform time intervals. Note: The length entered will dictate the storm duration that can be created.
- Custom Dimensionless - Allows the information to be entered in non uniform percentage intervals. Note: ANY storm duration can be created with this format.
- 24 Hour storm - 10 Minute interval - Allows the information to be entered to describe a 24 hour storm at a 10 minute interval. Note: The storm duration that can be created will be limited to 24 hours.
- 24 Hour storm - 15 Minute interval - Allows the information to be entered to describe a 24 hour storm at a 15 minute interval. Note: The storm duration that can be created will be limited to 24 hours.
- 24 Hour storm - 30 Minute interval - Allows the information to be entered to describe a 24 hour storm at a 30 minute interval. Note: The storm duration that can be created will be limited to 24 hours.
- 48 Hour storm - 30 Minute interval - Allows the information to be entered to describe a 48 hour storm at a 30 minute interval. Note: The storm duration that can be created will be limited to 48 hours.
- 7 Day storm - 1 Hour interval - Allows the information to be entered to describe a 7 day storm at a 1 hour interval. Note: The storm duration that can be created will be limited to 7 days.
- Dimensionless - 1% interval - Allows the information to be entered at a 1% interval. Note: ANY storm duration can be created with this format.
- Dimensionless - 2% interval - Allows the information to be entered at a 2% interval. Note: ANY storm duration can be created with this format.

**Editable Column - **Select whether to use Absolute or Cumulative values. 

**Value Options - **The Temporal Pattern can be entered as three different values: Rainfall percentage, Rainfall Depth or Rainfall Intensity. Select the option that is appropriate for the data to be entered.

- **Rain (%) -** The percent of rainfall that falls for the given storm duration.
- **Rainfall Depth - **The depth of rainfall that falls for the given storm duration.
- **Rainfall Intensity - **The average intensity for the rainfall that falls for the given storm duration.

### Spreadsheet
