Regionalization allows the elements of InfoDrainage to be reordered or removed in order to keep the workspace uncluttered, and provide quick easy access to various functionality.

Region Detection

Upon first opening InfoDrainage, the region will be set by determining your PCs format region, in the same manner that the language translation and units are configured. If InfoDrainage could not recognize the format as being specific to a region, then the Global region must be selected.

The region can be changed using Preferences. InfoDrainage will then remember the set region, and will then open in that region rather than using your PCs format region.

Region Validation

The following actions can create a scenario where an attempt to load values restricted for a region is made:

• Loading new files, including presets and rainfall.
• Changing the region with files already loaded.
• Performing an undo/redo with the region being changed in between.

If one of these actions does result in attempting to load values restricted to the region, the following warning message will appear:

This warning provides a brief description of the issue, including the current region, followed by a table that enumerates all issues. The following columns are shown in the error form:

• Data - The area / file where the issue occurred. This will be either Presets, Rainfall, or Site.
• Properties - The property in the data that has caused the issue.
• Values - The specific value used by the property that has caused the issue.

If you click OK, the warning message will set the region to global. If you click Cancel, the action will be terminated. The undo/redo does not allow the option to cancel.

What is Regionalized?

The following tables display the values that are available in InfoDrainage for the given property, in the order they appear.

Autosizing

Layout (Network Design Report)

Method (Network Design Criteria)

Optimize Velocity (Network Design Criteria)

Default Preset Values

The values of properties associated with default presets (the items available in the toolbox) can be varied across regions. The default values are used in the global region. All properties that differ in any region are listed in the following table:

Inlets

All inlets are available for all regions, except HEC-22 inlets, which are not available in the United Kingdom region.

Preliminary Sizing Calculators

The following values are available for the Preliminary Sizing Calculators.

Rainfall

Regionalization only applies to design rainfall. Other forms of rainfall (IDF, Table IDF, and Known Rainfall) are available to all regions.

Runoff Methods

The following methods are available for Inflows.

Analysis

The Static runoff method in Analysis Criteria is only available in the following regions:

• Global
• France
• United States

The Safety Factor for analysis is only available in the UK and Global regions. Default values are as follows:

• UK -  2.0 (required)
