This document describes how to create a new [[Definitions#OperationPWL|Operation PWL}} in the InfoEx system.

Background

An Operation PWL is a locally defined persistent weak layer (PWL) in the snowpack. While PWLs in the old InfoEx system were simply referred to by a burial date, the new InfoEx system requires PWLs to be explicitly defined. This allows PWLs to be tracked more easily and offers opportunities for advanced queries.

Operation PWLs are managed within operations. Operation have full control over the characteristics of these PWLs.

An new Operation PWL can be created in two different ways:

• Via the Operation PWL menu item under the PWL heading
• Via the Snowpack workflow module

Step-by-step description

Creating a new Operation PWL via the Operation PWL menu item

1.	Activate the PWL menu from the main infoEx menu.
2.	Fig. 1: Creating an Operation PWL Select 'Operation PWL' beneath 'Pwl' (Fig. 1). The current list of Operation PWLs is displayed.
3.	Fig. 2: Operation PWL settings Select beneath the 'Operation PWL' title. This will open a popup window where you can provide the baseline information for your Operation PWL.
4.	Provide the following information for your Operation PWL (see Fig. 2) Name: Provide a meaningful name for your Operation PWL. Date: Provide the date that your Operation PWL was buried. Comment: Provide a descriptive comment for your Operation PWL, if desired. Community PWL: You may link your Operation PWL to a Community PWL (see: Community PWLs) NOTE Linking your Operation PWL to a Community PWL allows you to retain your local definition and description of the PWL while allowing it to be linked with the same PWL observed in other infoEx operations Colour: Provide a colour that will identify your PWL in hazard assessments.
