Permission | Submission moderator and higher |
Connectivity | Online and offline |
This document describes the functionality of the 'hazard assessment' workflow module and how to properly configure it for a workflow.
Required permissions:
- You need to be a Operation administrator to create a workflow template.
- You need to be a Submission moderator to initiate a workflow instance.
Required connectivity:
- You need to be online to create a new or edit an existing workflow template.
- If you are online when you initiate a workflow instance the fields will be prefilled from the last workflow instance with the same location(s). Once the workflow instance has been loaded, you can complete the workflow in an offline mode.
- You can initiate a workflow instance when you are offline, and the fields will be filled with the latest cached information on the computer. This will be up to date unless workflows have been submitted using other computers since you were last online on the computer you are currently using.
- If you submit whilst offline the workflow will be uploaded to the InfoEx server the next time you are online. WARNING: If the internet connection is lost whilst this is being done, the workflow may not be submitted and you may lose the data.
Functionality
The hazard assessment workflow module allows users to assess avalanche hazard according to the conceptual model of avalanche hazard developed by Grant Statham and his colleagues. The hazard assessment process consists of two steps:
- Identifying the present avalanche problems and characterizing their condition using a hazard chart
- Assessing the overall hazard given the existing avalanche problems
If you are not interested in the highly structured approach of the conceptual model of avalanche hazard, the Hazard comment module offers a low-tech alternative that allows you to enter a free-form description of the current avalanche problems and the resulting avalanche hazard.
The data entry fields of this workflow module are automatically pre-populated with the last Avalanche Problems and Hazard Ratings that were submitted for the location(s) associated with the workflow.
NOTE | If you have multiple workflows for a location (e.g., AM and PM meetings), the information is pre-populated from the last time you submitted any workflow for the location. For example, in a regular rotation, the hazard assessment step in the PM meeting is pre-populated with information from the AM meeting and the next AM meeting is pre-populated with information from the PM meeting of the previous day. |
Any workflow template with a hazard assessment module step will automatically have a Workflow summary step added at the end of the workflow. This summary allows users to review their observations and assessments before they are submitted.
The assessments submitted via the hazard assessment module are associated with the location(s) specified for the workflow in 'Manage Workflow Definitions' (or the location(s) associated with this hazard assessment module step if you have more than one hazard assessment module in the workflow).
It is possible to complete the hazard assessment step in a workflow without internet connectivity.
Layout
The hazard assessment workflow module consists of two steps:
Step 1: Avalanche problems (Fig. 1)
The first step of the hazard assessment module allows you to identify and characterize the current avalanche problems according the the Conceptual model of avalanche hazard developed by Grant Statham and his colleagues.

Step 2: Avalanche hazard (Fig. 3)
Having identified and characterized the current avalanche problems, the second step of the hazard assessment process allows you to discuss and rate the overall hazard. Depending on your settings, you will be presented with one general or three elevation-specific hazard charts (Fig. 3).

3. | Depending on your settings, specify the following ratings:

4. | Indicate the forecasters' degree of confidence in any of the included ratings using the scale of Low, Moderate or High. Factors affecting the confidence can include anomalies, unusual events, unprecedented events or conditions, amount of available data, quality of available data, spatial scale, temporal scale, spatial variability, temporal variability, lingering instability, state of knowledge, and forecasters’ experience.
| ||
5. | If necessary add informative comments to describe the particularities of the current hazard situation. | ||
6. | Click on the → button to move to the next step in your workflow. |
Settings
The hazard assessment workflow module has the following settings (Fig. 4):
- Name
Name of the workflow step shown in the header of the workflow. It is recommended that you choose a short name (e.g., 'Av Hzd' instead of 'Avalanche Hazard') to keep the navigation bar of the workflow as tidy as possible.
- Enable Distribution List?
Select this checkbox on and add email addresses to create a special distribution list for this workflow module only.
- Elevation Bands
Specify whether you want to rate the conditions for each elevation band (alpine, treeline, below treeline) individually or just a single, general rating. With the three elevation band setting you will be presented with three hazard charts in the second step of the assessment process (one for each elevation band); with the general setting only a single general hazard chart.
- Hazard
Specify whether you want to include hazard ratings or no ratings at all in your assessment process.
- Private assessment?
Select this checkbox on if you do not wish this module's submitted information to automatically appear in reports. Private assessments and earlier in day assessments can be viewed by checking on the "Include Proprietary Data?" checkbox in reports.
- Locations for Assessment?
Leave this blank if the Locations for Workflow should be used for this module. Add location(s) if you want different location(s) to be associated with this module. If you have more than one hazard assessment module in a workflow they must be for different locations.
All of the information entered in this workflow module is shared within the InfoEx in the following manner:
- The characterizations of the existing avalanche problems are presented in the 'Avalanche Problems' and 'Avalanche Hazard' tables of reports.
- The hazard assessments are presented in the 'Avalanche Hazard' table of reports.
- The assessments are presented for the location(s) that were associated with the workflow.
- For a given day, reports only show the latest assessments submitted for a workflow location. For example, if you include the hazard assessment module both in your AM and PM workflows, reports will only show one of these assessments. Depending on the time of the day, it will be either the AM or PM assessments. Use the "Include Proprietary Data?" checkbox to view all modules for a day.
