This How-To guide is intended to guide users in the application of the Thermal and Depth Criteria Limits analysis features of EFDC_Explorer. A demonstration model has been provided ... to aid the user in following along with this guide.
Any model which uses the temperature module can utilize the Thermal and Depth Criteria Limits analysis features. This type of analysis is generally applied for species whose habitat requires a specific range of water depths and temperatures over a defined block of time (for example 2 days).
Goals
- Determine regions of the model domain which satisfy a specific range of depth and temperature characteristics over a defined time block.
Model Description
The HabitatRiver model is provided on EEMS website and can be downloaded freely. The model will be used to demonstrate the application of these features. The model is configured to simulate temperature effects in addition to hydrodynamics. The focus of this model is to identify suitable habitat for the Burbot Adult.
Burbot Adult typically occupy areas which have a minimum depth greater than 1.00 m (3.28 ft) and preferred summer temperatures range of 10-12 oC.
Step-by-Step Guide
Step 1: Run the Model
Model outputs are required to complete the Thermal and Depth Criteria Limits analysis. Press the Run EFDC button on the main form of EFDC_Explorer.
Step 2: Open the ViewPlan and Habitat Analysis Tools
From the main form of EFDC_Explorer, open the ViewPlan window and use the keyboard shortcut Alt+H to access the Habitat Analysis Tools (Figure 1).
Figure 1. ViewPlan window, with the Habitat Analysis Tools shown (keyboard shortcut Alt+H).
Enter "1" into the text box and press OK to open the Thermal and Depth Criteria Limits dialog (Figure 2).

Step 3: Enter Critical Habitat Limits and Display
With the information provided in Figure 2 and in the Model Description, populate the Critical Habitat Analysis form that now appears in the ViewPlan window. Once the form is populated, press the Display button to show cells which meet the defined criteria. You can change model snapshots to advance or go back in time by using the Page Up and Page Down buttons on your keyboard, or using the Timing slider on the right side of the ViewPlan form.
