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 ... may be downloaded to aid the user in following along with this guide (a temperature series is not included in the example model at this stage).
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).
...
Goal
Determine regions of the model domain which satisfy a specific range of depth and temperature characteristics over a defined time block.

The HabitatRiver model is provided available on EEMS website and can be downloaded freelyto run in the free Demo version of EEMS. The HabitatRiver model will be used to demonstrate the application of these the thermal and depth criteria 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 Adultcod-like burbot fish species (Lola lota).
Burbot Adult burbot typically occupy areas which have a minimum depth greater than 1.00 m (3.28 ft) and preferred summer temperatures temperature range of 10-12 oC.

Step 3: Enter Critical Habitat Limits and Display
With the information provided in Figure 2 and in the Model Description above, 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.
