IN THIS ARTICLE
Select and enable models to estimate the environmental benefits of your planned implementation activity. This article walks through the components to calculate environmental benefits.
Models
Models are associated with individual activities. Most models require a combination of inputs collected during the activity set-up process (activity type and location via geometry) and unit inputs for the extent. Some models require additional inputs in order to generate outputs.

Generate outcomes using models
The models page changes depending on the activity type that you selected. Let's tour a common view of this page.
Step-by-step tour
The model view changes depending on the activity type selected and the model selected. This tour displays a basic Adapted CAST activity type, Bioretention/rain gardens - A/B soils, no underdrain
.
Select the model that you want to use from the drop down.
The Best Management practice code is based on the selected
Activity_type
and is uneditable from the model view.The Land river segment(s) is based on the delineated geometry and is uneditable from the model view.
Unit type is populated from the efficienty tables associated with the Adapted CAST model. This is not an editable field. All CAST BMPs have a single selectable unit type.
Enter the Unit value.
Click Save inputs.
Model Tips
If you last ran the model prior to 2024, we recommend using the clear button to refresh the page and re-calculate the outputs.
The Adapted CAST model does not include efficiencies for every combination of land-river segment and activity type. If the efficiency tables used to calculate load reductions do not contain values for your selected land-river segment, the model view will display a message indicating this. In such cases, you will not be able to generate load reduction estimates based on your inputs.
