Once you have created forecast alternatives, created a forecast, and have made the forecast active, the Model Schematic Layer will display in the Map Layers editor for the Modeling module. The Model Schematic Layer contains graphic representations of computational models for the active forecast alternative. CWMS Forecasts provides detailed information on forecast alternatives, forecasts, and the different computational models represented in the Model Schematic Layer.
When you expand the tree, you can see the different sub-layers for some of the models that are part of a forecast. For example, if you did not want to see the impacts for the HEC-FIA model, expand Model Schematic. Clear (uncheck) the box next to your HEC-FIA model alternative, and the impact areas defined for the HEC-FIA model will no longer display in the map window. To view the impact areas, check the box next to your HEC-FIA model alternative. This procedure applies to all of the sub-layers.
