Now that you have created forecast runs, created a forecast, and have reviewed the data for a forecast, you need to link the model alternatives that are part of the forecast runs that are associated with the forecast. From the HEC-RTS main window, click the Modeling tab, from the Forecast menu, click Model Linking. The Model Linking Editor will open (Figure 1), for each defined forecast run, you will be linking each model alternative. For example, you will want to use output from your HEC-HMS and HEC-ResSim models alternatives as input to your HEC-RAS model alternative. Model Linking Editor provides further details on model linking.
