After a forecast run has been created you need to link the models, which is accomplished through the Model Linking Editor (Figure 1). From this editor you select a forecast run you wish to configure. Then you select each model alternative that is associated with the selected forecast run. For each model alternative you will determine where you will be getting data from another model alternative. For example, in Figure 1, you specify which model alternative the input comes from and the DSS pathname associated with the model results. For example, you may set the precipitation input data for HEC-HMS to come from an MFP precipitation grid. Refer to Model Linking Editor for additional information on model linking.
