From the Model Linking Editor, from the Model to Link list select HMS-(RUN)FEB_1986. The Model Linking Editor table updates to contain all of the locations for the HMS model alternative.
Since HEC-HMS wants precipitation and flow data that is not provided by another software application, HEC-WAT reads the linking from the HMS model alternative and displays that linking in the Model Linking Editor table.
The table displays the linking from a DSS file for the HMS model alternative which is the correct linking.
