The linking for an MFP model alternative defaults to the HEC-RTS watershed's extract list (see HEC-RTS User's Manual for further information). HEC-RTS will ask MFP what data (DSS pathname) is needed. MFP will provide the available cases, and HEC-RTS assumes it will be extracted from the observed dataset (database). The dates in the pathname will be changed when a forecast is run. Click Apply (Figure 7.5) to save the model linking for the MFP model alternative.
