WMS:HSPF Mass Links
The Mass Link Editor is a dialog box that is used to create links between two hydrologic units of the topologic tree and set up the MASS-LINK block of an HSPF run. Information the MASS-LINK block may be found in Section 4.6.4.2 of the HSPF manual[1]. In WMS, a list of mass links may be created for each segment type: PERLND, IMPLND, and RCHRES. The mass links for each segment type will be applied to all segments of that type in the model.
The Mass Link Editor dialog allows the user to add or delete mass links for each type of segment. To open the dialog, select Mass Link Editor from the HSPF menu in the Hydrologic Modeling module. To add, just select the segment type from the box in the upper left of the dialog, select the appropriate options in the various combo boxes, input a value as the conversion factor, then hit the Add Link button. To delete, select the line in the text window to be deleted and click the Delete Link button.
If a number of mass links are to be used for many simulations, it would be wise to save the mass links to a file that would be read in any time they are needed. The Export button allows the user to specify a filename and then the mass links are saved as an UCI-formatted ASCII text file. The Import button allows the user to read in a previously saved mass link file.
