WMS:HSPF IQUAL

To access the IQUAL Parameters dialog box, press the '$include "global.sbh"button in the Impervious Land Activity dialog box. This dialog box allows the user to specify up to 10 water quality constituents or pollutants in the outflows from an impervious land segment. The IQUAL Parameters dialog box lets the user enter the parameters for the following IQUAL input tables: NQUALS, IQL-AD-FLAGS, QUAL-PROPS, QUAL-INPUT. The following monthly value tables may also be input from this dialog if required: MON-POTFW, MON-ACCUM, and MON-SQOLIM. Some parameters require a single value for the entire simulation and others are allowed to vary monthly, depending on the flags set in the QUAL-PROPS table. For more information on these tables, see Section 4.4(2).7 – IQUAL input of the HSPF manual.

The key to using this dialog is to note that the NQUAL field at the top of the box designates the total number of constituents to be modeled, while the Editing Constituent Number drop-down box indicates the constituent that is available for editing in the fields below.
