I'm sure this has been asked before, but I'm trying to clarify my understanding of the inputs for runoff quality.

All questions assume one landuse per subcatchment.

If I have one landuse, and one constituent, and want to simulate constituent buildup as a fraction of dust and dirt, then do I specify QFACT1=the fraction of the constituent in mg/g?

If I have two landuses, and two constituents, then do I enter a fraction on each constituent line for QFACT1 and QFACT2?

If I have greater than 5 landuses, then assuming my previous two suppositions are correct, then how do I add fractions for landuses > 5?
