    Hello, My understanding is that the water yield model portion of the
   water purification model uses the same framework as the hydropower
   model. This includes incorporating the "Zhang constant" describing the
   seasonal distribution of expected rainfall. The model does not,
   however, ask for an input value for this constant. Is there a default
   value being applied in InVEST for "Z"? Any help is appreciated! Thanks
   very much! Maura
