3.5 Using Known Fluxes

For the contaminated aquifer case, the known flux capabilities of the module can be applied to leaching only.  Known flux capabilities can be used in two ways.  The first way to use known fluxes would be to pass known leaching flux rates to the groundwater transport code.  The second way would be to "turn leaching off" by inputting a known leaching flux of 0.  The overall treatment of mass loss in the source-term module does not change.  The known leach rate replaces the calculated value for [dM_i /dt]_leach in Equation 3.4.  All other calculations are done identically to the calculated flux cases.
