A new Pipe Junction Water Quality category was added. In the Propagate Salt method, the Pipe Junction methods behave like the confluence object in that it sums salt mass: Flow 1 Salt Mass + Flow 2 Salt Mass = Flow 3 Salt Mass. Salt concentrations are a flow weighted average. For more information, see Propagate Salt in Water Quality.

On the Water User, two methods were implemented for the new Salt Storage category:

These methods model the diversion and return flow salt mass and concentration including the storage of salt mass in the soil moisture volume. They are the same except the latter also computes supplemental flow salt and adds it into the salt mass balance.
