A new method was added to the reservoir objects in the Reservoir Water Quality category called Segmented 2 Layer Salt. In this method, the reservoir is discretized into two vertical layers with a constant Thermocline Elevation and a user defined number of longitudinal segments. Inflows and Outflow from each layer are distributed according to user specified proportions. Flow between segments and layers is used to model reservoir salinity.

See WQ_Segmented_2_Layer in Water Quality for details of this method.

A new method was added to the WQ Distribute Outflow fraction, Specify Outflow Fraction. The new method allows the user to specify periodic or series of fractions defining the percentage of Outflow that comes from each layer. For more information, see Specify Outflow Fraction in Water Quality.

In the Specify Fraction method, the Inflow to Hypolimnion Fraction slot was changed from a series slot to a series slot with periodic input. This allows the Inflow to Hypolimnion Fraction to be specified as either a series or a periodic set of data. For more information, see Specify Fraction in Water Quality
