The WQ Reservoir Routing category is used to specify how salinity routes through a reservoir. It is available for Well Mixed Salt. Two methods exist, the default Predictor-Corrector Salt and the Weighting Factors Salt method. The method currently in RiverWare uses a weighting factor to release salt over multiple time steps in a manner that prevents numerical instability, which occurs when reservoir storage is small in relation to the salt routed through the reservoir over a single time step

The Predictor-Corrector Salt method uses a Huen numerical method to compute reservoir salinity concentration that treats reservoirs as “true” fully mixed systems. This method requires that the reservoir salinity and reservoir outflow salinity are the same for a given timestep.

This method is used to limit the available dispatch methods. When this method is selected, the available dispatch methods are:

The Weighting Factor Salt method uses a weighting factor to release salt over multiple time steps in a manner that prevents numerical instability, which occurs when reservoir storage is small in relation to the salt routed through the reservoir over a single time step.

This method is used to limit the available dispatch methods. When this method is selected, the available dispatch methods are as follows:
