Subbasin Total Dissolved Gas
This category will only be available when water quality is enabled. In this category there will be two methods: None and TDG Max Deltas.
NoneThe None method is the no-action method and is not described further.
TDG Max DeltasThe TDG Max Deltas method computes maximum deltas through the subbasin and throughout the run.

Method Details
This method is executed at the end of the run. The following computations are made.
(7.1) 
Conceptually, this equation says that the Max Delta Spill is the largest absolute value of Delta Spill on any reservoir in the subbasin at any timestep in the run.
Also:
(7.2) 
Similarly, this equation says that the Max Delta Turbine Release is the largest absolute value of Delta Turbine Release on any reservoir in the subbasin at any timestep in the run.
See Outflow TDG using Tailwater Depth for details on the Reservoir TDG computations.
