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.
Slots Specific to This Method
Max Delta Turbine Release
Type: Scalar
Units: Flow
Description: The maximum Delta Turbine Release throughout the basin and throughout the run.
I/O: Output Only
Links: Not Linkable
Max Delta Spill
Type: Scalar
Units: Flow
Description: The maximum Delta Spill throughout the basin and throughout the run.
I/O: Output Only
Links: Not Linkable
This method is executed at the end of the run. The following computations are made:
(8.1) 
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:
(8.2) 
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 “Total Dissolved Gas Methodology” for details on the Reservoir TDG computations.
