Parameter Definition Units Instantaneous river water surface elevation measured at the SQN skimmer wall (Station WSEL_SKIM_Inst feet msl 13).

1-hr average hydro river flow at SQN, computed based on 1D unsteady flow model of Q_SQN_Hydro_1-hr Chickamauga Reservoir and hydro releases from Watts Bar Dam and Chickamauga cfs Dam.

24-hr average compliance ambient river temperature measured at TRM 490.4 (Station TUS_COMP_24-hr °F 14).

24-hr average compliance downstream river temperature computed at downstream end TDS_COMP_24-hr °F of diffuser mixing zone by the SQN compliance model.

24-hr average compliance river temperature rise between the measured ambient river TRISE_COMP_24-hr temperature (Station 14) and the computed river temperature at the downstream end of °F the diffuser mixing zone.
