TCC Outfall Efficiency Report
Report Description
The TCC Outfall Efficiency Report calculates the percentage of outfall to inflow within a specific channel during the report period. This provides a measure of how efficiently TCC is distributing water to the channel.
Report Parameters and Options
| Parameter | Description |
|---|---|
|
Channel Name |
Name of the channel on which the offtake regulator is located. This field is automatically populated when you select an offtake regulator.
Note that the channel name is stored as an attribute of a regulator. View the regulator properties if you need to find a channel name. |
|
Offtake Regulator |
Offtake regulator that defines the inflow location for the report |
|
Outfall Regulators |
Specify one or more outflow regulators supplied by the offtake regulator. Use the |
|
Start/End Date |
Specify a date range for the report |
|
Outfall/Inflow Threshold |
Specify an acceptable threshold. Only percentage variations for the total outfall that exceed this threshold will be reported. Set this value to zero to show all variations. |
Add and 
Remove tools to manage the list of outfall regulators. Report Output
The output includes the following three tables, and a sign-off performance acceptance form:
Outfall to Inflow Volume
This table shows the ratio of outfall to inflow for the reporting period for each outfall regulator individually and as a total.
| Property | Description |
|---|---|
|
Channel Name |
Channel where the offtake regulator is located |
|
Offtake Site |
Offtake regulator selected for this report. This is the inflow source location for the report |
|
Volume |
Total volume through the offtake regulator during the reporting period |
|
Outfall Site |
One or more outfall sites downstream of the offtake regulator.
A warning message will be displayed if the offtake regulators were not in Upstream Level control mode throughout the reporting period. An offtake in Upstream Level control mode will automatically pass any excess volume downstream to maintain the upstream level setpoint. |
|
Volume |
Volume that flowed through each of the outfall regulators during the report period |
|
Percent Outfall to Inflow |
Outfall volume as a percentage of the inflow volume at the channel offtake. |
Regulators Taken Out of TCC
This table notes any periods during which any of the regulators on the channel were taken out of TCC mode. This may include regulators other than the offtake and outflow regulators.
