Menu:  Run Load Response

This procedure evaluates water quality response in any segment to varying phosphorus loads from any tributary.    It can be used to estimate target loads consistent with achieving a specific water quality objective.  

The user defines the following:

• Tributary to be tested ( "all" = vary total load from all tributaries (sum of monitored inflow, nonpoint, & point-source loads)
• Segment to be tested (or area-weighted-mean)
• Output variable to be plotted
• Method:   (1) Vary tribuary Total P & Ortho P concentrations  (flows constant) or (2) Vary tributary flows (concentrations constant)
• Scale Factor Range:  Low (default = 0.2) ,  High (default = 2.0);  Loads varied from 0.2 to 2.0 times the current load
• The x-axis on the chart is the P load from the tested tributary
• An error message will appear if the selected tributary is not an external inflow (monitored, non-point, or point-source).
