For a design with feedback flow sources, the Solver objective and constraint
section is used. Initial estimates of Cin are entered for each feedback. In the Solver
section the difference of the feedback Cin cell and the appropriate compartment Cout cell
are entered. The sum of the square differences are calculated for all feedback flows in
the Total Difference cell and used as the objective in Solver. Each feedback
concentration is constrained to the minimum achievable concentration, C*. Solver is then
used to reduce the value of the objective function to zero, which calculates the correct
concentrations. This methodology assumes full treatment of the feedback flows.
Water Quantity of EAASR and STA 3/4
The purpose of this section is to present the water quantity parameters necessary
for water quality modeling. The reported inflows and outflows to the EAASR and STA
3/4 are based on output from the SFWMM. The water quality performance of the
EAASR and STA 3/4 can be expected to vary depending on how the inflows are divided
among compartments, how the individual compartments are operated as judged by the
mean depth of storage in each compartment, and how water is transferred among
compartments before discharge from the EAASR. Performance will also depend on
whether inflows are routed to STA 3/4 directly or through the EAASR. This section
provides background information and results for the compartmentalization configurations
in Chapter 3.
Water Quantity Data Source and Information
A wide variety of options exist for directing water into the EAASR. The best
projection of the expected inflows can be obtained by using the South Florida Water
Management Model (SFWMM). The Interagency Modeling Center (IMC) modeled the
EAASR and the downstream STA 3/4 using the SFWMM Version 5.4. The IMC
