(EAASR), a CERP reservoir. The selection of comparable systems is also documented in
Reisinger et al (2006).
Long-term average evaluation of comparable systems
Walker and Kadlec (2005a) tabulated the long term averages of a comprehensive
set of 18 comparable Florida lakes and a reservoir in the documentation of the DMSTA
v.2 calibration (Figure 4-6). The long term average values were used to determine
several closely comparable systems of the Single Compartment base EAASR Scenario.
The SC base scenario was used, because it is the most general of the scenarios. The
analysis was performed on both the water quantity and TP water quality of the
comparable dataset, as they were inseparable for parameter estimation. The analysis of
comparable was performed using three categories of decision variables: lake
characterization, water quantity, and water quality. The decision variables and weighting
factors were chosen to best represent the parameters in Equation 3-4. The selected
decision variables for lake characterization are surface area and depth. Water quantity
was represented by the HRT and HLR. Water quality was represented by the inflow TP
concentration. A weighted decision matrix was used to evaluate the dataset of
comparable. A rating of one to five was given for each decision variable for each lake,
where five was the most comparable to the EAASR. A weighting factor was applied to
each decision variable, where the sum of all weighting factors equals one. The percent of
the total points (five) was used to rate each dataset. Equation 4-6 was used to calculate
the rating of each lake or reservoir.
