The actual performance of the EAASR/STA system could vary widely from the

predictions presented in this thesis for several reasons including:

* Inflow quantities and water quality can be expected to vary over the next 50 years

* The SFWMM estimates of inflows and operations are not based on any kind of
 optimization for the EAASR/STA system but represent an estimate of their role in a
 regional water management scenario.

* The behavior and performance of the EAASR/STA can be expected to vary
 depending on how it is operated for flood control and water supply purposes as
 well as water quality enhancement.

 Steady state modeling of long-term average outflow concentrations was

performed to provide key insights on the compartmentalization and general operations of

the EAASR and STA 3/4. Further work is needed to assess the operations EAASR and

STA 3/4 in more detail. The results of this study should be calibrated against daily time

step simulations of the operation of the system. The daily simulation should be guided by

an optimizer that directs the simulator towards optimal operating policies. This

simulation/optimization strategy needs to incorporate a life cycle analysis and the

existing as well as proposed constraints on multi-purpose operation that are embedded in

the SFWMM. The life cycle evaluations of the performance of the EAASR/STA system

should include explicit consideration of the need for periodic maintenance and removal of

settled materials.
