S. Alireza et al., OPTIMAL-CONTROL OF GROUNDWATER QUALITY MANAGEMENT - NONLINEAR-PROGRAMMING APPROACH, Journal of water resources planning and management, 120(6), 1994, pp. 962-982
A management model is developed that uses a nonlinear programming appr
oach to solve the optimal control problem of managing the generation a
nd disposal of agricultural and dairy waste. The permissible controls
are subject to physical, economic, and social constraints. The model u
ses a state response matrix to represent the response of the physical
state of the system, and a policy response matrix that reflects the ef
fect of policy actions such as pumping, recharge, and manure disposal
on the state of the system. Unlike some combined simulation/optimizati
on approaches, this model includes the dynamic response of the system
as an explicit part of the optimization. To evaluate the applicability
of the model to actual policy problems, the model is implemented in t
he Chino ground-water basin, California. Based on the alternative scen
arios analyzed, a manure-treatment and -disposal program coupled with
an artificial-recharge program are proposed. The rate and schedule of
treatment, disposal, and recharge are determined on the basis of the t
ransport capacity of the underlying aquifer and associated costs. The
model may be used for analysis of ground-water quality regulations or
other management options on the physical state and economic parameters
of the system.
