| Abstract | The objective pursued in water quality management is to
secure water qualities where the marginal cost of the clean water
equals the accruing marginal benefits. It is the purpose of this
study to show how the methods of system analysis may be used to
plan for new pollution control facilities or to upgrade existing
systems.
Two kinds of water quality management models are formulated
in this study; 1> the optimal treatment cost model and 2ยป the
effluent charge model. The treatment cost model is concerned with
treatment plant as well as pipeline cost. This model is discussed
at three levels, i.e., district, local and stream.
To approach the problems, a stream water quality simulation
model - - QUAL2E was linked with the optimization models to
make use of its unique advantages in managing river basin water
quality. The problems were formulated through two- stage
modelling. In the first stage, the QUAL2E model was applied to
obtain response coefficients and the initial stream water
quality. In the second stage linear and non - linear programming
models with non- linear objective functions and linear
constraints, are used to minimize the total annual cost of
treatment and pipeline and to optimize a water quality management
system by the effluent charge model. |
