A new methodology has been developed for determining the optimal operation of water distribution systems for water quality purposes. The methodology is based upon describing the operation as a discrete time optimal control problem that can be used to determine the optimal operation schedules of the pumps in distribution systems. The solution methodology is based upon a mathematical programming approach resulting in a large scale nonlinear programming problem which can not be solved by using existing nonlinear codes. The solution of the optimization problem is obtained by interfacing a simulation code, EPANET, which solves the hydraulic and water quality constraints with a nonlinear optimization code, GRG2. Bound constraints on the state variables are incorporated into the objective function using the augmented Lagrangian and the bracket penalty methods. Three objective functions can be used in the model: (1) the minimization of the deviations of actual substance concentrations from the desired concentration values, (2) the minimization of the total pump duration times, and (3) the minimization of the total energy cost. The effectiveness of methodology has been tested using both hypothetical and existing water distribution systems.

Optimal operation of water distribution pumps considering water quality
Altan Sakarya, Ayşe Burcu (American Society of Civil Engineers (ASCE), 2000-07-01)
A new methodology has been developed for determining the optimal operation of water distribution system pumps with water quality considerations. The methodology is based upon describing the operation as a discrete time optimal scheduling problem that can be used to determine the optimal operation schedules of the pumps in distribution systems. The solution methodology is based upon a mathematical programming approach resulting in a large-scale nonlinear programming problem that cannot be solved using existi...
New methodologies for optimal operation of water distribution systems for water quality purposes
Altan Sakarya, Ayşe Burcu; Mays, LW (1998-01-01)
Two new methodologies have been developed for determining the optimal operation of water distribution systems for water quality purposes. These methodologies are based upon describing the operation as a discrete time optimal control problem that can be used to determine the optimal operation schedules of the pumps in distribution systems. One solution methodology is based upon a mathematical programming approach and the second methodology is based upon a simulated annealing approach. These two methodologies...
Spatial data analysis for monitoring and prediction of selected water quality parameters in reservoirs: Porsuk Dam reservoir case
Yenilmez, Firdes; Aksoy, Ayşegül; Düzgün, H. Şebnem; Department of Environmental Engineering (2014)
In the design of a water quality monitoring network, selection of water quality sampling locations is crucial to adequately represent the water quality of the water body when high costs of analyses and field work are taken into account. In this study, a new approach was proposed to identify the representative water quality sampling locations in reservoirs and lakes using geostatistical tools for estimation of spatial distribution of selected water quality parameters. To do so, kernel density estimation (KDE...
Assessment and prediction of water quality parameters in Lake Köyceğiz using artificial neural network approach
Özçelik, Oya; Alp, Emre; Aksoy, Ayşegül; Department of Environmental Engineering (2015)
Water quality monitoring plays a significant role on water resources management and planning. European Union (EU) Water Framework Directive aims to achieve “good status” for all waters.. Within the adaptation period to EU, Turkey aims to improve its water quality monitoring network; however, this will lead to time, budget and human resources problems. Purpose of this thesis is the application of a method that will provide water quality assessment (WQA) under limited budget and data conditions. The method wa...
Development of water quality management strategies for the proposed Isikli reservoir
Gunduz, O; Soyupak, S; Yurteri, C (1998-01-01)
A two-dimensional laterally averaged hydrodynamic and water quality model (CE-QUAL-WS) is used to simulate the water quality behavior in the proposed Isikli Reservoir of the Ankara Water Supply System to determine appropriate strategies for the management of water quality.
