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 existing nonlinear codes. The solution of the optimization problem is obtained by interfacing a hydraulic and water quality simulation code, EPANET, with a nonlinear optimization code, GRG2. Bound constraints on the state variables are incorporated into the objective function using the augmented Lagrangian penalty method. Three objective functions were used in the model to minimize (1) the deviations of actual substance concentrations from desired concentration values; (2) the total pump duration times; or (3) the total energy cost. The effectiveness of the methodology was tested using a hypothetical water distribution system. All three objective functions were capable of finding an optimal pumping schedule with water quality considerations.

Impacts of physical and chemical heterogeneities on aquifer remediation design Aksoy, Ayşegül (American Society of Civil Engineers (ASCE), 2004-07-01) The impacts of physical and chemical aquifer heterogeneities on optimal remediation design, costs, and time to compliance are investigated by linking a genetic algorithm with a contaminant transport simulation model. Physical and chemical aquifer heterogeneities were grouped into three levels as follows: (1) hydraulic conductivity (K) heterogeneity only; (2) combined heterogeneity of K and the distribution coefficient (Kd); and (3) combined heterogeneity of K, Kd, and the mass transfer rate (α). Various deg...
Optimal operation of water distribution systems for water quality purposes Altan Sakarya, Ayşe Burcu (1999-06-09) 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 nonline...
Evaluating the success of public participation in water resources management: five key constituents Oezerol, Guel; Newig, Jens (IWA Publishing, 2008-01-01) Public participation ( PP) is increasingly expected to enhance the effectiveness of water resources management. This is recognized in recent legislation such as the European Union Water Framework Directive. We identify five key constituents that affect the success of PP processes and which can be used as indicators thereof. These comprise: 1) the scope of the participants; 2) communication with the public; 3) capacity building; 4) timing; and 5) financing of participation. They are based on the management o...
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...
Diverging Water Management Paradigms between Turkey and the European Union Kibaroğlu, Ayşegül; SÜMER, VAKUR (Informa UK Limited, 2007-01-01) Since the early 1990s, the integrated water resources management (IWRM) approach has been championed and adopted by some of the industrialized states. The present paper analyzes the IWRM approach through an historical narrative while emphasizing divergences in the priorities and requirements of the developing and developed countries. Then, the paper examines water resources management in Turkey taking into consideration the political and economic structure of the country. Turkey, being the accession country...
