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...
Identification of the Best Booster Station Network for a Water Distribution System
AYVAZ, MUSTAFA TAMER; Kentel Erdoğan, Elçin (American Society of Civil Engineers (ASCE), 2015-05-01)
A fuzzy decision-making framework (DMF) is combined with a hybrid genetic algorithm-linear programming (GA-LP) optimization approach to determine the best booster station network for a water distribution system. The proposed hybrid GA-LP model simultaneously optimizes two conflicting objectives; namely, minimization of total chlorine injection dosage and the number of booster stations. At the same time, residual chlorine concentrations are kept within desired limits. Adjustment of the relative importance of...
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...
Genetic algorithm for constrained optimization models and its application in groundwater resources management
Guan, Jiabao; Kentel Erdoğan, Elçin; Aral, Mustafa M. (American Society of Civil Engineers (ASCE), 2008-01-01)
Genetic algorithms (GAs) have been shown to be an efficient tool for the solution of unconstrained optimization problems. In their standard form, GA formulations are "blind" to the constraints of an optimization model when the model involves these constraints. Thus, in GA applications alternative procedures are used to satisfy the constraints of the optimization model. In this study, the method that is utilized in the Complex Algorithm to solve constrained optimization problems is abstracted to develop a re...
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...
