Estimating Transition Probabilities in Markov Chain-Based Deterioration Models for Management of Wastewater Systems
(American Society of Civil Engineers, 2006)Accurate prediction of the current and future conditions of wastewater systems using available assessment data is crucial for developing appropriate proactive maintenance and rehabilitation strategies for an aging wastewater ... -
Derived Operating Rules for Allocating Recharges and Withdrawals among Unconnected Aquifers
(American Society of Civil Engineers, 2006)Six balancing rules are derived to inform short-term drawdown and recharge of water in multiple, unconnected aquifers. Management objectives are: (1) minimizing costs; (2) maximizing duration of operation; and (3) maximizing ... -
Downstream Economic Benefits of Conservation Development
(American Society of Civil Engineers, 2006)This paper evaluates the downstream hydrologic and economic impacts of development strategies that promote greater on-site storage of storm water. This paper applies a methodology to a specific case study that emphasizes ... -

Optimal Location of Infiltration-Based Best Management Practices for Storm Water Management
(American Society of Civil Engineers, 2005)A distributed hydrologic model of an urban watershed in the northeast United States was developed and combined with a genetic algorithm to determine the optimal location of infiltration-based best management practices ... -
Optimization of Water Distribution and Water Quality by Hybrid Genetic Algorithm
(American Society of Civil Engineers, 2005)This paper develops a multicommodity flow model to optimize water distribution and water quality in a regional water supply system. Waters from different sources with different qualities are considered as distinct commodities ... -
Case Study: Multicriteria Assessment of Drought Mitigation Measures
(American Society of Civil Engineers, 2005)The proactive approach to drought management is based on measures devised and implemented before, during, and after the drought event, according to a planning strategy rather than within an emergency framework. The measures ... -
Fuzzy Multiobjective Optimization of Water Distribution Networks
(American Society of Civil Engineers, 2005)An original approach to the optimal design of water distribution networks is presented in this paper. Multiobjective optimization is applied, i.e., minimizing costs and maximizing a benefit/quality function, the tradeoff ... -
Decision Support System for Reservoir Water Management Conflict Resolution
(American Society of Civil Engineers, 2005)A decision support system for reservoir water management conflict resolution (RWM-CRSS) in a multipurpose single reservoir system has been developed. The system consists of a communication system, a database management ... -
Leakage Assessment through Water Distribution Network Simulation
(American Society of Civil Engineers, 2005)Presented herein is a methodology for evaluation of water losses based on discrimination of the two components of uncontrolled water in a water distribution network: physical losses in mains and service connections, and ... -
Restoration of Pastureland Ecosystems: Case Study of Western Inner Mongolia
(American Society of Civil Engineers, 2005)Western Inner Mongolia is located in the downstream area of the Hei River Basin, the second largest inland basin in China. Since the 1960s, water depletion in the basin has increased very rapidly due to intensive irrigation ... -
Assessment of Regional Management Strategies for Controlling Seawater Intrusion
(American Society of Civil Engineers, 2005)Simulation-optimization methods, applied with adequate senstivitivity tests, can provide useful quantitative guidance for controlling seawater intrusion. This is demonstrated in an application to the West Coast Basin of ... -
Urban Storm Water Control Evaluation with Analytical Probabilistic Models
(American Society of Civil Engineers, 2005)In urban storm water management planning, a common problem associated with the widespread implementation of storage/treatment facilities, is the determination of the relative magnitudes of the storage capacity and the ... -
Securing Water Distribution Systems Using Online Contamination Monitoring
(American Society of Civil Engineers, 2005)The events of September 11, 2001 in the United States have brought to the fore the problem of drinking water distribution systems security. As a water distribution system is spatially diverse, limiting physical access to ... -
Case Study: Application of Multicriteria Decision Making to Urban Water Supply
(American Society of Civil Engineers, 2005)Presented herein is an attempt to put into practice the multicriteria decision making technique of compromise programming for a real urban water management case study in the city of Zahidan in Iran. Zahidan, the capital ... -
Pipeline Break Detection Using Pressure Transient Monitoring
(American Society of Civil Engineers, 2005)Sudden pipe breaks occur in water transmission pipelines and distribution mains. The consequences of these breaks can be very expensive because of the service interruption, the cost of repair, and damage to surrounding ... -
Optimal Maintenance Policy and Fund Allocation in Water Distribution Networks
(American Society of Civil Engineers, 2005)In maintenance of a water distribution network, the allocation of limited funds for maintenance among a network’s pipes and the decision to repair or replace a single pipe when failure occurs are the most important issues. ... -
Least-Cost Design of Water Distribution Networks under Demand Uncertainty
(American Society of Civil Engineers, 2005)Due to inherent variability in instantaneous water consumption levels, values of demands at nodes in a water distribution system remain one of the major sources of uncertainty in the network design process. Uncertainty in ... -
Climate-Based Estimation of Hydrologic Inflow into Lake Okeechobee, Florida
