Sizing Municipal Storage Tanks Based on Reliability Criteria
(American Society of Civil Engineers, 2008)Municipal storage tanks are used to balance differences in supply and demand. Tanks have traditionally been sized based on deterministic criteria for balancing, fire, and emergency storage components. In this paper a ... -
Efficient Sensor Placement Optimization for Securing Large Water Distribution Networks
(American Society of Civil Engineers, 2008)The problem of deploying sensors in a large water distribution network is considered, in order to detect the malicious introduction of contaminants. It is shown that a large class of realistic objective functions—such as ... -
Discussion of “Drought Storage Allocation Rules for Surface Reservoir Systems” by J. R. Lund
(American Society of Civil Engineers, 2008) -
Optimizing Retention Basin Networks
(American Society of Civil Engineers, 2008)Retention basins are an effective and common means of flood control. Differing from detention, retention fully contains a particular storm event, using infiltration as the primary means of disposal. For a complex watershed ... -
Integrating Long- and Short-Term Reservoir Operation Models via Stochastic and Deterministic Optimization: Case Study in Japan
(American Society of Civil Engineers, 2008)Real-time reservoir operation models carried out under short operating horizons have no information about the seasonal changes in streamflow. The overall operation may improve provided that long-term information can be ... -
Solving Unconfined Groundwater Flow Management Problems with Successive Linear Programming
(American Society of Civil Engineers, 2008)Groundwater management models are often applied to problems in which the aquifer state is a mildly nonlinear function of managed stresses. The use of the successive linear programming algorithm to solve such problems is ... -
Reliability and Remediation Cost of Optimal Remediation Design Considering Uncertainty in Aquifer Parameters
(American Society of Civil Engineers, 2008)Reliability of a “preassumed” optimal remediation design using a pump and treat method is evaluated. A “true” hydraulic conductivity field with a certain spatial correlation is supposed. Hydraulic conductivity values are ... -
Importance of Exposure Model in Estimating Impacts When a Water Distribution System Is Contaminated
(American Society of Civil Engineers, 2008)The quantity of a contaminant ingested by individuals using tap water drawn from a water distribution system during a contamination event depends on the concentration of the contaminant in the water and the volume of water ... -
Heuristic Approach for Operational Response to Drinking Water Contamination
(American Society of Civil Engineers, 2008)This paper introduces a simple topological approach to systematize the isolation of contaminated areas within the pressure zones of drinking water distribution systems (DWDSs). Assuming optimal location of contaminant ... -
Game Theoretical Approach to Conflict Resolution in Transboundary Water Resources Management
(American Society of Civil Engineers, 2008)Management of transboundary water resources has been the focus of many studies due to the observed water stress all over the globe combined with the continually increasing water demand. States sharing water resources often ... -
Evaluation of a Modeling Approach to Assess Nitrogen Assimilative Capacity due to River Restoration
(American Society of Civil Engineers, 2008)To improve water quality and enhance habitat for fish and wildlife, a restoration project was initiated on the Truckee River at McCarran Ranch, Nevada. A water quality model was parameterized using Hydrologic Simulation ... -
Practical Remedial Design Optimization for Large Complex Plumes
(American Society of Civil Engineers, 2008)Powerful simulation/optimization (S/O) models exist for designing groundwater well systems and pumping strategies. However, it can be challenging to use S/O modeling effectively for large, complex, and computationally ... -
Inexact Chance-Constrained Linear Programming Model for Optimal Water Pollution Management at the Watershed Scale
(American Society of Civil Engineers, 2008)An inexact chance-constrained linear programming (ICCLP) model for optimal water pollution management at the watershed scale was developed. We selected the net expenditures of the alternative strategies, including initial ... -
Evaluation of the Minimum Discharge from the Dam on Menta Stream (Reggio Calabria, Italy)
(American Society of Civil Engineers, 2008)Many anthropic factors may contribute to the alteration of the natural evolution of the river environment. Among them, probably the most severe is the regulation of the stream flow by a dam. To minimize this impact normally ... -
Adding Radar Rainfall and Calibration to the TR-20 Watershed Model to Improve Dam Removal Flood Analysis
(American Society of Civil Engineers, 2008)In communities where flood frequency data are unavailable, rainfall-runoff-routing models can estimate flood impacts of dam removal. We used the federal TR-20 model with PEST calibration software and NEXRAD radar rainfall ... -
Ant Colony Optimization for Optimal Control of Pumps in Water Distribution Networks
(American Society of Civil Engineers, 2008)Reducing energy consumption of water distribution networks has never had more significance than today. The greatest energy savings can be obtained by careful scheduling of operation of pumps. Schedules can be defined either ... -
Multiobjective Contaminant Sensor Network Design for Water Distribution Systems
(American Society of Civil Engineers, 2008)A contaminant intentional intrusion into a water distribution system is one of the most difficult threats to address. This is because of the uncertainty of the type of the injected contaminant and its consequences, and the ... -
Chance Constrained Optimal Design of Trapezoidal Channels
(American Society of Civil Engineers, 2008)The development of a mathematical model for chance constrained optimal design of trapezoidal channels is presented. The developed model maximizes the probability of channel capacity being greater than the design flow, and ... -
Identifying Sets of Key Nodes for Placing Sensors in Dynamic Water Distribution Networks
(American Society of Civil Engineers, 2008)The design of a sensor-placement scheme capable of detecting all possible contamination events for a water distribution system before consumers are put at risk is essentially impossible given current technologies and ... -
Consequence Management Utilizing Optimization
(American Society of Civil Engineers, 2008)Following the identification of a contaminant in a water distribution network, a variety of response actions must be examined in order to implement the most beneficial consequence management strategy. Optimization techniques ...
