Integrated Management of Irrigation and Urban Storm-Water Infiltration
(American Society of Civil Engineers, 2006)New microscale techniques have become available to assist urban designers in better water management. Urban water management has focused on two different areas: storm water and water supply. The focus of storm-water ... -
Drought Storage Allocation Rules for Surface Reservoir Systems
(American Society of Civil Engineers, 2006)This technical note develops a simple drought storage allocation rule to minimize evaporative and seepage water losses from a system of reservoirs. Such a rule might have value during a prolonged drought, when the value ... -
Individual and Societal Responses to Natural Hazards

Locating Monitors in Water Distribution Systems: Red Team–Blue Team Exercise
(American Society of Civil Engineers, 2006)Red team–blue team exercises are methods of evaluating security by creating a “game” where one team (the red team) attempts to “attack” a target and the other team (the blue team) tries to defend it. This paper describes ... -
Consequence Management Optimization for Contaminant Detection and Isolation
(American Society of Civil Engineers, 2006)Vulnerability assessments may be used to help identify components of water distribution systems that require strengthening against possible attacks, including physical destruction and/or chemical contamination. Numerous ... -
Model for Estimating Acute Health Impacts from Consumption of Contaminated Drinking Water
(American Society of Civil Engineers, 2006)Disease transmission models predict the spread of disease over time through susceptible, infected, and recovered populations, and are commonly used to design public health intervention strategies. A modified disease model ... -
Optimization of Frequency Distribution of Storm-Water Discharges for Coastal Ecosystem Restoration
(American Society of Civil Engineers, 2006)Many coastal ecosystems have been adversely impacted by increased storm-water drainage due to expanding urbanization. The ecosystem of the St. Lucie Estuary (SLE), located on the east coast of south Florida, has been greatly ... -
Distribution System Contamination Events: Exposure, Influence, and Sensitivity
(American Society of Civil Engineers, 2006)This paper presents a two-part investigation of the response of municipal water distribution systems to contamination events. In Part I of the investigation, a contamination event was modeled as a steady -
Elevation Dependent Management of the Edwards Aquifer: Linked Mathematical and Dynamic Programming Approach
(American Society of Civil Engineers, 2006)This study addresses the dynamic issue of optimum pumping and optimum target ending aquifer elevation. A stochastic dynamic programming (DP) approach is used to address this optimal elevation question. The analytical ... -
Impact of Sensor Detection Limits on Protecting Water Distribution Systems from Contamination Events
(American Society of Civil Engineers, 2006)Real-time water quality sensors are becoming commonplace in water distribution systems. However, field deployable, contaminant-specific sensors are still in the development stage. As development proceeds, the necessary ... -
Comparison of Physical Sampling and Real-Time Monitoring Strategies for Designing a Contamination Warning System in a Drinking Water Distribution System
(American Society of Civil Engineers, 2006)Protecting the water systems of the United States from terrorist attacks has become a federal and local priority. Routine sampling and analysis has been proposed as a potential monitoring approach that could be used to ... -
Identification of Contaminant Sources in Water Distribution Systems Using Simulation–Optimization Method: Case Study
(American Society of Civil Engineers, 2006)In this paper, the authors propose a new approach, the simulation–optimization method, to solve a nonlinear contaminant-source and release-history identification problem for a complex water distribution system. This approach ... -
Reduction of Physical Threats to Water Distribution Systems1
(American Society of Civil Engineers, 2006)The potential threats to U.S. water supply systems have changed fundamentally in the past 4 years. Prior to 2001, the major threats were natural causes, accidents, and some malicious behavior by a small group of individuals. ... -
Estimating 7Q10 Confidence Limits from Data: A Bootstrap Approach
(American Society of Civil Engineers, 2006)7Q10 streamflow estimates used to support modeling and data analysis under the Clean Water Act national pollution discharge elimination system and total maximum daily load programs can have direct environmental and economic ... -
Mixed-Integer Approach for Obtaining Unique Solutions in Source Inversion of Water Networks
(American Society of Civil Engineers, 2006)This paper addresses the problem of contamination source determination in municipal drinking water networks. In previous work, the authors introduced a large-scale nonlinear programming approach for identifying both the ... -

Contamination Source Identification in Water Systems: A Hybrid Model Trees–Linear Programming Scheme
(American Society of Civil Engineers, 2006)This paper presents a new approach for contamination source identification in water distribution systems through a coupled model trees–linear programming algorithm. Model trees are an extension of regression trees (regression ... -
Sensor Placement in Municipal Water Networks with Temporal Integer Programming Models
(American Society of Civil Engineers, 2006)We present a mixed-integer programming (MIP) formulation for sensor placement optimization in municipal water distribution systems that includes the temporal characteristics of contamination events and their impacts. Typical ... -
Contamination Warning in Water Networks: General Mixed-Integer Linear Models for Sensor Location Design
(American Society of Civil Engineers, 2006)A mixed-integer linear program is proposed to identify optimal sensor locations for early warning against accidental and intentional contaminations in drinking water distribution systems. The general model can be applied ... -
Bayesian Belief Networks to Integrate Monitoring Evidence of Water Distribution System Contamination
(American Society of Civil Engineers, 2006)A Bayesian belief network (BBN) methodology is proposed for combining evidence to better characterize contamination events and reduce false positive sensor detections in drinking water distribution systems. A BBN is developed ...
