Investigating the Sensitivity of U.S. Streamflow and Water Quality to Climate Change: U.S. EPA Global Change Research Program’s 20 Watersheds Project
(American Society of Civil Engineers, 2012)The U.S. EPA’s Global Change Research Program (GCRP) recently began an effort to address gaps in the current knowledge of the sensitivity of U.S. streamflow, nutrient (nitrogen and phosphorus), and sediment loading to ... -
Short-Term Scheduling for Large-Scale Cascaded Hydropower Systems with Multivibration Zones of High Head
(American Society of Civil Engineers, 2012)Construction of huge hydropower plants in the southern region of China has been rapidly increasing in recent years. These plants usually have multiple vibration zones of high head that have a great effect on short-term ... -
Hybrid Water Demand Forecasting Model Associating Artificial Neural Network with Fourier Series
(American Society of Civil Engineers, 2012)This paper addressed the problem of water-demand forecasting for real-time operation of water supply systems. The present study was conducted to identify the best fit model using hourly consumption data from the water ... -
Losses Reduction and Energy Production in Water-Distribution Networks
(American Society of Civil Engineers, 2012)During the past few years, issues concerning sustainable management of water distribution systems have attracted interest through an integrated policy aimed at reducing leakage through a pressure management strategy. ... -
Kernel Function Model for Planning of Agricultural Groundwater Development
(American Society of Civil Engineers, 2012)A linked kernel-optimization model for the planning of optimal groundwater development for irrigation is presented. The planning ensures optimization of zonal crop patterns subject to the constraints on the maximum water ... -
Staged Climate Change Adaptation Planning for Water Supply in Amman, Jordan
(American Society of Civil Engineers, 2012)This research develops a multistage stochastic linear programming (LP) model to assist in the process of water system planning and management under demographic and climate change in Amman, Jordan, over the next 75 years. ... -
Estimating and Verifying United States Households’ Potential to Conserve Water
(American Society of Civil Engineers, 2012)Behavior and technological impacts on residential indoor water use and conservation efforts in the United States are identified. Preexisting detailed end-use data was collected before and after toilets, faucets, showerheads, ... -
Statistical and Dynamical Climate Predictions to Guide Water Resources in Ethiopia
(American Society of Civil Engineers, 2012)Climate predictions with lead times of one season or more often provide prospects for exploiting climate-related risks and opportunities. This motivates the evaluation of precipitation prediction techniques from statistical ... -
550-Year Reconstruction of Streamflow Variability in Spring Valley, Nevada
(American Society of Civil Engineers, 2012)Spring Valley, Nevada, is one of several areas proposed for the pumping and export of ground-water to Las Vegas by the Southern Nevada Water Authority. Long-term annual-to-decadal variability of water supply in the region ... -
Sensitivity of Optimal Tradeoffs between Cost and Greenhouse Gas Emissions for Water Distribution Systems to Electricity Tariff and Generation
(American Society of Civil Engineers, 2012)Increased awareness of climate change has shifted the focus of water distribution system (WDS) optimization research from cost minimization only to the incorporation of energy or associated greenhouse gas (GHG) minimization. ... -
Identifying Sampling Interval for Event Detection in Water Distribution Networks
(American Society of Civil Engineers, 2012)It is a generally adopted policy, albeit unofficially, to sample flow and pressure data at a 15-min interval for water distribution system hydraulic measurements. Further, for flow, this is usually averaged, whereas pressure ... -
Reducing the Complexity of Multiobjective Water Distribution System Optimization through Global Sensitivity Analysis
(American Society of Civil Engineers, 2012)This study investigates the use of global sensitivity analysis as a screening tool to reduce the computational demands associated with multiobjective design and rehabilitation of water distribution systems (WDS). Sobol’s ... -
Revisiting Optimal Water-Distribution System Design: Issues and a Heuristic Hierarchical Approach
(American Society of Civil Engineers, 2012)For the past three decades, a number of studies have been dedicated to water-distribution system (WDS) optimal design using alternative optimization algorithms. Many of those, however, focused on the introduction and ... -
California’s Sacramento–San Joaquin Delta Conflict: From Cooperation to Chicken
(American Society of Civil Engineers, 2012)California’s Sacramento-San Joaquin Delta is the major hub of California’s water supply system and is central to the ecosystem of many native threatened and endangered species. Conflicts over the Delta have evolved over ... -
Real-Time Water Quality Monitoring: Assessment of Multisensor Data Using Bayesian Belief Networks
(American Society of Civil Engineers, 2012)Real-time sensing in water distribution systems provides a potentially powerful analytical tool for providing water security. Through monitoring surrogate parameters (e.g., pH, turbidity, and residual chlorine) over time, ... -
Chemical Water Stability in Optimal Operation of Water Distribution Systems with Blended Desalinated Water
(American Society of Civil Engineers, 2011)This work presents a model for the inclusion of chemical water stability in optimizing the operation of water distribution systems. When desalinated water is mixed with surface water and/or groundwater, the blend can become ... -
Planning-Level Capital Cost Estimates for Pumping
