Improving Short-Term Urban Water Demand Forecasts with Reforecast Analog Ensembles
(American Society of Civil Engineers, 2016)Urban water demand forecasting is key to municipal water supply management. Short-term urban water demands are influenced by weather conditions. Thus, short-term urban water demand forecasting could be improved by using ... -
Smart Meter Analytics to Pinpoint Opportunities for Reducing Household Water Use
(American Society of Civil Engineers, 2016)Knowledge of when, how, and by whom water is being used is crucial for planning ways to conserve drinking water. The goal of this paper is to identify groups of similar households (whom) based on their regular high-magnitude ... -
Testing Contamination Source Identification Methods for Water Distribution Networks
(American Society of Civil Engineers, 2016)In the event of contamination in a water distribution network (WDN), source identification (SI) methods that analyze sensor data can be used to identify the source location(s). Knowledge of the source location and ... -
Leakage as Pressure-Driven Demand in Design of Water Distribution Networks
(American Society of Civil Engineers, 2016)The loss of some amount of water through leaks is inevitable in a water distribution network (WDN). Usually, leakage losses are included as volume-based demands by increasing the nodal demands by a certain percentage in ... -
Generalized Mathematical Simulation Formulation for Reservoir Systems
(American Society of Civil Engineers, 2016)Components of a water resource system (WRS) can be assessed and evaluated by employing simulation and optimization techniques. In general, simulation models are used to evaluate the behavior and function of systems under ... -
Estimating Water Supply Infrastructure Cost Using Regression Techniques
(American Society of Civil Engineers, 2016)The current paper aims at the establishment and validation of reference cost functions for different types of assets of water supply systems based on known hydraulic (e.g., flow, pump head, pump power) and physical ... -
Identifying High Power–Density Stream Reaches through Refined Geospatial Resolution in Hydropower Resource Assessment
(American Society of Civil Engineers, 2016)Aided by the rapid development of multiple geospatial data sets for topography, hydrology, and existing energy-water infrastructures, reconnaissance-level hydropower resource assessment can now be conducted using geospatial ... -
Framework for Forensic Investigation of Associations between Operational States and Pipe Failures in Water Distribution Systems
(American Society of Civil Engineers, 2016)Water distribution systems throughout the world are deteriorating in part due to corrosion of cast iron pipes. Developing a deeper understanding of the operational association with failure may lead to operational improvements ... -
Sensitivity Analysis of a Transient-Based Frequency Domain Method for Extended Blockage Detection in Water Pipeline Systems
(American Society of Civil Engineers, 2016)Partial blockages are commonly formed in water supply pipelines due to many factors, such as deposition, biofilm, and corrosion in the natural water supply process, as well as valve throttle in the artificial construction ... -
Observability Analysis in Water Transport Networks: Algebraic Approach
(American Society of Civil Engineers, 2016)State estimation (SE) techniques are being applied to different network systems in order to convert system measurements into real information about the network state. SE applications to water systems are relatively novel, ... -
Quest for a New Solver for EPANET 2
(American Society of Civil Engineers, 2016)One of the best known hydraulic water distribution modeling toolkits that is most used by both researchers and practitioners is -
Design and Evaluation of Irrigation Water Pricing Policies for Enhanced Water Use Efficiency
(American Society of Civil Engineers, 2016)Utilizing economic instruments, especially water pricing, is a useful strategy in the management of water demand. In this study, water pricing policies along with incentive strategies through subsidies to farmers are ... -
Hydraulic Simulation Techniques for Water Distribution Networks to Treat Pressure Deficient Conditions
(American Society of Civil Engineers, 2016)Hydraulic analysis schemes for water distribution networks can be divided into demand-driven analysis (DDA) and pressure-driven analysis (PDA) according to the ways of calculating available outflow at nodes based on the ... -
Tailoring Seasonal Time Series Models to Forecast Short-Term Water Demand
(American Society of Civil Engineers, 2016)This paper presents a methodology to forecast short-term water demands either offline or online by combining seasonal autoregressive integrated moving average (SARIMA) models with data assimilation. In offline mode, the ... -
Optimization Model for BMP Selection and Placement in a Combined Sewer
(American Society of Civil Engineers, 2016)The purpose of this study is to develop an optimization model for the selection and placement of best management practice (BMP) at the watershed level in order to control water quantity and quality. Linear programming (LP) ... -
Nine Decades of Salinity Observations in the San Francisco Bay and Delta: Modeling and Trend Evaluations
(American Society of Civil Engineers, 2016)The position of the low salinity zone in the San Francisco Bay Delta—given its correlation with the abundance of several estuarine species—is used for water management in a system that supplies water to more than 20 million ... -
