Active Management of Environmental Water to Improve Ecological Outcomes
(American Society of Civil Engineers, 2018)Environmental water is being embraced by governments around the world as a means to partly restore rivers impacted by excessive river regulation and to protect those that are not yet overregulated. In cases where environmental ... -
Short-Term Water Demand Forecast Based on Deep Learning Method
(American Society of Civil Engineers, 2018)Short-time water demand forecasting is essential for optimal control in a water distribution system (WDS). Current methods (e.g., time-series models and conventional artificial neural networks) have limited power in ... -
Demand-Driven Spatiotemporal Variations of Flow Hydraulics and Water Age by Comparative Modeling Analysis of Distribution Network
(American Society of Civil Engineers, 2018)Distribution network modeling is proposed to investigate and manage water quality variations in a distribution network. Common practice in the modeling relies on pipe network simplification through skeletonization and uses ... -
Automated Strategic Prioritization Matchmaking Tool to Facilitate Federal–Community Adaptation Implementation
(American Society of Civil Engineers, 2018)Lack of available resources has been identified as a significant barrier for community implementation of climate adaptation actions. Although a broad array of federal resources exists, it is difficult for communities to ... -
Distance-Based Burst Detection Using Multiple Pressure Sensors in District Metering Areas
(American Society of Civil Engineers, 2018)It is a major challenge for water companies worldwide to quickly react to bursts so that water loss is reduced and service improved. This paper proposes a novel data-driven method for district metering areas (DMAs) with ... -
Urban Water Security Dashboard: Systems Approach to Characterizing the Water Security of Cities
(American Society of Civil Engineers, 2018)Urban water security is a major concern in the context of urbanization and climate change. Water security goes beyond having good infrastructure or good governance. Systems thinking can help in understanding the mechanisms ... -
Simulating Control Valves in Water Distribution Systems as Pipes of Variable Resistance
(American Society of Civil Engineers, 2018)This paper presents a simple valve simulation method integrable into the global gradient algorithm (GGA), which is widely used in hydraulic analysis of water distribution systems. In the proposed method, valves are treated ... -
Correlation of Energy Management Policies with Lower Energy Use in Public Water Systems
(American Society of Civil Engineers, 2018)One question in the increasingly frequent discussions about energy management among water utilities is whether energy management policies have any effect on their energy footprints. This study examines the question using ... -
Assessing the Impact of Climate Change on Environmental Outcomes in the Context of Natural Climate Variability
(American Society of Civil Engineers, 2018)Climate change has emerged as a key threat to river ecosystems. This study presents a generic, conceptual framework for assessing the significance of climate change impact for ecological outcomes. Within the framework, ... -
Hybrid Two-Stage Stochastic Methods Using Scenario-Based Forecasts for Reservoir Refill Operations
(American Society of Civil Engineers, 2018)Optimizing reservoir refill operations is important for improved water use. This study developed a real-time refill operation model using scenario-based forecasts. To bridge the gap between forecast horizon and operation ... -
Evaluation of Groundwater Resources in Response to Agricultural Management Scenarios in the Central Valley, California
(American Society of Civil Engineers, 2018)Dependence on groundwater throughout the Central Valley of California has resulted in severe and unsustainable groundwater depletion. In this research, we used the Central Valley hydrologic model (CVHM) to model how crop ... -
Model for Real-Time Operations of Water Distribution Systems under Limited Electrical Power Availability with Consideration of Water Quality
(American Society of Civil Engineers, 2018)A new methodology is presented for real-time operation of water distribution systems (WDS) under the critical condition of limited electrical energy. The critical conditions could arise due to electric grid failure, extreme ... -
Hydraulic and Electric Regulation of a Prototype for Real-Time Control of Pressure and Hydropower Generation in a Water Distribution Network
(American Society of Civil Engineers, 2018)Coupling pressure management and energy recovery in water distribution networks (WDNs) is an appealing topic in the field of optimal management of water systems. The use of turbines or pumps as turbines (PATs) allows for ... -
Renegotiations of Water Concessions: Empirical Analysis of Main Determinants
(American Society of Civil Engineers, 2018)The private sector has been increasingly involved in the construction, management, and operation of water systems. There are several models for private-sector participation, but concessions have been made among the preferred ... -
Inexact Copula-Based Stochastic Programming Method for Water Resources Management under Multiple Uncertainties
(American Society of Civil Engineers, 2018)Extensive uncertainties exist in many resources and environmental management problems, which can be interrelated and thus amplify the complexity and nonlinearity of study systems. The interactions from dependent random ... -
Operation and Cost-Effectiveness of Local and Remote RTC
(American Society of Civil Engineers, 2018)This paper analyses the cost-effectiveness of two different variants of real-time pressure control (RTC) of valves in water distribution networks (WDNs), namely, the local and remote RTC. The system considered for RTC ... -
