Water Source as a Driver of Landscape Irrigation Conservation Behavior: A Statewide Florida Study
(ASCE, 8/1/2020 1)Using the water source as a factor, a typology of residential irrigation water users was developed by segmenting 3,310 Floridians who used irrigation by their irrigation water source (i.e., well water, reclaimed water, ... -
Analytical Stochastic Microcomponent Modeling Approach to Assess Network Spatial Scale Effects in Water Supply Systems
(ASCE, 8/1/2020 1)End-uses at water supply systems typically follow a random pulse behavior, which blurs as consumptions are aggregated upstream, affecting flow rate variability along the spatial scale. Instantaneous variability has impact ... -
Optimizing Operating Rules for a Reservoir System in Northern China Considering Ecological Flow Requirements and Water Use Priorities
(ASCE, 7/1/2020 1)One of the most common ways of operating a reservoir system is to follow preestablished rules that specify the allowable releases at different time points of a year. Reservoir operating rules traditionally focus on human ... -
Spatial Assessment of Water-Use Vulnerability under Future Climate and Socioeconomic Scenarios within a River Basin
(ASCE, 7/1/2020 1)This case study developed a framework to assess the spatial distribution of water-use vulnerability within a river basin under various scenarios of climate change, climate change adaptation and mitigation strategies. Our ... -
Sequential Convex Optimization for Detecting and Locating Blockages in Water Distribution Networks
(ASCE, 8/1/2020 1)Unreported partially/fully closed valves or other types of pipe blockages in water distribution networks result in unexpected energy losses within the systems, which we also refer to as faults. We investigate the problem ... -
Well-Induced Stream Depletion and Groundwater Return Flow: Estimating Impact Schedules with a Finite-Difference Spreadsheet
(ASCE, 7/1/2020 1)Allocation of water from stream-aquifer systems must account for stream depletion from well withdrawal and for accretion from groundwater return flow. Both are subject to attenuation and delay. Transient impact assessment ... -
Probabilistic Assessment of Extended Detention Basins: Role of Model Parameter Uncertainty
(ASCE, 8/1/2020 1)This study investigates the role of parameter uncertainty on evaluation of stormwater control measures. Specifically, several formal and informal Bayesian uncertainty analysis techniques are linked with the modified Fair ... -
Application of Decision-Support Tools for Seasonal Water Supply Management that Incorporates System Uncertainties and Operational Constraints
(ASCE, 6/1/2020 1)Public water utilities face uncertain decisions every day in their efforts to meet drinking water needs of customers. Real-time decision-support tools (DST) are often used by water managers to solve a variety of water ... -
Effect of Pipe Size and Location on Water-Main Head Loss in Water Distribution Systems
(ASCE, 6/1/2020 1)This study discusses practical implications of considering unit head loss in different pipe sizes and in different locations of water distribution systems (WDSs) with regard to operation and maintenance. By visualizing ... -
Streaming Smart Meter Data Integration to Enable Dynamic Demand Assignment for Real-Time Hydraulic Simulation
(ASCE, 6/1/2020 1)Water distribution system models have long been widely used for design and planning purposes. Their application for supporting real-time operational decisions has been also gaining increasing interest over the past decade. ... -
Dynamic Pressure-Dependent Simulation of Water Distribution Networks Considering Volume-Driven Demands Based on Noniterative Application of EPANET 2
(ASCE, 6/1/2020 1)EPANET 2 software has been widely used among researchers and practitioners from its inception for hydraulic analysis. This technical note presents a method to simulate pressure-dependent volume-based demands in a single ... -
System Dynamics Simulation Model for Flood Management of the Three Gorges Reservoir
(ASCE, 7/1/2020 1)The operation of Three Gorges Reservoir (TGR) during flood seasons is of high importance for ensuring the wellbeing of the people living in the downstream flood-prone areas. Therefore, protecting the downstream areas from ... -
Operational Seasonal Water Supply and Water Level Forecasting for the Laurentian Great Lakes
(ASCE, 9/1/2020 1)Seasonal water supply forecasts are a critical component of regional water resources management planning. Across the United States, multiple modeling tools and operational protocols have evolved over time to address this ... -
Forecasting Water Demands in South Florida in the Context of Everglades Restoration: Retrospective
(ASCE, 11/1/2020 )Traditional economic forecasts had consistently underestimated the hypergrowth of South Florida and its need for freshwater from the 1970s through the 1990s. It was hypothesized that the continued rapid growth of urban and ... -
Quantifying the Impact of Compounding Influencing Factors to the Water Level Decline of China’s Largest Freshwater Lake
(ASCE, 6/1/2020 1)As a large open lake that connects to the lower Yangtze River, the Poyang Lake, China, has persisted dramatic water level decline since 2003. For better management of lake water resources and ecosystem, this study ... -
Simultaneous Hydraulic and Quality Model Calibration of a Real-World Water Distribution Network
(ASCE, 6/1/2020 1)Hydraulic and quality models are widely used in water distribution networks (WDNs) for assisting network analysis, design, and operation. In a calibrated model, the difference between the simulated and measured data reaches ... -
