2D Multilevel Model for Flood Wave Propagation in Flood-Affected Areas
(American Society of Civil Engineers, 1998)A hyperbolic model for the simulation of flood wave propagation on initially dry land is presented. The convective inertia terms are neglected in the momentum equations. This assumption allows the use of a finite element ... -
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 ... -
A <i>CE-QUAL-W2</i> Model of Neuse Estuary for Total Maximum Daily Load Development
(American Society of Civil Engineers, 2003)In support of a total maximum daily load (TMDL) analysis, hydrodynamic and water quality conditions in the Neuse River Estuary were simulated for a 43 month period beginning in June 1996 using the two-dimensional, laterally ... -

A Comparative Assessment of Municipal Water Use in Turkey
(ASCE, 2021-12-15)The use of assessment methods is essential for proper planning, improvement of the water system, and water economy in municipal water management. Thus, statistical model approaches can be used to evaluate the factors ... -
A Comprehensive Review of the Nexus of Food, Energy, and Water Systems: What the Models Tell Us
(ASCE, 2022-04-12)The world faces mounting challenges related to food, energy, and water security. Modeling approaches have emerged in the last decade to address this problem with mixed outcomes across a range of boundaries, including local, ... -
A Content-Based Active-Set Method for Pressure-Dependent Models of Water Distribution Systems with Flow Controls
(ASCE, 2020)In this paper a new method is proposed that solves for the steady state of pressure-dependent models (PDMs) with flow control valves. Rather than model flow devices individually, the method solves the more general problem ... -
A Dynamic Adaptive Approach for Water Distribution Network Design
(American Society of Civil Engineers, 2019)In the face of a highly uncertain future, there is a need for water utilities to develop structured approaches for the long-term strategic design of water distribution networks (WDNs). A new conceptual framework for ... -
A Graph Theory-Based Layout Algorithm for PRVs Placement and Setpoint Determination in Water Distribution Systems
(ASCE, 2022-01-31)This paper presents a new valve positioning algorithm (VPA) for water network pressure reduction. The proposed algorithm is a graph theory-based algorithm combined with EPANET2.2 to position pressure-reducing valves (PRVs) ... -
A Heuristic for Strategic Valve Placement
(ASCE, 2021-12-13)An iterative heuristic is proposed to improve the distribution of isolation valves within an existing water distribution network to decrease the magnitude of service interruptions while using the minimum number of valves ... -
A Hydroeconomic Simulation-Optimization Framework to Assess the Cooperative Game Theory in Coastal Groundwater Management
(ASCE, 2021-10-27)In this study, a cooperative game theory framework is proposed to investigate how the cooperation of groundwater consumers influences the reduction in environmental damages and benefit the stakeholders in coastal regions. ... -
A Mixed-Integer Linear Optimization Model for Reservoir Sizing Incorporating Performance Measures: Deterministic and Stochastic Frameworks
(ASCE, 2022/05/11)This paper proposes an optimal sizing strategy for water storage reservoirs that takes into account the minimum allowed number of failure periods (measure of reliability) and the maximum allowed failure magnitude (measure ... -
A Multicriteria Evaluation Based on the Grey-TOPSIS Method for Water Distribution Companies in Brazil
(ASCE, 2024/05/01)The use of performance indicator systems is essential to evaluate the performance of water supply systems. They allow the quantification of the goals and objectives for service provision and are presented as the best ... -
A New Perspective on Assessing the Real Water Savings Resulting from Irrigation Technology Interventions
