Ethiopia’s Grand Renaissance Dam: Implications for Downstream Riparian Countries
(American Society of Civil Engineers, 2015)Ethiopia has begun seriously developing their significant hydropower potential by launching construction of the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile River to facilitate local and regional growth. The ... -
Inexact Probabilistic Optimization Model and Its Application to Flood Diversion Planning in a Dynamic and Uncertain Environment
(American Society of Civil Engineers, 2015)Flood management systems involve a variety of complexities, such as multiple uncertainties and their interdependences, as well as multiregion and dynamic features. This paper thus presents an inexact two-stage mixed-integer ... -
Leak Detection and Localization through Demand Components Calibration
(American Society of Civil Engineers, 2016)Success in the application of any model-based methodology (e.g., design, control, supervision) highly depends on the availability of a well-calibrated model. The calibration of water distribution networks needs to be ... -
Inexact Multistage Fuzzy-Stochastic Programming Model for Water Resources Management
(American Society of Civil Engineers, 2015)In this study, an inexact multistage fuzzy-stochastic programming (IMFSP) model was developed for water resources management under uncertainty. In the IMFSP model, the uncertainties existing in the objective functions, and ... -
Integration of Physiographic Drainage-Inundation Model and Nondominated Sorting Genetic Algorithm for Detention-Pond Optimization
(American Society of Civil Engineers, 2015)The study aims to propose a simulation-optimization model for deciding the optimal combination of detention ponds, which comprises a two-dimensional physiographic drainage-inundation model and a nondominated sorting genetic ... -
Parallel Evolutionary Algorithm for Designing Water Distribution Networks to Minimize Background Leakage
(American Society of Civil Engineers, 2016)Leaks in water distribution systems waste energy and water resources, increase damage to infrastructure, and may allow contamination of potable water. This research develops an evolutionary algorithm-based approach to ... -
Sensitivity Analysis for Sampling Design and Demand Calibration in Water Distribution Networks Using the Singular Value Decomposition
(American Society of Civil Engineers, 2015)Research in water distribution networks during recent decades has often focused on calibration. There is no unique solution for this problem as the methodologies are developed depending on which parameters have to be ... -
Seismic Hazard Assessment Model for Urban Water Supply Networks
(American Society of Civil Engineers, 2016)A new seismic reliability evaluation model is proposed that quantifies the impact of earthquakes on hydraulic behavior of water supply networks. Probabilistic seismic events are produced in the target areas, and the depth ... -
Sustainability Review of Water-Supply Options in the Los Angeles Region
(American Society of Civil Engineers, 2015)The City of Los Angeles, with a population reaching 4 million people in 2013, imports nearly 90% of its water from sources outside the city. However, climate change, population growth, competing demands, water quality ... -
Redesigning Water Distribution Networks Using a Guided Evolutionary Approach
(American Society of Civil Engineers, 2016)The paper describes and discusses the application of a guided evolutionary approach for the optimization of water distribution networks. Initially developed for the Battle of the Water Networks II (BWN-II), the approach ... -
Hybrid Evolutionary Optimization/Heuristic Technique for Water System Expansion and Operation
(American Society of Civil Engineers, 2016)This paper presents a methodological solution to The Battle of Background Leakage Assessment for Water Networks (BBLAWN) competition. The methodology employs two constrained multiple-objective optimization problems and is ... -
Multistep Approach for Optimizing Design and Operation of the C-Town Pipe Network Model
(American Society of Civil Engineers, 2016)A multiobjective approach is used here to optimize design and operation of the C-Town pipe network, searching for trade-off solutions between (1) installation cost, (2) operational cost, and (3) cost of the pressure-reducing ... -
Successive Linear Programming Approach Applied to BBLAWN
(American Society of Civil Engineers, 2016)The battle of background leakage assessment for water networks (BBLAWN) challenge was approached using successive linear programming. A linear representation was solved successively for the nonlinear constraints of headloss, ... -
Detection of Water Meter Under-Registration Using Statistical Algorithms
(American Society of Civil Engineers, 2016)Meter tampering is an important problem for utilities (both power and water distribution) to address because they represent an important loss of income. The authors’ group at the Electronic Technology Department of the ... -
