Storm-Water Investment Strategy Evaluation Model for Impaired Urban Watersheds
(American Society of Civil Engineers, 2012)The stormwater investment strategy evaluation (StormWISE) model identifies the mix of characteristics that storm-water retrofit projects should have in an impaired watershed to maximize multiple water quality benefits ... -
Multiobjective Evolutionary Computation Approach for Redesigning Water Distribution Systems to Provide Fire Flows
(American Society of Civil Engineers, 2012)One of the critical public safety roles for water distribution systems (WDS) is suppression of urban fire events. Previous studies have investigated WDS rehabilitation with a major focus on improving reliability by pipe ... -
Evaluating the Impact of Climate Change Mitigation Strategies on the Optimal Design and Expansion of the Amherstview, Ontario, Water Network: Canadian Case Study
(American Society of Civil Engineers, 2012)The objective of this paper is to assess the impact of proposed Canadian climate change mitigation policies (discounting and carbon pricing) on cost, energy use, and greenhouse gas (GHG) emissions in the single-objective ... -
Applying Network Theory to Quantify the Redundancy and Structural Robustness of Water Distribution Systems
(American Society of Civil Engineers, 2012)A water distribution system, represented as a spatially organized graph, is a complex network of multiple interconnected nodes and links. The overall robustness of such a system, in addition to the reliability of individual ... -
Dual Water Distribution Network Design under Triple-Bottom-Line Objectives
(American Society of Civil Engineers, 2012)Rapid urban growth has stressed limited supplies of high-quality water sources and water shortage has become a major issue in worldwide. Today, sustainable water supply to meet growing demand is a significant concern for ... -
False Negative/Positive Issues in Contaminant Source Identification for Water-Distribution Systems
(American Society of Civil Engineers, 2012)A contaminant source identification (CSI) methodology for water distribution systems is intended to identify possible events (i.e., intrusion nodes, times, duration, and mass rate). The methodology has to be both rapid and ... -
Boolean Integer Nonlinear Programming for Water Multireservoir Operation
(American Society of Civil Engineers, 2012)In this paper, the optimal pump operation of reservoirs or tank system is considered. The pump operation optimization problem is formulated as a Boolean integer nonlinear programming (BINLP) problem to minimize the cost ... -
Incorporating Climate Uncertainty in a Cost Assessment for New Municipal Source Water
(American Society of Civil Engineers, 2012)Though new water supply source development has always required planning under many forms of uncertainty, climate change presents an added dimension that may exacerbate supply and water quality challenges. Hence, new ... -
Simulating Nonresidential Water Demand with a Stochastic End-Use Model
(American Society of Civil Engineers, 2011)The end-use model SIMDEUM for residential water demand has been extended to incorporate nonresidential water demand. The model was developed to predict water-demand patterns with a small timescale (1 s) and small spatial ... -
Burst Detection in Water Networks Using Principal Component Analysis
(American Society of Civil Engineers, 2012)The following work presents a multivariate statistical technique applied to the control of water inflows into district metering areas (DMAs) of urban networks. This technique, called principal-component analysis (PCA), ... -
Assessment of Flow Regulation Effects by Dams in the Han River, Korea, on the Downstream Flow Regimes Using SWAT
(American Society of Civil Engineers, 2012)This study suggests a method for precise assessment of the effects of flow regulation by dams on downstream flow regimes, using a daily runoff simulation model. The soil and water assessment tool (SWAT) was used to evaluate ... -
Optimization of Large-Scale Hydrothermal System Operation
(American Society of Civil Engineers, 2012)This paper presents the development of a mathematical model to optimize the management and operation of the Brazilian hydrothermal system. The system consists of a large set of individual hydropower plants and a set of ... -
