Stochastic Method for Examining Vulnerability of Hydropower Generation and Reservoir Operations to Climate Change: Case Study of the Dworshak Reservoir in Idaho
(American Society of Civil Engineers, 2014)Changes in air temperature and precipitation that are due to climate change can affect operational objectives and hydropower production of reservoirs. This study uses a stochastic conceptual snowmelt-runoff model to generate ... -
Graph-Theoretic Approach and Sound Engineering Principles for Design of District Metered Areas
(American Society of Civil Engineers, 2014)The design of district metered areas (DMAs) in existing water distribution networks, especially in urban areas, involves a high number of decision variables, and the effects of implementing them in districts have to be ... -
Water Resources Sustainability: Development of a Multiobjective Optimization Model
(American Society of Civil Engineers, 2014)This research investigates the application of multiobjective optimization (MO) modeling to the issue of water resources sustainability, from a water supply standpoint, with specific application to the Prescott Active ... -
Quantification of Water Savings due to Drought Restrictions in Water Demand Forecasting Models
(American Society of Civil Engineers, 2014)This paper presents a technique to quantify water savings due to implementation of water restrictions by adopting water restriction indexes as a continuous numerical predictor variable in regression analysis. The adopted ... -
Simulation and Optimization of a Constructed Wetland for Biomass Production and Nitrate Removal
(American Society of Civil Engineers, 2014)Nutrient-intensive agriculture involving nitrogen application rates exceeding crop requirements results in excessive loads in surface waters, contributing substantially to hypoxia in coastal ecosystems and violations of ... -
Robustness-Based Design of Water Distribution Systems
(American Society of Civil Engineers, 2014)Robustness is generally defined as an ability of a system to maintain its function under a defined set of disturbances. To introduce robustness to the water distribution systems (WDSs) design, chance constrained, or so-called ... -
Optimization of Water Distribution Systems Using Online Retrained Metamodels
(American Society of Civil Engineers, 2014)This paper proposes the use of online retrained metamodels for the optimization of water distribution system (WDS) design. In these metamodels, artificial neural networks (ANNs) are used to replace the full hydraulic and ... -
Optimal Location of PRVs and Turbines in Water Distribution Systems
(American Society of Civil Engineers, 2014)Pressure reducing valves (PRVs) are often used to manage pressure and reduce losses in water distribution systems (WDS). Different approaches are available in the literature on how to locate and set the PRVs in order to ... -
Simulation-Optimization Methodology for the Design of Outlet Control Structures for Ecological Detention Ponds
(American Society of Civil Engineers, 2014)This work presents a new paradigm for the design of stormwater detention basins. Through simulation and optimization, this work seeks to find the design of a detention basin outlet control structure that reduces the ... -
Nonlinear Reservoir Optimization Model with Stochastic Inflows: Case Study of Lake Tenkiller
(American Society of Civil Engineers, 2015)This study is primarily concerned with the planning and management of a multipurpose reservoir. An economic stochastic optimization model is developed and solved to maximize the net economic benefits derived from marketed ... -
Innovative Technologies for Storm-Water Management Programs in Small Urbanized Areas
(American Society of Civil Engineers, 2014)Small urbanized areas (UAs) as defined by the U.S. Census and the Environmental Protection Agency (EPA) have a population between 50,000 and 100,000, and a population density of at least 1,000 people per square mile. Under ... -
Application of Formal and Informal Bayesian Methods for Water Distribution Hydraulic Model Calibration
(American Society of Civil Engineers, 2014)Water distribution system model parameter calibration is an important step to obtain a representative system model, such that it may be applied to understand system operational performance, often in real time. However, few ... -
Flexible Water Distribution System Design under Future Demand Uncertainty
(American Society of Civil Engineers, 2015)In order to address the issue of water demand uncertainty due to the effect of climate change and urbanization in the design and management of water distribution systems (WDSs), a flexible methodology that combines sampling ... -
Power of Screening Models for Developing Flexible Design Strategies in Hydropower Projects: Case Study of Ethiopia
(American Society of Civil Engineers, 2014)Long-term price changes in water resources benefits may greatly affect a project’s value, however the traditional approach to river basin planning has not been able to take full account of these uncertainties. Additionally, ... -
Integrative Method for Quantifying Floodplain Habitat
(American Society of Civil Engineers, 2014)Restoring functional, self-sustaining floodplain habitats requires explicit consideration of the flow dynamics that once created healthy floodplain ecosystems. This paper describes a new method for quantifying the benefits ... -
Paleoclimate Scenarios to Inform Decision Making in Water Resource Management: Example from Southern California’s Inland Empire
(American Society of Civil Engineers, 2014)Southwestern United States paleoclimate reconstructions feature droughts that are longer and higher in magnitude than any water shortage during the twentieth century, and thus could aid water managers in planning for future ... -
Pipe Burst Risk State Assessment and Classification Based on Water Hammer Analysis for Water Supply Networks
(American Society of Civil Engineers, 2014)Hydraulic transients pose many risks to urban water distribution systems. The high pressure induced by a hydraulic transient can cause pipe bursts, the negative pressure can cause pipe collapses, cavitation can cause ... -
