Proposed Smart Market Design for Sediment Discharge
(American Society of Civil Engineers, 2013)Sediment discharge from erosion, urban runoff, and construction can cause environmental degradation. Governments try to regulate sediment, but the regulatory approach is costly to land owners. In principle, a market-based ... -
Optimal Design of Groundwater-Quality Sampling Networks with Three-Dimensional Selection of Sampling Locations Using an Ensemble Smoother
(American Society of Civil Engineers, 2013)In groundwater-quality monitoring it is important to consider that groundwater-contaminant concentration can vary vertically. To find the actual concentration of contaminants in a groundwater plume, it may be necessary to ... -
Box-Constrained Optimization Methodology and Its Application for a Water Supply System Model
(American Society of Civil Engineers, 2012)This study introduces a new search method for box-constrained optimization problems called the search method for box optimization (SMBO). SMBO is a population heuristic-based search methodology that solves global optimization ... -
Optimization of Well Field Operation: Case Study of Søndersø Waterworks, Denmark
(American Society of Civil Engineers, 2013)An integrated hydrological well field model (WELLNES) that predicts the water level and energy consumption in the production wells of a waterworks is used to optimize the management of a waterworks with the speed of the ... -
Short-Term Reservoir Storage Frequency Relationships
(American Society of Civil Engineers, 2012)The water rights analysis package (WRAP) is a generalized river/reservoir system simulation model that is routinely applied in Texas in regional and statewide planning studies and administration of the water right permit ... -
New Integrated Condition-Assessment Model for Combined Storm-Sewer Systems
(American Society of Civil Engineers, 2013)Optimal assessment of the overall state of the degradation affecting sewer systems requires consideration of both the hydraulic and the structural aspects. This work identifies a set of 15 factors—pertaining to both ... -
Field Studies and Modeling Exploring Mean and Maximum Water Age Association to Water Quality in a Drinking Water Distribution Network
(American Society of Civil Engineers, 2012)This paper presents the findings of an investigation into predicted/modeled water age and the associated quality characteristics within a UK drinking water distribution network to determine if there is a discernable link. ... -
Bayesian Update Method for Contaminant Source Characterization in Water Distribution Systems
(American Society of Civil Engineers, 2013)Bayesian analysis has application to probabilistic source characterization in water distribution systems. A new implementation of Markov-chain Monte Carlo (MCMC) for this problem is described. The solution addresses the ... -
Multiobjective Portfolio Analysis of Dam Removals Addressing Dam Safety, Fish Populations, and Cost
(American Society of Civil Engineers, 2013)Decisions concerning dam removal or retention are challenging because they involve tradeoffs, diverse stakeholders, and increasing public safety concerns. A multiobjective portfolio optimization approach, implemented as ... -
Integrated Planning of Land Use and Water Allocation on a Watershed Scale Considering Social and Water Quality Issues
(American Society of Civil Engineers, 2012)Sustainable development in river basins depends on sound management of land use and water allocation policies. Integrated water resources management (IWRM) is considered a path to bring many elements within the development ... -
Seasonal Water Allocation: Dealing with Hydrologic Variability in the Context of a Water Rights System
(American Society of Civil Engineers, 2013)In China, the allocation of water rights in river basins is customarily determined by annual mean volumes of water resources. However, seasonal variability of water availability should be considered for an effective and ... -
Identifying Cultural Flow Preferences: Kakaunui River Case Study
(American Society of Civil Engineers, 2012)The course of settlement, development, and economies within nations has long been deeply affected by the availability of water. In a New Zealand context, -
Impacts of Climate Change on Irrigated Agriculture in the Maipo Basin, Chile: Reliability of Water Rights and Changes in the Demand for Irrigation
(American Society of Civil Engineers, 2012)Agricultural regions located in snowmelt-dominated Mediterranean climate basins have been identified as being highly vulnerable to the impacts of climate change. The Maipo basin in central Chile is one such region. Projections ... -
Representing Energy Price Variability in Long- and Medium-Term Hydropower Optimization
(American Society of Civil Engineers, 2012)Representing peak and off-peak energy prices is often difficult in hydropower modeling because the time scale of price variability (hours or less) is much shorter than that needed for many operations planning models (days ... -
Finding Least-Cost Pump Schedules for Reservoir Filling with a Variable Speed Pump
(American Society of Civil Engineers, 2012)This paper presents a simple and straightforward technique to solve the problem of least-cost reservoir filling with the help of a variable speed pump in the case of a highly simplified hydraulic system. Although artificial ... -
Effect of Data Collection on the Estimation of Wall Reaction Coefficients for Water Distribution Models
(American Society of Civil Engineers, 2012)During a model calibration process, errors in field measurements propagate to uncertainties in model parameter estimates and model predictions. This paper presents a means to quantify that effect in a water distribution ... -
Extreme Impact Contamination Events Sampling for Real-Sized Water Distribution Systems
(American Society of Civil Engineers, 2012)Contamination warning systems are being designed to protect water distribution systems against deliberate contamination intrusions. To design a contamination warning system, contamination intrusion events need to be selected. ... -
Role of Modeling Uncertainty in the Estimation of Climate and Socioeconomic Impact on River Water Quality
(American Society of Civil Engineers, 2012)Climate is one of the most important factors leading to changes in the hydrologic and environmental characteristics of river basins. When considering water quality, the natural factors should be weighed against anthropogenic ... -
