Use of Economic Optimization to Evaluate New Facilities
(No paper) The confluence of the Sacramento and San Joaquin rivers and the San Francisco Bay forms the largest estuary on the West Coast. Known as the Bay-Delta, the region supplies drinking...
Use of Economic Optimization to Assess the Value of Water Marketing
(No paper) There is an increasing interest and implementation of water markets as an allocation mechanism for water in the Western U.S. However, the importance of the timing and location...
Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...
Stepwise Flood Routing for Gated Reservoirs and Conjunctive Optimization of Hydroelectricity Income with Flood Losses
A six-stage operation policy for routing of flood hydrographs of return periods from 1.01 year up to the Probable Maximum Flood (PMF) for dams having gated spillways is suggested. The...
Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...
Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...
Cost-Effective Risk-Based In Situ Bioremediation Design
(No paper) Risk-based corrective action (RBCA) is rapidly becoming the method of choice for remediating contaminated groundwater sites, particularly for contaminants such as petroleum...
Watershed and Reservoir Response Models for the Occoquan Reservoir
(No paper) The Occoquan Reservoir serves as a primary water supply for over 800,000 Virginians in the Washington (DC) Metropolitan area. The Occoquan Watershed is approximately 560 square...
A Decision Support System for Assisting Operation of Artificial Recharge Systems
A series of simulation and optimization models analyzing artificial recharge systems have been linked within a decision support system (DSS) with a graphical interface. The model includes...
Integration of SWMM and ARCVIEW GIS for Interactive Decision Support
(No paper) This paper covers the integration of the EPA SWMM runoff model and ESRI's ArcView GIS for utilization by the City of Phoenix for decision support concerning land use changes...
Interface and Data Management for Large Scale Optimization Models
(No paper) This paper presents ideas regarding how different groups of data can be stored and utilized, especially in the context of water resource policy discussions involving different...
Friction Factor Choice in Hydraulic Simulation Models: Does It Matter?
(no paper) To model water distribution systems using computer hydraulic simulation, a user is required to select a form of head loss-flow relationship for each pipe in the network. The...
Evaluation of Two-Species Model for Chlorine Decay and THM Formation under Rechlorination Conditions
(No paper) Typically, chlorine decay has been described by a first-order decay model. The first-order model, however, has two drawbacks: 1) the reactive species within the water is assumed...
Sensitivity of Stormwater Conveyance System Cost to Design Recurrence Interval
(No paper) The cost of a piped and/or swaled stormwater system is determined principally by the storm recurrence interval (e.g., 5-year design storm) used to design it. That is, the present...
Adjustments to Short-Term Hydrologic Forecasts for Conceptual Models of Hydrologic Processes
(No paper) Real-time forecasting of streamflows is amorphous and multi-dimensional. Weather forecasts, which are synonymous in popular culture with uncertainty, are just one component...
A Leadtime Driven Flood Warning Response Plan Design
(No paper) The paper examines the optimal combination of predictive and detective capabilities in the development of the Wickenburg Flood Response Plan and extrapolates those findings...
Long-Term Streamflow Forecasting
(No paper) Technology is creating major impacts on water management decisions dynamics. Today emerging technologies, such as satellite rely of hydrological and meteorological data, improvement...
Water Resource Systems and Modeling of the Lower Virgin River Using EXCEL
(No paper) The first objective of this study was to determine the availability of water at the confluence of the Halfway Wash and the Virgin River and to simulate the diversion of river...
