Economic Valuation of Agricultural Water Use for Large-Scale Modeling
(No paper) A state-wide irrigated agricultural production model has been developed for California. The model is an extension of the Central Valley Production (CVP) Model that was most...
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...
The Evolution of Florida Water Management
(No paper) The State of Florida has always been very cautious to protect it's natural resources which is the cornerstone of the State's economy. The availability to vast quantities of...
Robust Techniques for Extension of Streamflow Records
Longer hydrological records are required for the planning of water resource systems. Sensitivity of a system is studied under various scenarios of hydrological inputs to understand its...
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...
Urban Runoff Toxicity
Toxicity is controlled by the magnitude/concentration of the contaminant produced in an exposure, the duration of the exposure, and the frequency with which exposures are repeated. When...
Resolving the Water Wars: The Compacts Between Alabama, Florida, and Georgia
(No paper) Several water supply proposals on behalf of Georgia have caused a water rights ?war? which pits Alabama and Florida against Georgia in the Apalachicola, Chattahoochee, and Flint...
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...
A Review of Established Water Markets and Quasi-Water Markets
This presentation provides a review of established institutional mechanisms which regulate the transfer of water withdrawal rights. Each method of water rights transfer is evaluated in...
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...
A GIS-Based Interactive Decision Making Tool for Watershed Management
(No paper) BASINS?Better Assessment Science Integrating Point and Nonpoint Sources, a geographical information system- (GIS-) based tool developed and released by the US EPA, provides...
Traditional Engineering Takes a Turn for the Future Decommissioning Dams and Restoring Ecological Integrity
(No paper) This paper will address the emerging shift evaluating the true value of dams and the importance of including the costs of the initial construction and investments required for...
Impacts of CSO Swirl Concentrator on Dissolved Oxygen Concentrations in the Anacostia River
Purpose: To assess impacts of the CSO control, two continuous monitoring stations were located upstream and downstream from the CSO outfall. The monitors recorded dissolved oxygen (DO),...
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...
Determination of Flood Frequency as a Function of Mitigation Expenditure
(No paper) This paper describes an approach to the determination of flood frequency as a function of moneys that could be spent to address a road flooding problem caused by runoff from...
