Use of Optimization Techniques to Evaluate Ground-Water Management Strategies in the Central and West Coast Basins, Los Angeles County, California
The U.S. Geological Survey and the Water Replenishment District of Southern California are engaged in a cooperative study of the geohydrology, geochemistry, and ground-water management...

A Statewide Economic Optimization Model for California II: Model and Results
(No paper) Traditionally simulation models have been used for multi-reservoir operation studies. More recently deterministic optimization models have been used to identify promising alternatives...

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...

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...

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...

(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...

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...

Environmental Restoration and Management of the Tres Rios Demonstration Constructed Wetland Project: Mosquito Monitoring, Control and Management Efforts
(No paper) The Tres Rios Demonstration Constructed Wetland Project in Phoenix, Arizona, is providing valuable information on the role of constructed wetlands in ecosystem restoration,...

Practical Applications of Gage-Adjusted Radar?Rainfall Estimates
(no paper) It is radar's estimates of rainfall at a specific location that tends to disappoint. On the other hand, the strength of rain gage observations is in estimating rainfall at a...

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...

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...
