Early Warning System
The Rock Hazard Rating System (RHRS) can help highway owners mitigate the risks of rock slope failure. This system helps owners determine which slopes are most hazardous and should be...
Yesterday's Data�Tomorrow
Before the advent of computer-aided design (CAD) and geographic information systems (GIS), keeping documentation for future usage was no problem. All an engineer had to do was make sure...
The New Perspective on I.T.
In the last few years engineering firms have stopped seeing information technology as a support system and started looking at it as an opportunity to create new series. Through Web sites,...
Site Seeing
Project-specific Web sites (called project extranets) are used to communicate project information in a fast, cost effective and efficient manner. These Web sites act as a project's...
Water, Water, Everywhere (Available in Geoenvironmental special issue only)
The discovery of extensive contamination just prior to construction of an underground library storage facility prompted engineers from the Minneapolis-based firms CNA Consulting Engineers...
Metal Building Systems: A New Look
The use of metal building systems in low-rise, non-residential construction under 150,000 square feet has grown from less than 50 percent in 1986 to almost 70 percent today. Such systems...
Participatory Engineering: Community Involvement to Maximize Benefits of Infrastructure Improvement in Vietnam
(No paper) Participatory engineering deals with the processes which link communities to the technological interventions which affect them. Examples of sustainable linkages abound in many...
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...
City of Phoenix Water System Water Plan: Beyond the Year 2000
(No paper) System demands with the City of Phoenix water system are accommodated by utilization of water supplied from several different sources distributed through an interconnected system....
Del Webb's Innovative Approach to Master-Planned Community Development
(No paper) The Del Webb Corporation is currently building a master planned development on the northern edge of Maricopa County. The development plan includes a water campus housing a water...
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...
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...
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...
