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...
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...
Title Transfer of U.S. Bureau of Reclamation Projects: Fact or Fiction
(No paper) The U.S. Bureau of Reclamation (Reclamation) has constructed hundreds of water storage and delivery projects throughout the 17 western United States. These projects vary in...
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...
Underground Storage and Recovery: A Powerful Tool for the Management of the Limited Water Resources of the Phoenix Metropolitan Area
(No paper) The availability of imported Colorado River water to the Phoenix area in 1986 prompted the need for storage of the unused portion of each municipality's contracted allocation....
Putting Nature First
From salamander tunnels to hotels for red-legged frog, the $450 million Los Vaqueros dam and reservoir project in northern California put environmental concerns first in its planning and...
Geo-Engineering for Underground Facilities
The papers collected in this proceedings
When the Levee Inflates
Rubber dams�long, flexible tubes, anchored to a concrete base and abutments and inflated with air or water�have been used since the 1950s, but installations have risen as technology has...
Interest in Deposits (available only in Geoenvironmental Special Issue)
Sediment accumulating in reservoirs worldwide is gradually reducing storage capacity, posing a long-term threat to supplies of drinking and irrigation water. The buildups also highlight...
Out of Sight, Out of Time
A 10-year grace period for complying with an EPA regulation mandating that all underground storage tanks have spill, overfill and corrosion protection runs out on December 22, 1998. Hundreds...
Pump-and-Treat Rescue
The pump-and-treat method of remediation has been regarded for years as unsuccessful and untrustworthy. But a recent project in Chicago showed that in conjunction with horizontal wells...
Nothing Wasted
Anoxic gas flotation (AGF), a patented system for anaerobic digestion of organic slurry waste, can recover as much as 85% of the phosphorus and 23% of the nitrogen in slurry waste, while...
The San Francisco Connection
An underground switchyard and storage facility for San Francisco's Municipal Railway challenged the limits of both cut-and-cover and tunneling in loose soil. The project was...
Putting Wetlands to Work
Wetlands, whether natural or engineered, have enormous potential to clean up wastewater, but in the past, the public called on civil engineers to drain wetlands en masse as a public benefit....
Oil in the Soil
An oil well blowout in northern Italy contaminated about 1,500 ha of agricultural land primarily used to cultivate rice. The cleanup team decided to use bioremediation techniques because...
Everything Old Is New Again
Chicago's elevated Green Line, which connects Chicago's south and west sides with the downtown loop, has recently gone through an overhaul, getting new tracks,...
For Whom the Bugs Toil
Bioventing is soil ventilation intended to enhance the biodegradation of petroleum hydrocarbon contaminants in soils by providing a supply of oxygen. Soil microbes are capable of consuming...
In Situ Remediation of the Geoenvironment
The progress in the development and implementation of techniques for the remediation of contaminated soil and ground water has been and continues to be rapid. These proceedings focus on...
