Application of the Texas A&M University (TAMU) Dredging Cost Model to Long Distance Transport
To develop intelligent decisions about moving sediment long distances to the coast from dams, the cost becomes a major factor. The cost will be a function of many factors including cleaning...
Environmentally Friendly Transport of Reservoir Sediment for Beach Nourishment with EDDY Pump
Sand impounded behind hydroelectric, flood-control and debris dams not only diminishes the intended function of the reservoir, but also starves downstream coastline by denying natural...
Coastal Benefits and Impacts of Dismantling Matilija Dam
A numerical shoreline evolution model was used to examine the shoreline changes associated with the release of 2.3 million cubic meters of beach quality sediment from behind Matilija Dam....
The New Orleans Network
Though Seattle and Portland are the cities usually associated with high rainfall, the New Orleans metropolitan area averages 58 in. (1,473 mm) of rainfall each year�more than any other...
Application of Linear Programming Techniques to Optimize Groundwater Withdrawals for a Pump and Treat System at Aberdeen Proving Ground, Maryland
The U.S. Army disposed chemical agents, laboratory materials, and unexploded ordnance at the O-Field landfill from before World War II until at least the 1950s. Soil, ground water, surface...
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...
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...
Optimization of the Aquifer Remediation Costs and Design with Pulsed Pumping
(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce...
Theoretical and Empirical Implications of Increasing Block Rates
(No paper) The U.S. Army disposed chemical agents, laboratory materials, and unexploded ordnance at the O-Field landfill from before World War II until at least the 1950s. Soil, ground...
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...
A Tale of Two Bids
In early 1992, the Escambia County Utilities Authority determined that its 2 mgd Avondale Wastewater Treatment Plant should be expanded to 8 mgd to meet the growing needs of the Pensacola,...
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...
Cliffside Correction
Construction of a 10 km sewer collector in Valpara�so, Chile, came to a halt due to construction difficulties experienced during pipe jacking operations. Analysis revealed not only construction...
Design of Municipal Wastewater Treatment Plants
This revised manual, updated from the previous edition, aims to be the principal reference of contemporary practice for the design of municipal wastewater treatment plants. The manual...
Sludge's Re-Treat
The Shreveport, La., water treatment plant was losing up to 25% of the water it pumped into filter backwashing and sludge. Demopulos & Ferguson Associates (DFA), Shreveport, designed...
Tunneling Against Time (Available only in the Geoenvironmental Special Issue)
The phenomenal growth of Las Vegas has prompted nearly $1 billion worth of water-supply projects. A $33 million tunnel scheme�a critical element of the new construction�is on pace. The...
Multiplicity (Available only in the Geoenvironmental Special Issue)
When it comes to tracking groundwater contaminant plumes, single completion monitoring wells are the standard choice, but they aren't the only one. After four years of trying...
Pumped-Up Pumping Stations
The Washington Suburban Sanitary Commission, a public utility serving Prince Georges County and Montgomery County, Md., publishes a design guide (DG-04) to help outside consultants meet...

A Multiperiod Approach for the Solution of Groundwater Management Problems using the Outer Approximation Method
In a previous work the Outer Approximation method was presented (Karatzas and Pinder, 1993 and 1996) for the solution of groundwater management problems where the selected pumping rates...
