A Brief History of Jet Grouting in the Last 50 Years: The Story of Its Evolution
Jet grouting, a grouting soil improvement construction technique, was first developed in Japan in the 1960s and 1970s, and then introduced in Europe a few years later in the form of a proposal for soil...

Simulating Radionuclide Transport Away from an Underground Nuclear Test: Linking Non-Isothermal Flow and Mechanistic Reactive Transport
The low-yield (0.75 kiloton) Cambric underground nuclear test situated in alluvium below the water table offers unique perspectives on radionuclide transport in groundwater. The Cambric...

Permits, Surface Water/Groundwater Baseline Sampling, and Analysis of Dewey-Burdock In Situ Uranium Project in Fall River County, South Dakota
Powertech Uranium Corporation has proposed to conduct in situ mining within a uranium enriched ore deposit on the proposed permit area known as the Dewey-Burdock project. The project is...

Monitoring and Quantifying Rate-Limited Mass Transfer Using Geoelectrical Measurements
Non-Fickian solute-transport behavior has been observed at research and aquifer remediationsites in diverse geologic settings. Anomalous behavior such as concentration rebound, long breakthrough...

Refrigerated Foundations
Refrigeration systems used to cool foundations on frozen ground can be classified as either active or passive, depending on whether external energy is used to power the systems. If pumps,...

Hurricane Protection System
This chapter discusses hurricane protection systems. Topics include standard project hurricane, levees and floodwalls, datums and elevations, and interior drainage and pump stations....

Direct Causes of the Catastrophe
This chapter examines direct physical causes of the hurricane protection system failures, including soil strength assessments and pumping station limitations....

Simulation/Optimization Modeling Post-Audits
S/O models have long been used to compute optimal strategies for user-specified optimization problems. It is useful to provide a retrospective of two S/O modeling applications, and how...

Tapping the Desert
As part of an effort to augment the limited supply of freshwater in El Paso, Texas, engineers and planners are eyeing a new source: desalinated water pumped from beneath the desert floor....

Closing the Loop
By constructing an enormous pipeline system and a new pumping station, the city of Irving will bring a new supply of water to the Dallas-Fort Worth region and improve the reliability of...

Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...

Water for Ahwatukee
Scheduled for completion in August, the South Mountain Water Facilities pipeline will increase drinking water capacity to the community of Ahwatukee Foothills, a rapidly growing south...

Hydrogeology and Irrigated Agriculture
A review of drainage problems and groundwater processes on the west side of the San Joaquin Valley (SJV), California, provides useful perspectives on hydrogeology and irrigated agriculture....

Sedimental Journey
A numerical shoreline evolution model was used to examine the shoreline changes associated with the release of 2.3 million m� of beach-quality sediment from behind Matilija Dam in Ventura...

Returning to the Source
One hundred years ago, Las Vegas was a dry, dusty dot on the map with a population of only 100. The city grew up to become perhaps the gambling capital of the world, and more recently...

A Natural Approach
Before the Comprehensive Everglades Restoration Plan began, the Florida legislature established the Everglades Construction Project (ECP), a $708-million, 10-year program now being implemented...

Coming to the Surface
In the past few years, the coastal areas of the Gulf of Mexico and much of Texas have experienced less than normal rainfall and record water demands. During this period, average daily...

Big Screen Debut
The Glenn-Colusa Irrigation District (GCID) encompasses nearly 150,000 acres (60,700 ha) of prime agricultural land in California's Sacramento Valley, generally considered...

Water In, Water Out
Moving water into and out of the Eastside Reservoir, which will be the largest body of freshwater in southern California, requires some of the largest pumping and water conveyance systems...

Mississippi Diversion
The $103-million Davis Pond freshwater diversion project in coastal Louisiana will divert up to 10,650 cfs (300 m�/s) of Mississippi River water to the Barataria Bay Estuary through four...
