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...

Potential Effects of San Mining and Debris Basins on Coastal Sediment Supply in Los Angeles County
The potential sediment supply to the coast in Los Angeles has been heavily impacted by human activity. In the context of rational management of beaches as a resource, it is fundamental...

Damn Sand Rights: Removing Rindge and Matilija Dams
Two dams built in the 1920's and 1940's within southern California coastal drainages have reached the end of their useful lives, and their decommissioning and removal is being actively...

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...

Subirrigation: Water Table Management
Water table management (subirrigation) is accomplished by controlling the water table, usually through a subsurface drainage system. The crop is subirrigated with water being furnished...

Wetlands Treat Mine Runoff
Engineers were asked to design a treatment system for the severely acidic drainage from the Mike Horse and Anaconda metals mines in Montana. Challenges included the mountainous terrain,...

Cold Climate Solution
To reduce turbidity in sedimentation-basin discharge, Anchorage, Alaska, is experimenting with constructed wetlands to augment storm-water discharge treatment from several storm-drain...

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...

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...

A Risk-Based Approach to Subsurface NORM Disposal
(No paper) Naturally occurring radioactive materials (NORM) has become an environmental concern for the petroleum industry. NORM scales results when naturally occurring radium co-precipitates...

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...

Sensitivity of Stormwater Conveyance System Cost to Design Recurrence Interval
(No paper) The cost of a piped and/or swaled stormwater system is determined principally by the storm recurrence interval (e.g., 5-year design storm) used to design it. That is, the present...

The Arch Bridge Mystery
For some years, concrete from the Manayunk Bridge�a long-idle, spandrel-arch railroad bridge in Philadelphia�had been spalling toward the streets and river below. While a system of nets...

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....

Preparing for Pier A
Earthquakes, oil wells, contamination and unstable soil were among the challenges engineers faced as they prepared a site at California's port of Long Beach for the Pier A...

Filtration and Drainage in Geotechnical/Geoenvironmental Engineering
This proceedings, Filtration and Drainage in Geotechnical/Geoenvironmental Engineering, is a collection of papers presented at the sessions...

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...

Wetland Wonder
Pinellas County and the Southwest Florida Water Management District's Surface Water Improvement and Management (SWIM) Department jointly retrofitted an urban drainage basin...

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...

Newport News: Brackish Water Gets Fresh
Rapid growth was straining freshwater supplies in Newport News, Virginia. Studies showed Newport News Waterworks that they could be facing a 30 mgd deficit by 2040 and ran a 50% chance...
