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...
Surface Irrigation
Surface irrigation refers to a large group of irrigation methods in which water is distributed by gravity over the surface of the field. Water is typically introduced at the high point...
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...
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...
A Statistical Approach to Modeling Groundwater Hydrology in a Constructed Wetland on the Atlantic Coastal Plain, Delaware
The design of wetlands based on groundwater as the principal source of hydrology pose uncertainties in areas where erratic seasonal groundwater fluctuations exist. Under these conditions,...
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....
