The Costs and Benefits of Dam Removal on the Elwha River
The Elwha River is located on the Olympic Peninsula in the State of Washington. In the early 1900s two hydroelectric dams were built on the Elwha River. Construction of Glines Canyon and...
Design of a Floodplain Road Crossing Using Two Dimensional Modeling
A two dimensional hydraulic model (FESWMS) is prepared to evaluate flood conditions for the Canal Parkway Project, located in western Maryland. The parkway includes a 32 meter bridge replacement...
Evaluating Strategies to Manage Seawater Intrusion
A simulation-optimization model has been developed to evaluate strategies for managing seawater intrusion in the Oxnard Plain, Ventura County, California; however, this model addresses...
Emulation of DWRDSM using Artificial Neural Networks and Estimation of Sacramento River Flow from Salinity
Artificial Neural Networks (ANNs) are widely used and well-suited for multiple non-linear regression. Department of Water Resources Delta Simulation Model (DWRDSM) is a computer model...
Analyzing Water Balances and Ranking Maryland's Watersheds Related to Growth, Development and Loss of Habitat
One hundred thirty three watersheds comprising the entire state were analyzed for surface and ground water balance. Census population figures (1990) were allocated to the watersheds. Population...
Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...
Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...
Accessible Information
As the amount of data relating to U.S. environmental policy grows, geographic information systems and advanced visualization system technology are being applied extensively to site investigations...
New Orleans Rolls the Dice (Available only in
To compete with the gambling meccas of Las Vegas and Atlantic City, New Orleans recently took a gamble by erecting the world's largest casino building. With the structure...

Chicago's Micropile Debut
On a tight, urban site around Chicago's historic Orchestra Hall, engineers used high-capacity micropiles as an alternative to hand-dug caissons. On a $104 million project...
Milwaukee's Ozone Upgrade
After the 1993 outbreak of illness caused by Cryptosporidium in Milwaukee, the city moved forward on an $89 million upgrade of its treatment facilities with ozone filtration, the only...
Who Springs for Water?
Many questions have been raised about the future of water quality and maintenance. The Rocky Mountain Institute has created a report with four scenarios, each based on whether the government...
Honolulu's Street Relief
Engineers faced the daunting prospect of burying a new relief sewer under a busy Honolulu highway with trench-cut methods. The contractor suggested microtunneling, but the coral reef formations...
An Interception by Boston
Engineers in Boston were recently challenged to design a rehabilitation and replacement for sections of the 60-year-old St. James Avenue sewer system. Approximately 20,000 vehicles per...
For Sure Shores
Fighting a long history of beach-destroying structures and man-made inlets, coastal engineers are finding that the answer to beach erosion lies in a deeper understanding of its dynamic...
