A GIS Based Synthetic Watershed Sediment Routing Model
For most watersheds, extensive water quality data are not available. Land use, topographic, edaphic and meteorological information is generally available; but without extensive water quality...
We Need to Integrate Water Transportation and Environmental Protection Planning and Policy
There are important connections between environmental natural resources and transportation policies and programs. Such links between air quality and transportation have been recognized...
A Multi-objective Criteria Analysis for Alternative Route Planning
A multi-objective criteria analysis was used to identify a proposed rail spur route with the optimal combination of low environmental impact, favorable engineering characteristics and...
Use of Contaminant Mobility and Transport Parameters to Determine Water Testing Protocol
By 1994, EPA plans to regulate 83 contaminants in public water supplies. For rural communities and individuals who are not classified as public systems, the cost to monitor all 83 contaminants...
BRASS Modeling of Lo?za Reservoir, Puerto Rico, for Sediment Management Operations
Loiza reservoir, the principal water supply for metropolitan San Juan, delivers 3.5 m3/s (80 mgd) to the Sergio Cuevas filter plant. Sedimentation...

Overhead and Profit on Change Orders
Have you ever wondered how many change orders it took to build the Egyptian pyramids or the Great Wall of China? The concepts of overhead, profit, and change orders have been around for...
Transportation Lifeline Losses in Large Eastern Earthquakes
In December 1991 Applied Technology Council (ATC) and its subcontractor, EQE Inc., completed a 2-year Federal Emergency Management Agency-sponsored study to assess the seismic vulnerability...
Ports '92
This is a collection of the technical papers presented at the Ports '92 Conference held in July 1992 in Seattle, Washington. Initiated in 1977, this Conference is the sixth...
Rehabbing the Rails
In 1984, during a routine bridge inspection, a worker detected deterioration under the south abutment of a bridge that carried the main line of Philadelphia's commuter railroad....
HOV Lessons
As traffic congestion worsens, transportation planners are struggling to squeeze out every last bit of available roadway capacity. High-occupancy vehicle lanes are one solution, but aren't...
Use of X-Ray Computed Tomography in the Study of Marine Sediments
X-ray computed tomography (CT scanning) is primarily a medical imaging technique. When applied to marine sediments, it responds predominately to the spatial density distribution within...
Old Problems and New Challenges in Marine Geotechnical Engineering
The discipline of marine geotechnical engineering originated nearly five decades ago, primarily as a result of the offshore oil and gas industry. As this industry moved into deeper waters,...
The Greening of Greens
Until recently, most consulting engineers thought golf courses were fun to design, good for the portfolio, but not worthy of much serious thought. Environmental issues and competing uses...
