Around the Bend
An architecture firm envisions an inverted U-shaped tower in New York City that would outstrip the height of current megatall structures and replace it with length....
Performance Limits for Deepwater Pipelines
This paper highlights the differences between onshore and offshore pipeline design. It then summarizes the results of combined external pressure, tension, and bending testing on full scale...
Mechanisms Controlling the Permeability of Clays
Coefficients of permeability, calculated using Terzaghi's theory of one-dimensional consolidation, are reported for smectite, illite, and kaolinite, in water, methyl and ethyl...
Design of Urban Stormwater Controls
Fully updated to address the paradigm shift in the way stormwater is viewed and managed, Design of Urban Stormwater Controls focuses on consolidating technologies to foster a convergence...
Changing Course
Guidelines governing areas subject to 100-year flood consider the expected vertical elevation of floodwaters but overlook the possibility that a river channel may move laterally. A recent...
Headcut Analysis for Off-Channel Gravel Pits in Arid Environments
The study focuses on a large gravel pit located adjacent to the Santa Cruz River between the confluences with the Rillito and Canada del Oro rivers in Tucson, Arizona. These gravel pits...
Advancing Under London
Bored tunnels account for more than 20 percent of the Channel Tunnel Rail Link, the high-speed rail line that will connect the Channel Tunnel with London upon its completion in 2007. In...
Changing Channels
When the strict design parameters of a correctional facility in remote Pennsylvania meant blocking a headwater stream, a team of environmental engineers rerouted the waterway 400 ft (122...

Stochastic and Deterministic Origins of Aquatic and Riparian Habitats
Development of aquatic and riparian habitats involves interactions among large numbers of climatic, geomorphic, hydrologic, and vegetative processes over time. A major component of these...
Using Tracer Response Curves to Quantify Hydraulic and Channel Complexity of Prairie Creek, Northwestern California: Implications for Over Wintering Habitat for Juvenile Coho Salmon
This study measured and compared aspects of channel structural complexity with hydraulic complexity at a range of flows including winter storm flows. Five 200-meter reaches containing...
Investigation of Flood Protection from Alluvial Fan Flows and Minimizing Impacts to a Sensitive Habitat Preserve: Whitewater River Basin, Coachella Valley, California
The study describes and evaluates (1) the baseline conditions to hydrology, hydraulics, wind transport of sand, sediment transport by fluvial process, the environment, economics, and (2)...
Design Considerations for the North Railroad Alluvial Fan Levee System in Boulder City, Nevada
This paper presents a drainage study for a flood control levee system in Boulder City, Nevada. This levee system is located below an alluvial fan watershed and was proposed to protect...
A GIS Model for Assessing the Impact of Increased Channel Discharges on Hydraulic Geometry
A GIS model is being developed that can be used to assess the impact of increased channel discharges on the hydraulic geometry of streams in the Powder River (structural) Basin in northeast...
Dual Benefits
When the Port of Houston needed to be dredged to accommodate larger commercial vessels, engineers decided to put the dredged material to use to create wetlands and islands that will serve...
Adaptive Management for Atchafalaya Basin, LA Water Management Units
The Buffalo Cove Water Management Unit is a pilot unit in the Atchafalaya Basin that has been implemented as part of the Atchafalaya Basin Floodway System project. The pilot unit goals...
New Navigation Channel
Among the facilities needed to accommodate Pier 400 at the Port of Los Angeles (POLA) was a new navigation channel to handle the increased container and liquid bulk traffic that the port...
Phase II Evaluation Findings
The Segmental Concrete Channel Bridge System
Prepared by the Highway Innovative Technology Evaluation Center (HITEC), a CERF Innovation Center. This report represents the second component of the...
Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...
Ground-Water Quality in Basins with Minimal Urban Development, Arizona
Ground-water quality data (191796) from 2,013 wells in 16 alluvial basins that have minimal urban development, were used to determine the effect of nonurban factors on ground-water quality...
