Reconstructing from Rubble
An architect has imagined a 3-D-printed solution to reuse rubble from war-torn Mosul, Iraq, to create crossings and urban farms across the Tigris River....
Crossing the Hollandsch Diep
The design/build team charged with creating an aesthetically pleasing bridge in the Netherlands for high-speed rail faced tough requirements, among them tight construction tolerances and...
Poetic Crossing
Named for Georgia's first national poet, Sidney Clopton Lanier, the new Sidney Lanier Bridge, spanning the Brunswick River in the city of Brunswick, is an elegant structure...
Carolina Crossing
The designers of a cable-stayed bridge across the Cooper River in South Carolina incorporated stringent seismic criteria to safeguard against potentially devasting earthquakes....
The Train Lane
With the elimination of more than 200 at-grate roadway crossings, the Alameda Corridor - $2.4-billion rail cargo expressway in Los Angeles - will carry 100 freight trains in and out of...
A Major Water Main Crossing of the Ohio River at Cincinnati
This presentation chronicles a major water main crossing of the Ohio River at Cincinnati. The project is of interest because it provides for the interstate sale of drinking water and technical...
FishXing 2.0 Software and Learning Systems for the Analysis of Fish Migration through Culverts
A brief explanation of the software FishXing....
Outstanding Civil Engineering Achievement Awards
Out of 27 nominations, the $9.8 million Cape Hatteras Light Station Relocation Project, which saved a national treasure along the North Carolina coastline and required extensive planning...
Rebuilding a Railroad Bridge
The Peck Movable Bridge and Bridgeport Viaduct is a four-track crossing in Connecticut that serves three rail lines. The 1904 bridge had deteriorated, causing a kink that forced trains...
Pipe Up
The East Bay Municipal Utility District (EBMUD) provides potable water for approximately 1.2 million people in San Francisco's East Bay area and is constructing seismic upgrades...
Channel Stability Assessment for Flood Control Projects
This manual provides assistance for determining potential channel instability and sedimentation effects in flood control projects. It is intended to facilitate consideration of the type...
Application of High-Resolution Schemes to Free Surface Flows in Irregular Channels
A 1-D flow model employing a high resolution scheme based on the Total Variation Diminishing concept is applied to non-prismatic channels of irregular cross-section. The hydraulic properties...
Grade Control Structures for Pipeline Crossings in the Arid Southwest
Pipeline crossings at streams, rivers, and washes are at risk due to bed and bank erosion in the river environment. Buried pipelines may be exposed in the channel bottom by scour of bed...
Simulation of Regional Ground-Water Flow on a Transboundary Flowline; Trans-Pecos, Texas and Chihuahua, Mexico
A two-dimensional, steady-state, cross-sectional model was used to evaluate boundary conditions, residence times, and potential transboundary movement along a 28 mi (45 km) flowline between...
Design and Construction of the Santa Ana River Wash Crossing of the Inland Feeder
The Inland Feeder Pipeline passes beneath the Santa Ana River in Southern California. The flood plain of the river provides the habitat for two endangered species and to avoid surface...
Design Alternatives for Protection of the Santa Ana River Interceptor Sewer
The Santa Ana River Interceptor Sewer (SARIS) line buried within the floodplain of the Santa Aria River is being threatened by long term degradation of the river bed at the pipeline crossings,...
Optimal Sizing of Width- and Depth-Constrained Trapezoidal Channels
Open-channels are often designed based on the assumption of uniform flow and normal depth. If a channel is to be lined with a nonerodible material, the dimensions of the channel can be...
