Selection of Sediment Transport Relations Part III: Numerical Ranking of Sediment Transport Relations
The emphasis of this paper is the methodology for the selection of sediment transport relations and is applicable for analysis of any sediment transport relation. However, to illustrate...
Reduction of Sediment Loads in DEC Streams
The U.S. Army Corps of Engineers, Demonstration Erosion Control (DEC) project is actively involved in the stabilization and restoration of many drastically disturbed incising streams in...
Field Measurements of Streambed Scour at Bridge Piers in Ohio
Field measurements made from 1989 to 1994 were evaluated to characterize pier scour at 21 bridge sites in Ohio. Pier scour was observed at sites in 45 of 47 real-time scour measurements....
How to Manage Floodwaves in the Dutch Meuse: Future Measures to Reduce the Inconvenience of Inundations
This study showed that in the Gravelmeuse the combination of nature development and reducing of inundation inconvenience is possible. In the framework of the obliged supply of a fixed...
Channel Scour Protection at Roadway Crossings
There are several forms of channel scour which may damage a bridge or culvert crossing over a natural or improved channel. Typical forms of scour include general degradation, local scour...
Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...
Synchronized Measurements of Bed-Shear Stress and Flow Velocity in Open Channels with Simulated Vegetation
Synchronized measurements of shear stresses at the bed and velocities both within and above a simulated plant canopy in an open-channel flow are presented. Traditional (hot-film sensors)...
A New Technique for Measuring Vegetation Density
Detennination of the discharge capacity of a vegetated channel or floodplain requires a reasonable estimate of a flow resistance coefficient; such as Manning'
Propeller Wash Induced Erosion at Quay Walls
The characteristics are examined of the sea bed erosion produced by the scouring action of a ship's propeller wash acting against a quay wall. The rate of development of erosion...
Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...
Scour Protection in Bottomless Culverts
This paper will describe the relative severity of scour anticipated to occur at bottomless culverts and will provide some design guidance for scour protection based on research referenced...
Study of Hydraulic Jump Lengths on Inclined Channel Beds
A hydraulic jump is generally used to dissipate kinetic energy of flow to protect man-made structures such as spillways, drop structures, and outlet works. It serves as a perfect location...
Rock Foundations
This manual provides technical criteria and guidance for the design of rock foundations for civil works or other similar large military structures. It provides a minimal standard to be...
Creeping Suspicion
High-capacity, epoxy-coated anchors were installed at Upper Occoquan Dam to increase the stability of the 70-foot-high concrete gravity dam and powerhouse under revised Probable Maximum...
Riddle of the Riverbed
The design of the Salt River Viaduct as part of the Red Mountain Freeway in Phoenix, Arizona, presented unique geotechnical problems. A cemented silty clay layer underneath the surface...
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...
Seismic Design Doubles Lateral Resistance (Available only in
A veterans hospital in Palo Alto, Calif. had to be built under severe design constraints. The seismic code for hospitals is among the most stringent of codes and this facility was sited...
Design of Sheet Pile Walls
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 15 From foundation exploration and testing procedures...
High Over Shanghai
In response to difficult design conditions, Shanghai's Jin Mao Tower's structural system harmoniously mixes building materials and strategically places them to...
Blast Wall Bravura
Since the 1988 disaster on the Piper Alpha platform in the North Sea, which claimed 165 lives, legislation in the United Kingdom has required the operators of offshore installations to...
