Riprap Stability Results from Large Test Channel
Velocity data from a large test channel were used to determine the distribution of depth-averaged velocity and shear stress on the side slope of both straight and curved channels. From...
Minimizing Erosion Damage to Embankments, Spillways, and Channels With Articulated Concrete Block Revetment Systems
The results of a multi-year applied research and testing program, focusing on the hydraulic performance of various types of erosion control products and revetment systems in steep-slope...
Designing in Circles
Round buildings are a popular�but sometimes expensively perceived�design choice. With careful engineering and planning, they can offer a creative, cost-competitive option. They add another...
Orchestral Maneuvers
Symphony Towers is an H-shaped superstructure that straddles Symphony Hall in downtown San Diego. The $143 million project is a 34-story office building to the south of the hall and a...
Friction Slope Computation for Mathematical Models
The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods...
Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...
Bank Erosion: A Review of British Research
The paper summarizes recent contributions from British geomorphologists and hydrologists. This includes field measurements of processes, modeling of corrasion and mass failure, interactions...
Deposition at a New Dam Near Mount St. Helens
A sediment retention structure (SRS) is being constructed on the North Fork Toutle River in the state of Washington to trap sediments eroding off the 1980 Mount St. Helens debris avalanche....
High-Rise Embankments
Embankments reinforced with geosynthetic materials are being built at increasing heights. Any wall over 20 ft is still generally considered high, but embankments of 40 ft with near vertical...
Tunnel Maintenance Operations
Maintenance considerations during both the design and operational phases are very important to good tunnel maintenance. The use of proper materials able to withstand the rigorous environment...
Probabilistic Slope Stability?Case Study
The stability of a slope depends upon highly variable conditions of varying degrees of importance. Probability theory is used herein to assess the relative importance of the soil parameters...
Probabilistic Model for Stability of Slopes
Presented herein is a probabilistic model based on derived distributions to predict shear strength of soils and the safety factor of slopes considering uncertain properties of soil, namely:...
A Probabilistic 3-D Short-Term Slope Stability Model
A probabilistic model to analyze the three-dimensional stability of earth slopes under short-term conditions is presented. An actual failure case is studied to show the implementation...
Rock Armouring to Unconventional Breakwaters: The Design Implications for Rock Durability
This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armored slopes. The derivation and use of a suite of engineering tests for...
The Heavy Duty Geogrid Wall
The geogrid reinforced soil retaining wall was a key component in reconstructing a small hydroelectric plant situated at the center of Cascade Dam in Michigan. It was necessary that the...
Arctic Coastal Processes and Slope Protection Design
Cold regions present special challenges for civil engineers. The papers in this book address arctic coastal processes and slope protection design. The first part of the book focuses on...
Snow-Melt Triggered Debris Flows Affecting Utah's Megalopolis
During the abnormally wet years of 1983 and 1984, debris flows were triggered late in spring on the west flank of the Wasatch Mountains and elsewhere in Central Utah. These debris flows...
Morphologic and Hydraulic Adjustments of Red River from Shreveport, LA to Fulton, AK, between 1886 and 1980
Morphometric data (channel width and depth and slope) from 4 hydrographic surveys of Red River (1886, 1938, 1968, 1980) from Shreveport to Fulton and specific-gage analyses for the gages...
Channel Response to SCS Type-C Grade-Control Structures on Burney Branch, Mississippi
Five SCS Type-C grade-control structures were installed in Burney Branch in 1980 to remove 59.4 feet (18.1 m) of grade. The performance of the structures was evaluated in 1984 after they...
Ten Top Projects for 1988
