Sediment Transport in Sewers and Design Implications
Extended studies on sediment transport in sewers were conducted at the University of Newcastle upon Tyne and using this new as well as previously available data an attempt has been made...
Theoretically-Derived Regime River Width
The governing equations describing the motion of fluid and non-cohesive sediment particles in alluvial channels are combined to analytically determine the equilibrium surface width of...
Equilibrium Geometry of Channels with Cohesive Banks
An optimization model is used to assess the stability of gravel-bed rivers with cohesive channel banks and to determine the effect of the bank stability on the equilibrium hydraulic geometry....
Width Adjustment: Relative Dominance in Unstable Alluvial Streams
The mechanisms that control the relative dominance of width adjustment in unstable streams are described. Specifically, the role of the following factors affecting the fluvial environment...
Field Evaluation of the Sediment Transport Model Stream with a Bank Erosion Component
The graded sediment routing and stream bed evolution model STREAM of Borah, Alonso and Prasad was expanded earlier by incorporating a riverbank erosion component of Osman and Thorne. In...
Relation of Unit Gravel Discharge to Mean Velocity
In sand-bed streams, the unit discharge of sand varies approximately with the fifth power of the mean velocity and inversely with the median diameter of the bed sediment. Similar relations...
Bed Material and Numerical Modeling in a Gravel/Cobble Bed Stream
The characteristics of bed material in a cobble or gravel river and their use for numerical simulation of flushing flow needs are discussed. There are three types of bed material: 1) material...
Sediment Transport Analysis Rio Grande Floodway at San Marcial Gauge
A detailed analysis of sediment transport data collected on Rio Grande Floodway at San Marcial gauge shows that the all-year total load rating curve and the seasonal rating curves yield...
Local Scour Potential for Large Bed Material with Shallow Tailwater Depth
Jet momentum acting on a bed particle and submerged jet diffusion theory were employed to derive scour prediction formulas in a plunge pool. Semi-theoretical formulas were suggested for...
Performance of Submerged Vanes for Control of Sediment in an Irrigation Canal
Removal of accumulated sediments from irrigation canals is necessary in order to maintain canal capacity. Removal of these sediments may be enhanced by directing and concentrating sediments...
Non-Point Pollution Loadings and their Impacts on Tennessee Valley Reservoirs
This is a three-year study which began in March 1992. The project has focused on inflow streams entering storage projects including Douglas, Cherokee, South Holston, Watauga, Norris, Chatuge,...
Fortification of MMOC Models for Steep-Channel Flows
The Multimode Method of Characteristics(MMOC), designed to solve unsteady flows, is a new comprehensive scheme formulated by merging several individual characteristic schemes of the specified-time-interval...
Bearing Capacity of Soils
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 7 This U.S. Army Corps of Engineers engineering manual...
A Thousand Points of Data
Significant cracking was discovered in a multistory parking garage shortly after construction. Was it safe to open? Based on visual inspection, a bridge was down-rated, with potential...
Computer Calculations Speed Tunnel-Lining Design
A computer program handles the computations and simplifies a method that sets forth the vast amounts of tunnel concrete lining design information in a single diagram. Using the principle...
Let's Go to the Videotape
Illustrating a design concept to educate and soften the resistance of community groups, environmentalists, government regulators and funding agencies is not a new idea. But the state of...
Predicted and Measured Behavior of Five Spread Footings on Sand
This publication contains the results of a full scale load testing program used to predict and measure the bahavior of five spread footings on sand. These results were presented at the...

Hurricanes of 1992
Lessons Learned and Implications for the Future
In 1992, Hurricanes Andrew and Iniki devastated portions of Florida, Louisiana, and Hawaii causing over $35 billion in damages and the loss of 38 lives. Hurricane Andrew, which accounted...
Columnless in Chicago
The United Center in Chicago is now home to the Bulls basketball team and the Blackhawks hockey team. The arena features luxury suites, a column-free interior and unobstructed views. An...
