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...

Plunge-Pool Scour by Inclined Jets
A series of experiments were performed in a sand-bed plunge pool with circular jets produced by nozzles at different angles and elevations and conveying different flow discharges. The...

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...

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...

Adaptive Instructor Model for an Engineering ITS
To develop intelligent tutoring systems (ITS) for engineering via computer technology, a model of how engineers learn as well as methods in which instruction should occur must be captured...

Computer Fluent Civil Engineer: What Does it Mean?
The rapidly changing arena of computer and information technology has an impact on civil engineering education, what is taught, how it is presented, type of homework, maintaining computer...

Exchanging Layout and Schedule Data in a Real-Time Distributed Environment
Unpredictable site conditions and unforeseen changes in construction work may result in inefficiencies due to a shortage of work space and difficult access to critical areas on site. This...

Total Quality Management for Information Technology
Recently, there has been an increased awareness in the AEC firms toward Total Quality Management (TQM). Many AEC firms and the public sector started to look seriously at TQM. The reason...

Information Technology: Panacea or Poison?
Consulting engineering is entering a period of dramatic change which will provide opportunities and threats. Pressure on fee levels and changing markets are necessitating a greater emphasis...
