Getting Along: The Geotech and the CM
The opinions of geotechnical engineers are usually respected within a consulting firm, but when such a specialist gets out in the field, he or she is seen as merely part of the backup...

Computer Scheduling and Construction Specs
As recently as the early 1980s, employing computers in critical path method (CPM) scheduling was a formidable decision demanding considerable commitment of time and resources by management....

A Solid Waste Solution
Burgeoning growth and diminishing landfill capacity have been propelling Broward County, Fla. toward a solid-waste crisis. The county, located along Florida's southeastern...

Research Needs in Hydraulic Engineering
The information presented herein has barely dented the surface of the needs for hydraulic research, and of the methods required to obtain funding for that research. The responses and reports...

Current Legal Issues in Sedimentation
This paper represents the updating of Chapter 7 for Manual 54. There has been considerable change in legal rulings and precedent law since the first edition of Manual 54. Many of these...

Updating Chapter II?Sediment Transportation Mechanics
Chapter II, the most comprehensive chapter of the Sedimentation Engineering Manual, has aged. The manual prepared by the Task Committee for the Manual on Sedimentation was published by...

Engineering Geomorphology
Engineering geomorphology is the application of geologic and geomorphic principles to the solution of river engineering problems. Development of a process-based understanding of a problem...

Wetland Management in Britain: A Comparative Approach

Protecting the Boca Raton Outfall Before and After Hurricane Andrew
A critical factor for the success of an ocean outfall is its ability to remain intact and functional for many decades of service, despite extreme episodes of wave attack and beach erosion....

Scour Analysis for Bridges over Missouri and Mississippi Rivers
Engineering services are being provided for three bridge crossings, two over the Missouri River and the other over the Mississippi River. Scour consideration for the bridged waterways...

Pier Scour Equations Used in China
This report describes the equations used in the People's Republic of China for estimating scour depth at bridge structures. The equations were worked out from model and field data at the...

Calibration of Manning's Roughness for a River Reach
The Albuquerque Projects Office of the U.S. Bureau of Reclamation collected water surface elevations for measured discharges for the Rio Grande and many of its tributaries to try to obtain...

Fluid Mechanics Aspects of Ocean Outfalls
Prediction of the environmental effects of ocean outfalls requires understanding of some complex fluid mechanical phenomena. These include the dynamics of merging plumes in flowing, density-stratified...

Sediment Disposal and Transport in Central SF Bay
