Pipe Spillway Plunge Pool Design Equations
An equation is given to determine if scour holes will beach and widen excessively. For nonbeaching scour holes, dimensionless equations are given for the progression of scour with time...
Avoiding Cavitation Damage to Hydraulic Structures
Cavitation damage often may be avoided by not allowing cavities to form. Where boundaries are not deeply submerged, their shape must be exactly correct, irregularities must be very small,...
Leaching Analysis of Coal Mine Spoil Material
Arch Mineral Corporation has conducted a column leaching study to analyze the leaching characteristics of surface coal mine spoil material in order to predict post-mining groundwater quality....
Plastic and Other Limit State Methods for Design Evaluation
These proceedings consist of seven papers dealing with the topic of the design of complex structures using limit state methods. The emphasis is on the role of plastic or limit load techniques....
Structural Plastics Design Manual
The structural behavior of plastics reflects a number of characteristics different from those of the metal, lumber, and concrete materials familiar to most design engineers. This manual...
Jordans Precast Airport
The design and construction of the New Queen Alia International Airport in Amman, Jordan required extensive innovation and site adaptation to integrate international standards with the...
Alluvial Fans: Novel Flood Challenge
After disastrous floods hit Cabazon, Calif., engineers faced the challenge of balancing concerns about protecting property and life (by limiting or prohibiting construction) against the...
Asphalt: Great Expectations
A $50 million, five year research program has been proposed for research into asphalt as part of the larger ($150 million) Strategic Transportation Research Study (STRS). The research...
Dredging and Dredged Material Disposal
Waterborne commerce is a major factor in the economy of many countries. Because waterborne commerce depends on the ability of nations to provide adequate navigation channels to transport...
Measurement of Hydrographic Parameters in Large Sand-Bed Streams from Boats
This report concentrates on the state-of-the-art in the field documentation of the existing channel geometry, plus the concurrent stream flow and sediment transport characteristics, prevailing...
Recent Developments in Pavement Skid Resistance
As pavements wear, they lose some of their skid resistance. This article discusses some of the leading options for restoring a pavement's skid resistance. The possibilities...
Superplasticized Concrete Takes Off in Dallas
Some engineers are calling superplasticized concrete the most important advance in concrete technology in over three decades. Over the past four years superplasticized concrete has begun...
Pre-Engineered Metal Buildings: The Story Behind Their Rapid Growth
In 1964, pre-engineered metal buildings accounted for 24% of new non-residential, low-rise construction. By 1981, that figure had jumped to 56%. Behind that rapid growth are some very...
Recent Advances in Engineering Mechanics and Their Impact on Civil Engineering Practice
The emphasis of these proceedings is on contributions and advances in the areas of solid and fluid mechanics that advance civil engineering practice. The main topic considered are, computers...
Ice and Snow Utilization in Cold Regions Construction
An overview of requirements is presented for the planning, design, and construction of roads, pads, and airfields using water, ice and snow as construction materials. Practical guidelines...
Cold Regions Earthwork
The purpose of this paper is to outline the state-of-the-practice in cold regions earthwork based on experience gained in the Prudhoe Bay area of Alaska. Material properties of fill used...
Existing Sewer Evaluation and Rehabilitation
Guidlines for the evaluation and rehabilitation of sanitary sewers are presented. The purpose and scope of sanitary sewer rehabilitation is described. The major emphasis is on filtration...
Structural Lumber: An Overview of Research Needs
Structural performance of lumber is influenced by the processing steps from forest to final end-use and by the end-use environment. Research needs in processing include: 1) selection of...
