Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...

Interaction of Geology, Construction Practice and Foundation Design
The influence of geologic knowledge and construction practices on the geotechnical foundation design process has been assessed and summarized. Particular emphasis has been given to the...

Building on the Coastal Barriers Resource Act
In 1982, the Coastal Barrier Resources Act (CBRA) was enacted to minimize the loss of human life, wasteful expenditure of Federal revenues, and damage to fish and wildlife and other natural...

Erosion and Washover in Coastal Louisiana
In 1985 three hurricanes affected the barrier coastline (Caminada-Moreau Headland) of Louisiana. These produced severe coastal erosion and rapid washover extension. Using the 1979 U.S.G.S....

Environment Exploitation by Prehistorical Population of Rio De Janeiro
The specific purpose of this project was to establish the cultural contexts in the area being studied as well as to define the mechanisms of environmental manipulation that were employed...

Perceptions of Architects Regarding Use of Computers and Educational Requirements for Architectural Technicians
This paper identifies those cognitive competencies common to all CAD programs to determine which will best prepare the students for entry-level CAD proficiency and flexibility within the...

Perspectives on Irrigation/Drainage Education and Training
The Task Committee on Water Resources Education and Training (TCWRE) was organized in 1985 for the purpose of conducting an opinion survey to assess the adequacy of current education and...

100 Years of Sedimentation Study by the USGS
On January 15, 1889, the U.S. Geological Survey began collecting sediment data on the Rio Grande at Embudo, New Mexico. During the past 100 years the U.S. Geological Survey's...

An Overview of Computer Stream Sedimentation Models
This paper discuss some of the author's experience in computer modeling of stream sedimentation problems. Comparisons of twelve selected models developed and implemented in...

Areal Sampling Techniques
Three areal methods, commonly used for sampling the coarser surface layer of gravel-bed streams, are examined. An idealized sediment deposit, that consists of cubic particles and accounts...

Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability
One of the main purposes of the ASCE Task Committee on Analysis of Laboratory and Field Sediment Data Accuracy and Availability is to assemble worldwide sedimentation data from field and...

Statistical Frequency Analysis of Flood Records
The U.S. Geological Survey, like other Federal agencies, uses Hydrology Subcommittee Bulletin 17 for guidance in statistical frequency analysis of flood records. This paper describes the...

Regionalization of Flood Characteristics
Regionalization procedures are used to transfer flood characteristics from gaged to ungaged locations. These procedures are an extension of the gaging network that allows planners and...

Urban Watershed Data for the United States
The contents of an urban watershed data base compiled for a national urban flood-frequency study by the U.S. Geological Survey are described. The data base includes information for 269...

Underwater Tunnel Inspection by Virginia Power Using a Submersible Robot
The Bath County Pumped Storage Station, jointly owned by Virginia Power and Allegheny Power systems and operated by Virginia Power, has three large tunnels linking the upper and lower...

Preventive Maintenance: Fixing What Ain't Broke
Municipalities are often caught in the cycle of built-neglect-rebuild. For bridges, the solution is preventive maintenance: keep the bridges clean and painted, and they'll...

The Potential Realtime Application of GPS Phase Tracking in Construction Surveying
The potential use of precise Global Positioning System (GPS) phase tracking receivers in a realtime application is discussed in relation to the advancements to date in precise kinematic...

Adapting Tunneling to Rocks of the Sierra Nevada
Exploration programs were completed to select the most economical tunnel routes which are not only the shortest but are those which can be excavated by tunnel boring machines with the...

Optimisation of Bulb and Kaplan Turbine Runners
The paper presents a brief survey of the theoretical method used so far at Turboinstitut Ljubljana for axial runner design and analysis. Theoretically optimised runner is later experimentally...

Field Testing: Producing Complete Test Results on Site, A Realistic Objective
Modern technologies and instruments have had an influence in nearly every field imaginable. At Hydro-Quebec, the last ten years have brought about a complete transformation in the way...
