Group Effect in the Case of Downdrag
A summary of the various techniques available to calculate downdrag forces on pile groups is presented. In light of all these existing techniques, a simplified method is recommended. An...

Analysis of Geometric Mispositioning in a Vertical Pile Group
A straightforward procedure is described whereby an approximate, three-dimensional, nonlinear model for the analysis of pile groups is used to simulate errors in major group parameters...

Use of Bar Code Technology to Simplify Sieve Analysis Data Acquisition
A system has been developed at the U.S. Army Corps of Engineers Ohio River Division Geotechnical Engineering Laboratory using bar codes and a computer coupled balance to aid in data collection...

Methodology for Optimizing Rock Slope Preventative Maintenance Programs
Rock slopes along transportation routes can fail in several different modes, with various types and magnitudes of consequences. The 'risks' associated with such...

Foundation Evaluation of Barkley Dam for Seismic Analysis
An in-situ site investigation was performed at Barkley Dam, KY to gather essential information on the stratigraphy and nature of the foundation soils. From this information the site was...

Finite Element Analysis and Field Instrumentation of a Soil/Cement Arch
A two dimensional plane strain finite element analysis is used to predict the increase in stress on an existing tunnel caused by the addition of twelve feet of fill. The fill, soil/cement,...

Hugo 1989 - The Performance of Structures in the Wind
The performance of buildings in the Carolinas during Hurricane Hugo, 21-22 September 1989, is reviewed. Wind speeds in most locations were below the design levels specified in the local...

Lessons Learned by a Roof Consultant
Hurricane Hugo left in its wake, extensive damage, an estimated $6 Billion loss. It is estimated that over 80% of the losses were related to roof failures, and the associated water damages....

A Post Hurricane Hugo Transportation Study
Hurricane Hugo will remain in the minds of South Carolinians for many years to come. This hurricane attracted most of the world's attention in 1989 as it devastated every...

Classification System of Environmental Units for Land Use and Coastal Planning in Baja California, Mexico
The incidence of development on Baja California's coastal zone has produced an excessive demand on coastal resources with degradation of the environment and conflicts in land...

Effect of Shell on Beach Performance: Examples from the West-Central Coast of Florida
Time-series analysis of beach profiles and sediment analysis along the Pinellas County coast of Florida over a 2-yr. period shows that shell abundance has an influence on beach performance....

The Impact of the October 17, 1989 Loma Prieta Earthquake on Coastal Bluffs and Implications for Land Use Planning
The October 17, 1989, Loma Prieta earthquake caused bluff failure along 100 miles of coastline between San Francisco and central Monterey Bay in a variety of rock types and slope conditions....

Earthquake Measures for California OCS Platforms
The ability of a platform to withstand earthquakes is one of the primary design factors for platforms on the California outer continental shelf (OCS). This paper discusses (1) the special...

The Width of the New Artificial Channel of the Port of Lisbon?An Application of the SIMNAV Simulation Model
The study of the width of the new artificial channel for the entrance of the port of Lisbon (in the Tagus estuary), which will allow the passage of fourth generation container ships, is...

Sponge Distribution at Arraial do Cabo, SE Brazil
Spatial and temporal distribution of shallow water sponges were studied on southeastern Brazilian rocky coasts by means of qualitative and quantitative samples made by SCUBA diving. Cluster...

Foundations and Breakaway Walls of Small Coastal Buildings in Hurricane Hugo
After Hurricane Hugo a survey of damage to small, coastal buildings was conducted in North and South Carolina. The performance of elevated foundations, breakaway walls and foundation cross...

Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...

Headland Breakwaters in the Chesapeake Bay
The purpose of this paper is to document and evaluate the use of headland breakwaters in the Chesapeake Bay. Headland breakwater systems have been installed in the Chesapeake Bay since...

Field and Numerical Investigations on Siltation Mechanism in Kumamoto Port
Synthetic investigations on siltation mechanism in Kumamoto Port were carried out by field observations, laboratory tests, and numerical simulations. Natural conditions such as tides,...

Design and Implementation of a Coastal Resource Geographic Information System: Administrative Considerations
A Geographic Information System (GIS) is a data management and information analysis system that allows the capture, synthesis, generation, retrieval, analysis and output of spatial data....
