Emergency Regulations and the New Building Code
The 1942 Federal District Building Code was crude and overoptimistic. The 1957 earthquake prompted the drafting of emergency regulations, modern and more realistic. They evolved into the...

Thoughts on a Different Approach to Seismic Design Codes
The aim of this paper is to show that some of the principles on which conventional structural design is based are not directly applicable to seismic design. Seismic design, and the corresponding...

Probabilistic Site Strategy for Transmission Lines
A probability-based geotechnical site characterization strategy is presented for transmission line structures. Because site-specific data are sparse for these structures, a Bayesian model...

Transmission Structure Foundation Loads and Performance
Transmission line structures are subjected to unique loading conditions which for the majority of structures results in maximum loads which occur infrequently and act for only short periods...

Uplift Capacity of Model Group Anchors in Sand
Small-scale laboratory experimental results for the ultimate uplift capacity of shallow horizontal circular single and group anchors embedded in sand have been presented. The experimental...

Investigation of Excavatability in the Piedmont
The lateral and vertical variability of rock weathering in the Piedmont presents significant problems in evaluating the probable cost of excavation for deep basements, pipeline, road cuts,...

Technical Issues of Ground Water Data
Three fundamental issues to be considered in the design of ground water monitoring programs are 1) choice of parameters for characterizing contaminant sources, 2) determining the areal...

Managing Ground Water Data
Decisions concerning ground water protection and public health should be based on all relevant data, measured and analyzed with technically valid techniques. In areas where ground water...

Maritime Planning in New Zealand
This paper discusses maritime planning in New Zealand. After giving some background information, it deals with the statutory basis of such planning. It then looks at the Auckland experience,...

The Regulation of Private Waterside Development
To implement their Coastal Zone Management and Local Waterfront Revitalization Plans, towns and villages in the State of New York have been encouraged by the State to develop Harbor Management...

Maintaining the Gateway to the Columbia Basin?A Plan for Improvement
Portland District has begun a Maintenance Improvement Program to recommend procedures to reduce annual operations and maintenance costs while providing safe and efficient ship passage...

NOAA Weather Radio: The Source of Weather Information 24 Hours a Day
Weather plays an important role in the day to day affairs of coastal communities. The timely and accurate receipt of weather information is critical, especially during inclement conditions....

Coastal Structures and Long Term Shore Migration
Marco Island is a barrier island located on Florida's Gulf coast. Using an aerial photo time series from 1926 to 1981, shoreline migration is examined. Since shore development...

The Importance of Large Landsat Data Sets for Isolating Sediment Resuspension Processes
An optical density analysis of Landsat film transparencies would show spatial variations of suspended sediment concentrations. The residual optical density profile inversely shows above...

Wetlands Mapping in the Coastal Zone: Progress Towards a National Digital Data Base
To date approximately 90 percent of the coastal zone of the lower 48 states has been mapped by the National Wetlands Inventory (NWI). A number of Federal and State agencies have expressed...

Design of Breakwaters for Hurricane Wave Attack
The breakwaters protecting Port of Haina in the Dominican Republic have been repeatedly damaged by hurricane storm waves. Attempt to repair the destroyed portions have been largely unsuccessful....

St. George Harbor?A Berm Breakwater Solution in Alaska's Bering Sea
The berm breakwater concept is based on the premise that locally available materials should be used in breakwater construction to the largest degree possible. By looking at failure dynamics...

Design Features of the Elliott Bay Marina
The paper presents a summary of the major coastal engineering design features of a new Puget Sound small craft harbor proposed for construction within the City of Seattle. The 1,200 berth...

Construction of Fisherman's Wharf Breakwater
The San Francisco District of the United States Army Corps of Engineers recently completed construction of a breakwater at Fisherman's Wharf. The construction, completed ahead...

Institutional Constraints to Coastal Zone Management: A Case Study of Hawaii (abstract)
The problems that plague Hawaii's coastal zone management are primarily the result of 'institutional' factors, some of them rather unique. These...
