Monitoring Saves a Site
A comparison is made of two supported excavations that were similarly designed and constructed. Both excavation support systems consisted of a soldier pile and lagging sheeting wall supported...
Critical Load Program
The elastic critical load of a structural frame is a fundamental parameter in assessing its stability. It is an upper bound to the failure load of the frame, in the same way that the Euler...
A Road to Recovery
Inspections of the Golden Gate Bridge revealed that the bridge had localized corrosion near its expansion joints, corrosion of its reinforcing steel, and was severely contaminated with...
Civil Engineering in the Arctic Offshore
The 123 papers included in this publication describe the present state of practice, consider emerging concepts and requirements, define research and development needs and critique present...
An Economic and Financial Planning Model
A comprehensive computer model for generation planning has been developed and applied to several large-scale power sector master plans. A unique feature of this model is the concurrent...
Diagnosis of Wastewater Treatment Processes
This paper presents an approach to the development of an expert system for aiding the operation of an activated sludge wastewater treatment facility. The expert system incorporates a diagnostic...
Modular Plastic Media for Shallow Bed Trickling Filter Applications
Little specific data is available for less sophisticated trickling filter systems which employ recent plastic media designs for shallow bed filters without the added cost of subsequent...
Optimization of Variable Volume Diaphragm Filter Presses
The St. Paul, MN, Metropolitan Waste Control Commission Wastewater Treatment Plant has installed and operated eight variable volume diaphragm filter presses for four years. During this...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
The Engineering Aesthetics of Tall Buildings
The Proceedings of a session on the Aesthetics and Design of High-Rise Buildings at the ASCE Convention in Denver is included in its entirety. The session was chaired by Lynn Beedle and...
Optimization Issues in the Design and Control of Large Space Structures
The optimization and identification issues which arise in the design and control of large flexible space structures are reviewed. The first paper examines the use of several different...
After Action Report 1983 California Coastal Storms
The winter of 1982-1983 saw some dramatic changes in the worldwide weather patterns that have been attributed to the anomaly known as El Nino. During that winter California was attacked...
Coastal Erosion Management in Australia and the U.S.
Current knowledge and management policies in both Australia and the U. S. favor non-structural over structural responses to coastal erosion problems wherever possible. The trend towards...
Regional Waterfront Planning Without a Superagency: Can Existing Agencies Fill the Gap?
As far back as 1966, the Regional Plan Association saw the potential for mixed use development of underutilized and vacant land along New Jersey's Hudson River Waterfront....
Who's Minding the Beach?...The Virginia Experience
Virginia entered the realm of statewide funding for the enhancement of public beaches on July 1, 1980 with the creation of the Commission on the Conservation and Development of Public...
Constraints on the Use of Development Management to Reduce Coastal Storm Hazards
This paper has presented some important information about perceived constraints to the enactment and effective implementation of development management measures to reduce coastal storm...
Guidelines for the Mitigation of Salt Marshes in New Jersey
Mitigation is the environmental compensation for human impacts and disturbances on sensitive and legally protected ecological systems. The primary goal of mitigating human developments...
Stabilization of Dunes with Flexible Mattresses
Dunes, constantly moving due to influences of sea and wind, are inherently unstable and in many, if not most situations, are best left in their natural state of change. Where there is...
Foreshore Treatment as a Method of Coastal Protection
This paper describes the damages sustained by a small section of the Vancouver, British Columbia coastline during the passage of a storm in December, 1982. This stretch of protected coastline...
Man-Made Offshore Islands: An Innovative Solution to Coastal Erosion
Existing shore-parallel detached breakwaters have resulted in the accretion of sand along the shoreline in the wave shadow of the structure. Significant prograding of the beach has replaced...
