TLMRF Research Initiatives
The research initiatives of the EPRI (Electric Power Research Institute) structural development project RP2016-03 are described. The interrelationship of these initiatives with cosponsored...
Upper Delaware River Ice Control?A Case Study
During February 1981 a castastrophic breakup ice jam occurred along a reach of the Delaware River near Port Jervis, NY, causing 14. 5 million in damages. In February 1982 another breakup...
The Electric Power Research Institute's TLWorkstation?
The initial version of the Electric Power Research Institute's TLworkstation software system is described. The factors influencing the software design and the programming...
Systems Model for Water Supply Following Earthquakes
The water supply for San Francisco is described with emphasis on the city's auxiliary water distribution network, which provides fire protection for the most heavily built-up...
Design and Construction of the Spirit Lake Outlet Tunnel, Mount St. Helens, Washington
In 1982, a governmental task force was formed to evaluate the hazard posed by the blockage of Spirit Lake that resulted from the eruption of Mount St. Helens in May 1980. An analysis was...
An Expert System for Construction Schedule Analysis
This paper describes a prototypical expert system for the analysis and evaluation of construction scheduling networks from an owners' perspective. The knowledge base, which...
An Expert System for Flood Estimation
This study was made to investigate the feasibility of expert systems for solving certain engineering problems. A prototype system was developed to demonstrate the applicability of these...
Active Control of Distributed Parameters Structures by Pointwise Control Actions
Several methods have been offered to control a structure. These methods are the optimal control, the pole assignment, the independent modal space control, and the direct velocity feedback....
Blasting Densifies Sand
Constructing the Jebba Dam on Nigeria's Niger River required in-place densification of large volumes of loose sand to record depths of up to 131 ft. Vibrocompaction was used...
Siltation of the Port of Astoria
Sedimentation rates suddenly increased in the Port of Astoria, Oregon, immediately following the May 18, 1980 ash eruption of Mt. St. Helens. This ash was transported down the Columbia...
Design Concepts for Floating Breakwaters
This paper describes a fundamental approach to the design of a floating breakwater based on the concepts of dynamic analysis of floating bodies. The process results in a relatively simple...
Waterfront Parks in the Boston Area
Two recently completed waterfront parks in Cambridge and East Boston, Massachusetts are discussed. The Bird Island Flats 'Harbor Walk' project is a 15-foot wide,...
Navigation Channel Design for Safe and Efficient Ship Transit
The U. S. Army Engineer Waterways Experiment Station (WES) recently conducted a hydraulic model investigation of the western portion of Cleveland Harbor, Ohio. This study provided data...
Channel Design Criteria and the Houston Ship Channel
Channel design literature is reviewed and compared with operational limits currently on the Houston Ship Channel (HSC). It was found that in all aspects of channel design considered (depth,...
Field Permeability Test for Earthen Liners
A sealed double-ring infiltrometer (SDRI) was developed for in-situ measurements of the hydraulic conductivity of earthen liners and covers. The characteristic of the SDRI that distinguishes...
High Quality Sampling and In Situ Testing for Deep Water Geotechnical Site Investigation
This paper discusses methods that have been used to conduct geotechnical investigations in water depths up to 2500 feet. Investigations can be conducted from supply boats, geotechnical...
Ports '86
Ports '86 had the theme of Innovations in Port Engineering and Development with keynote speakers looking ahead to Port Development in the 1990's. The program...
Clay Liner Hydraulic Conductivity: Comparison of Field & Laboratory Tests
Clay liner hydraulic conductivities at three hazardous waste landfill cells in Oklahoma and Utah were measured in the laboratory and in the field during construction. Prior to construction...
Clay Liner/Leachate Compatibility Modeling
Over the past several years, the results of many laboratory studies assessing the effect of various combinations of organic and inorganic chemical mixtures on the hydraulic conductivity...
Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...
