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...
The Application of Computer Simulation in the Design of Marine Terminals and the Scheduling of Ship Traffic
This paper describes a software package which simulates the operations of marine terminals. The computer programs were designed to assess the effectiveness of the available design alternatives...
Marina Design and Environmental Concern
Research initiated by a Florida Cabinet Resolution of August 6, 1974, has generated two models for the evaluation of the impact of marina development on coastal waters. One, a complex...
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...
Marina Flushing and Sedimentation
The paper discusses a one-dimensional circulation model for the marina. Tides are modeled as long waves and are assumed to be much longer than the marina. This circulation model is coupled...
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...
Berthing Impact Force Distribution on Pile Supported Pier Structures
This paper investigates the degree to which a berthing impact force is distributed to the pile bents of batter pile supported pier structures. A procedure is developed to estimate the...
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,...
Berthing Simulation Method for Fender System
For the design of marine fender systems, berthing and mooring forces should be taken into account. Berthing forces are considered in this paper. A unique berthing simulation method has...
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...
Los Angeles and Long Beach Harbors Tidal Circulation Study
Expansion of harbor facilities frequently involves placement of additional landfill and the deepening of channels and mooring areas. A numerical tidal circulation model was used in the...
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,...
Analytical and Empirical Methods for Predicting Channel Shoaling
Many techniques have been used in the past to predict the effects of channel enlargement on channel shoaling. These range from rule-of-thumb predictions to elaborate physical model investigations....
Plugging into a Dam
Instruments are embedded into hundreds to dams around the world. But for instrumentation to be effective, the instruments must be read, and the data must be plotted and compared to predicted...
Physics-Based Modeling of Lakes, Reservoirs, and Impoundments
This book provides an overview of considerations that apply to modeling flow and transport in lakes, reservoirs, and impoundments using equations based on conservation principles. Specific...
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...
Electrical In Situ Measurements for Predicting Behavior of Soils
A new method is presented for predicting the in situ stress-strain behavior of fine grained soils based upon in situ measurements of its electrical properties. The method involves the...
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...
A Field Study of Water Movement Through Clay Liners
A monitoring system has been designed for the field verification of a numerical model of water movement through the cover clay liner of hazardous waste landfills. The most unique aspect...
