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...
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...
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...
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...
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...
Computer Modeling of Collection Systems for Sulfide Evaluation (
An overview of two computer models and a nomograph model for sulfide prediction is presented. The first program, 'SULF. BAS', is a Basic Language computer model...
Risk-Based Design of Inspection Programs for Detecting Leaky Underground Storage Tanks
A mathematical framework is developed for estimating the effectiveness of large-scale inspection programs for leaky underground storage tanks. The framework incorporates the leak likelihood...
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...
Models of Organics Transport Through Soil Columns
A mathematical model is proposed for the transfer of organic solutes in soil. Two cases are considered namely transport of non-adsorptive solutes and transport of adsorptive solutes. Comparative-study...
Modeling the Movement of Volatile Organic Chemicals with Unsaturated Flow
Over the past decade, the rate of groundwater contamination by volatile organic chemicals (VOCs) has increased. Therefore, for both groundwater protection and cleanup, it is necessary...
Modeling Dispersion in Non-Homogenous Formations
A stochastic model of contaminant mixing in non-homogeneous porous media has been developed. The model is three dimensional and relates the contaminant distribution to the probability...
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...
