South Jetty Scour Hole Stabilization, Ocean City, Maryland
Formation of a scour hole along the inlet side of the South Jetty at Ocean City occurred after jetty construction as a result of ebb tidal flow in the inlet. Analysis of historical bathymetry...
Use of Portable Simulator in Designing Channel Improvements for Port of Brownsville, Texas
The Port of Brownsville, located at the southernmost tip of Texas, serves as an import/export port for both southern Texas and northern Mexico. The proposed channel improvement project...
Design of a Mechanical Refuse Barrier
In the summer of 1988, beachgoers flocking to the New Jersey shore for relief from unusually hot, hurried weather were stunned by the grisly spectacle of hospital debris, industrial and...
The Talbert Channel Ocean Outlet Project
The Talbert Channel Ocean Outlet Project consisted of relocating and enlarging the outlet of a relatively narrow, shallow flood control channel in Southern California. Noteworthy aspects...
Role of the Coastal Engineer in Civil Engineering Practice
Coastal engineering is a specialized discipline of civil engineering that encompasses a wide variety of activities related to harbors, navigation, shore erosion and storm protection. Because...
Should the U.S. Accept the Concept of Navigable Depth?
Navigable depth is defined as the maximum depth of water from the chart datum that is safe to accept as the bed of the channel, such that damage does not occur to a ship's hull and maneuverability...
Computation of Flow in Ice-Covered Dune-Bed Channels
A numerical method for solution of the Reynolds-averaged Navier-Stokes equations is developed to study the flow over sand dunes in two-dimensional channels. The method is applied to calculate...
Erosion of Steep River Banks and Time Evolution Towards Equilibrium Channel Shape
A numerical analysis of the time evolution of straight river channels is presented. The bed and bank, material is taken to be coarse, non-cohesive and uniform in size. As a result of the...
A Multiple Disk Centrifugal Pump as an Artifical Ventricle
A pulsatile, multiple disk, centrifugal pump has been analysed and tested for potential use as an artificial ventricle. The pump is similar to a Tesla Turbine design which consists of...
Structural Design of the GN&C Navigation Base for the Space Station Freedom
The Space Station Freedom (SSF) pointing accuracy budget requires that the Guidance, Navigation and Control hardware maintain alignment within ? 0.1 degrees of arc. The ring laser gyros...
Tide- and Wind-Driven Flushing of Boston Harbor, Massachusetts
The flushing of Boston Harbor, a shallow, tidally dominated embayment with little fresh water input, is investigated using a depth-averaged model. The modeled tidal currents exhibit strong...
DYNLET1: Network Model for Tidal Inlet Dynamics
This paper introduces DYNLET1, an efficient, versatile, and accurate one- dimensional numerical model for computing tidal flow in a system of interconnecting channels and bays. Drawing...
Coastal Engineering Practice
This proceedings contains 70 papers presented at the American Society of Civil Engineers Specialty Conference Coastal Engineering Practice '92 held at Long Beach, California,...
Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...
Beyond Push-Button GPS
In 1993, the U.S. Air Force Space Command will complete its deployment of 24 satellites for the Global Positioning System, affording 3-dimensional positions and velocities 24 hours a day...
Summary Conclusions & Recommendations of the 1991 Washington State Ports and Transportation Systems
Since 1975, the Washington Public Ports Association and Washington State Department of Transportation (WSDOT) have conducted periodic performance assessments of the state's ports, waterways,...
Modifications to Coal Pier 6 Made Necessary by a Deeper Channel
In 1987 it became apparent to the Norfolk Southern Corporation that the U.S. Army Corps of Engineers proposed dredging of the Norfolk, Virginia Harbor would become a reality. Coal Pier...
Riprap Design in Marine Terminals
Navigation vessels in otherwise quiescent waterways sometimes generate forces that require stabilization of the bed or banks. Since riprap is an accepted and dependable means to armor...
Environmental Monitoring and Operator Guidance System (EMOGS) for Shallow Water Ports
Port facilities have increasingly been required to accommodate longer and deeper draft ships. Existing approaches to many ports consist of long shallow channels which can make transits...
Risky Business: Can We Believe Port Risk Assessments?
What is the risk that a maritime incident resulting in catastrophic consequences (environmental damage or loss of life) could occur in a U.S. port or waterway? How does one calculate the...
