Risk Management of Oceanfront Resort Operations
The perception of high incidences of accidents related to open ocean recreational activities in Hawaii and the need for developing educational programs on water safety for resident and...
Restoring of Butcher's Slough Estuary?A Case History
A 30-acre parcel of former lumber and plywood mills occupying original estuary and salt marsh wetlands on the northern edge of Humboldt Bay, Humboldt County, north coastal California,...
Emergency Shore Protection
Emergency shore protection usually requires design and construction to be completed in a 2 to 3 week period. Emergency shore protection measures at Surfside and Ventura, California required...
Innovations in Dredged Material Disposal in Puget Sound
This study, known as the Puget Sound Dredged Disposal Analysis (PSDDA), is building on a strong history of federal/state cooperation within Washington which is unique in the United States....
Aquatic Dredged Material Disposal in New England
The Disposal Area Monitoring System (DAMOS) is a large multi-disciplinary environmental monitoring program instituted by the New England Division (NED) of the U. S. Army Corps of Engineers...
Methods for Developong a Management Plan for a Small Tidal Inlet: Mecox Inlet, Long Island, New York
Few management studies have examined small ephemeral tidal inlets. The magnitude of short-term shoreline changes associated with some ephemeral inlets makes desirable the development of...
Managing the Coastal Heritage of Australia
The concept of heritage spaces as a part of open-space systems has been evolving in Australia over the last 15 years. This paper overviews the main approaches that have been developed...
Timber Bulkheads
Timber bulkhead design and construction methods are presented in this publication for consideration by the engineering profession. Included are papers on an analytical method for the design...
Optimization: An Emerging Technology
The technology of formal, numerical structural optimization is neither mysterious nor complex. Software programs are now available for use by engineers who do not have detailed knowledge...
Worth a Thousand Words
In recent years, microcomputers have grown powerful enough to take over many of the functions that once, only a mainframe could understand. In addition, they have added a few tricks of...
Building Frame Analysis in Basic
Moment distribution has, for the past 30 years, been the most popular method of analysis for statically indeterminate structures. Programmed in Basic for the microcomputer with relative...
Philosophy and Implementation of Gate Stroking
The purpose of this paper is to examine one control method - gate stroking - the philosophy which would lead to its selection and an example of its implementation. Gate stroking provides...
An Uncertainty Analysis Methodology Applied to Sheetpile Cofferdam Design
The input data to numerical simulation models is often uncertain, and, consequently, model predictions may be uncertain. Such uncertainties are often treated by Monte Carlo techniques....
Stepped Spillway Design with a RCC Dam
The hydraulic model study results for the Upper Stillwater stepped spillway design are presented. The studies encompassed several spillway geometries and design unit discharges ranging...
Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...
Mathematical Simulation of Halocarbon Distributions in Boston Harbor
In an effort to better understand the sources and transport of effluents, a combined modeling and field measurement program has been initiated. The modeling uses a pair of 2-D (depth-averaged)...
Spline Interpolations for Water Hammer Analysis
The method of characteristics (MOC) with spline polynomials for interpolations was investigated for numerical water hammer analysis. The overall accuracy is significantly improved compared...
Computation of Supercritical Flow in Open Channels
The use of two explicit, shock-capturing, finite-difference schemes, Lax and MacCormack, for the solution of two-dimensional shallow-water equations in steady, supercritical flow is investigated....
Analysis of Scour Problems at Louisiana Bridges
An ongoing project to automate the monitoring of scour measurements at Louisiana bridge sites is discussed. The data at selected bridges is digitized and put into computer files for analysis....
A Semianalytical Method for Solving Unsteady Flow Equations
This paper proposes a method that uses conjunctively the Laplace transform for continuous time and finite element for spatial discretization to solve unsteady flow equations. Laplace transforms...
