Numerical Beach Profile Modelling for Beachfill Projects
The use of beachfill in addressing coastal erosion problems is becoming increasingly popular. It is often more attractive than the conventional structural approaches for economic, aesthetic...
Application of a Beach Plan Evolution Model in Sergipe, Brazil
An offshore breakwater 543 m long located at about 2.4 km from the shore at 10 m of water depth (above chart datums) provides protection to a liquid bulk terminal (Terminal Portuarlo de...
Reformulation Efforts for Panama City Harbor, Florida
Panama City Harbor is on St. Andrew Bay, an arm of the Gulf of Mexico, about 105 miles east of Pensacola and 230 miles northwest of Tampa. At the request of the non-Federal sponsor, the...
Comparison of Model and Field Results for Barbers Point Harbor
As waves travel into harbors from deep water, nonlinear processes lead to transfers of energy from the wind wave frequencies to long waves with periods of the order of several minutes....
A Dual Approach to Low Frequency Energy Definition in a Small Craft Harbor
Low frequency wave energy in a small craft harbor is examined through comparison between a numerical model and a 3-dimensional physical model. A hybrid element steady state linear monochromatic...
Numerical Modeling of Proposed Kawaihae Harbor, HI
The Kawaihae shallow-draft harbor site is located on the northwest coast of the island of Hawaii, HI. An entrance channel, turning basin, and breakwater currently exist at the harbor site....
Development of Detached Breakwater Design Criteria Using a Shoreline Response Model
An evaluation of beach response to detached breakwaters was conducted using the numerical shoreline response model GENESIS. Functional design parameters such as structure length, gap distance,...
The Application of Technology to Solving Practical Problems
In this paper, the roles of the scientist, technologist, engineer, and manager are discussed to place them in perspective. A distinction is made between the coastal engineer' and practicing...
A feasibility study for a Concrete Core Tomographer
This is a study of the feasibility of applying computer tomography in the study of concrete cores. A laboratory protocol is presented for testing concrete cores using a medical - grade...
Numerical Simulation of Dynamic Shear Transfer
This study was focused on the dynamic response of concrete interfaces under the effects of impulsive loads, and the relationship between the interface shear transfer and the response in...
Concrete Surface Characterization Using Optical Metrology
The displacement of the surface of a concrete specimen is measured as it cures using an optical method. This method, known as optical metrology, is one in which a line is projected onto...
Landfills: Anatomy of Automated Design
California's 360 acre Bee Canyon landfill (completed last year) sits amid a complicated network of narrow canyons with side slopes 300 ft high. As with most landfill projects,...
Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...
Adaptive and Parallel Methods for Nonlinear Solid Mechanics
The solution of nonlinear problems, which are of importance to industry and in scientific computations, requires increasing degrees of resolution. This high degree of resolution can be...
Analytical Studies on the Seismic Response of Lead Rubber Base Isolated Bridges
Highlights of a study related to the response of base isolated bridges are presented. Four different analytical models are developed and used to evaluate the response of base isolated...
Shoaling and Breaking of Random Wave Trains: Spectral Approaches
We describe recent efforts to develop a model to predict the evolution of the spectra of random ocean waves shoaling and breaking on a natural beach. A model based on the full Euler equations...
Nonlinear Shoaling and Impact of Waves on Coastal Structures
A two-dimensional fully nonlinear potential flow model is used to calculate shoaling of solitary and enoidal waves over a sloping bottom and interaction with submerged or emerged coastal...
Taylor-Galerkin Method for Wind Wave Propagation
Recently Taylor-Galerkin method has been used to successfully solve advection-dominated flow problems. This method performs quite well in reducing numerical dissipation and numerical dispersion...
On Distributed Processing Applications in Finite Element Analysis
Computer architectures may be classified by the relationship between their instruction and data streams (SISD, SIMD, MISD, MIMD) and the locality of memory (shared, local). Distributed...
Aspects of Parallel Processing in Reservoir Simulation
Vectorization techniques have proved to be extremely effective for large-scale reservoir simulations. Parallel capabilities hold even greater potential for these enormous problems. Domain...
