A Centrifuge and Analytical Study to Evaluate Suction Caissons for TLP Applications in the Gulf of Mexico
This paper documents the results of a combined centrifuge and analytical study to evaluate the behavior of steel suction caissons under loading and soil conditions typical of deepwater...
Transmitted Swelling Pressures on Retaining Structures
The main objectives of this paper are to describe a finite element model to simulate the lateral swelling behavior of expansive soils as a function of soil suction change in the soil domain...
Tying Up The Artery
After six years, preliminary design is almost complete on one of the nation's largest, and most complicated, public works project, the Boston Central Artery project. At an...
Physical Model Testing of Broken Armor Stone
Cracking, breaking into two or more pieces, flaking, crumbling, and abrading may reduce an armor stone to a size where wave action can remove it from the structure causing a local instability....
Stability of Rock Armour Under Random Wave Attack: Performance of Non-Standard Rock Shapes and Gradings
Quarried rock is frequently used to protect coastal and shoreline structures against wave attack. Armour rock specifications generally exclude rock that is rounded or tabular, and gradings...
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...
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...
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...
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...
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...
Energy Dissipation Characteristics of Rubber Cylinders
A simplified procedure for scaling the energy absorption characteristics of rubber cylinders during high speed impact is presented. Static and dynamic tests of scale model and full size...
Rate-Dependent Plasticity Representation for Energy-Absorbing Materials
A three dimensional rate-dependent plasticity constitutive model is developed for rigid polyurethane foams. In the model, the material is decomposed into skeleton and solid matrix from...
