Relocating a 54-Inch Diameter Force Main without Interrupting Wastewater Flow
The City of Tampa, Florida, was faced with the challenge of relocating three segments of an old 1372 mm (54-in.) diameter reinforced concrete pipe force main, totaling nearly a mile in...

The Application of 3 Dimensional Geographic Information Systems in Geotechnical Earthquake Engineering
The requirements and needs of Geographical Information Systems (GIS) in geotechnical earthquake engineering are described, and the use of such system in New Zealand is discussed. We have...

Video Modeling: A New Paradigm for Reproducing Complex Engineering Artifacts on Computer
This paper introduces a novel approach for automatically creating accurate computer models of existing, physical artifacts. Based on the projected silhouettes of the object, when viewed...

A New Three-Dimensional Modeling Technique for Studying Porous Media
A new three-dimensional technique for modeling the micro-structure of porous media is proposed. On the basis of measurements of characteristics made using thin sections of porous media...

Image Analysis for Interparticle Contact Modeling
Two dimensional photoelastic elements (disks or ellipses) are used as models for studying granular material behavior. The required observations include accurate continuous measurements...

3-D Deformation Analysis of Pile Groups During Wave Loading
Deformation predictions of pile group supporting one leg of Magnus platform were conducted using the 3-D nonlinear computer program SPLICE (Structure/Pile/Soil Interaction Analysis) and...

Permeability Determination for Unsaturated Soils
A reliable approach for the determination of the soil hydraulic conductivity function relies on the parameter estimation solution approach in which heterogeneous state of saturation within...

Transit Times Through Compacted Clay Liners
Transit time, or time taken by waste liquid to move through the thickness of the liner, is a short-term performance parameter which can be used to determine the necessary liner thickness....

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...

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...

A Design Manual for Coastal Fluidization Systems
This paper summarizes a recently completed design manual on fluidization systems to manage sand in the coastal environment for sand bypassing at inlets and harbor mouths and for creating...

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...

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...

Wave Interaction with Fluid Mud in Rectangular Trench
Wave interaction with fluid mud in a rectangular trench is studied theoretically based on small-amplitude wave theory. The problem was formulated using the Voigt model for an viscoelastic...

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...

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...

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...
