Non-Intrusive Rayleigh Wave Measurement System for Soil Profiling in Ports
Accurate shear wave velocity profiles have been long recognized as essential data to evaluate the dynamic response of soil deposits and soil-structure interaction under earthquake and...

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...

Barbers Point Harbor: A Unique Solution for Port Upgrade
A remote-controlled model of a C9 containership was used to evaluate the navigability of existing harbor and entrance channel conditions in a three-dimensional physical model of Barbers...

Development of Storage Demand Relation for Reservoirs?A Probabilistic Approach
This paper presents a practical method for developing storage-demand relation for reservoirs by a probability analysis of the stream flow data. The method was employed by the author for...

Successful High Traffic Chip Seal Construction
Chip seal coats are used to extend pavement service life by reducing water and air infiltration and improving skid resistance. Application of chip seals is usually limited to low-traffic...

A Theoretical Approach to Characterize Reinforced Concrete Using Stress Waves
Although advances in nondestructive evaluation of structural concrete have been made, the ultrasonic determination of the placement of steel reinforcement in concrete remains difficult....

A Numerical Study of Kinematics of Nonlinear Water Waves in Three Dimensions
We present a new method for analyzing the kinematics of nonlinear water waves in a three-dimensional domain. This method is based on our extension and generalization of the mixed-Eulerian-Lagrangian...

Probability of Wave Force on Horizontal Members
This study is motivated by the works of Isaacson and Subbiah (1990) to evaluate the vertical wave force on a rigid horizontal member located in the vicinity of still water level with its...

Reliable Design-Wave Force Predictions for Seabed Pipelines
The results of three separate field research projects have been pulled together to provide a design formula for maximum wave-induced horizontal force on a submarine pipe. This broadly-applicable...

Static Wave Force Procedure for Platform Design
Since results from the Ocean Test Structure were presented at Civil Engineering in the Oceans IV in 1979, there have been numerous laboratory experiments and a few full-scale measurements...

Recent Wave Kinematics Experimental Studies
Kinematics in the near surface region of water waves have been measured with a laser Doppler anemometer in the laboratory. The major results of these recent wave kinematics measurements...

Wave Slamming on a Horizontal Circular Cylinder
The present paper describes an experimental study of the wave slamming force on a horizontal circular cylinder located near the free surface. The vertical force on a cylinder and the corresponding...

Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...

Thermal Strain Behaviour of Clays Cooled to Cryogenic Temperatures
The thermal expansion behaviour of two different types of clays (Boom clay from Belgium and a pure kaolinite-water paste) has been studied in a temperature range from +20? to -150?C (LNG...

Ice Jam Configuration: Second Generation Model
An early model of ice jam configuration in wide, prismatic channels is generalized for applications to natural streams. Test runs are carried out to illustrate model performance and study...

Heat Exchange at the Ice/Water Interface on Flowing Water
Any time the water flowing under an ice cover has a temperature above freezing, there is an exchange of heat between the water and the ice. Earlier work by Ashton and others provided adequate...

Effective Pressures Measured During Indentation Tests in Freshwater Ice
Indentation tests were conducted by pushing flat, vertical indentors of two different widths (50 and 100 mm) against the edges of floating, freshwater ice at different velocities (0.6-150...

Spray and Ice Measurement Instrumentation for Ships
Bow slamming is the primary water delivery mechanism for ship superstructure icing. Spray flux is largely dependent upon hull dynamics, and cannot be computed numerically with current...

The USACRREL Underwater Frazil Ice Detector
A modified underwater frazil ice detector has been developed at USACRREL. This detector, which operates remotely, can automatically start deicing procedures and alert operators to the...

Preliminary National Evaluations of CO2 Emission Controls
Under the aegis of the International Energy Agency, several countries have begun making comparable studies of the cost-effectiveness of various measures to reduce emissions of carbon dioxide...
