Estimation of Wind Fields for Coastal Modeling
Wind is an essential driving force for waves, circulation, and storm surge in coastal and estuarine areas. As with other horizontally 2-dimensional models, Corps of Engineers' (CE) numerical...

A Finite Element Model for Three-Dimensional Flows Along the West Coast of Vancouver Island
Extensive salinity and temperature measurements taken during June 1984 are used to calculate a three-dimensional density field for the west coast of Vancouver Island. Combining this field...

Hurricane Camille Shelf Wave Simulation Using a Numerical Ocean Circulation Model
The hurricane generated shelf waves for Hurricane Camille (1969) are studied using a three-dimensional, thermodynamical, primitive equation, ocean circulation model developed at Princeton...

Approximation of Convective Processes by Cyclic AOI Methods
Convective or advective processes play a role in many models for civil engineering applications. For example in transport equations, in hydrodynamic equations or wave energy equations....

Linearisation and Offshore Fatigue Reliability
In determining the force effects due to wave action on offshore structures it is conventional to use an equivalent linearisation to convert wave velocities to forces via Morison's equation....

Some Modeling and Analysis Techniques for Wave Propagation in Random Media
Some mathematical modeling techniques for the problem of wave propagation in randomly imperfect periodic medium are reviewed: multiscale formulation and random evolution modeling. These...

Wave Propagation in a Randomly Layered Medium
The authors briefly outline a problem discussed at length in a paper called Frequency content of randomly scattered signals, by M. Ash, W. Kohler, G. Papanicolaou, M Postel and B. White....

Wavefront Propagation in Random Granular Media
A very brief account is given of a stochastic method developed for analysis of transient waves propagating in one-dimensional random granular-type media. The method is suited to study...

Differential Motions in Sedimentary Valleys
The differential motions (strains), induced in sediment-filled valleys due to incident seismic waves, are investigated. The response of a two-dimensional model of an asymmetric wedge-shaped...

TLP Fatigue Due to Second-Order Springing
For offhsore oil production in water depths beyond 300-350 m, the tension leg platform (TLP) has become an increasingly popular design concept. The TLP is a floating structure with excess...

Nonlinear Diffraction of Random Waves by a Vertical Cylinder
In this study, nonlinear diffraction of random waves by a vertical uniform circular cylinder in deep water is analyzed. The incident wave field is represented by a stationary random process,...

A Non-Gaussian Fatigue Model for Offshore Structures
Fatigue damage accumulation in members of offshore structures can be affected by various aspects of the non-Gaussian response stress time history induced by the nonlinear/non-Gaussian...

Pile Installation and Testing at Ningbo Port, China
As part of an ambitious development program at the Port of Ningbo, the People's Republic of China constructed a 694 m (2277 ft) long offshore pier structure to provide a container berth...

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...

Results of a Monitoring Program of Moored Ship Response to Gravity and Infragravity Waves
An automated monitoring system was designed and operated at a coal terminal in Los Angeles Harbor, and a container terminal in Long Beach Harbor, to obtain the complete six degree-of-freedom...

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...

A Chance Constrained Optimization Model Using Kinematic Wave Routing for Stormwater Infrastructure Rehabilitation
A chance constrained optimization model is presented to determine efficient long-term replacement strategies for segments of stormwater drainage systems. The model is multiobjective in...

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....

Innovations for NDT of Concrete Structures
The proposed paper presents three recent innovations for sonic and ultrasonic Non-Destructive Testing (NDT) of concrete structures which greatly increase the utility and speed of many...
