Gravity Dam Response Including Interaction Effects
The seismic response of 2D gravity dam-reservoir-foundation including the wave absorption effect along the reservoir bed is analyzed in frequency domain using substructure approach. The...

Interaction Between Waves and a Floating Body with Tension Legs
A boundary element method has been solved to the coupling problem of a two-dimensional tension leg platform interacting with a monochromatic wave train. In the boundary element calculation,...

Normal and Tangential Contact of Layered Spheres as Models of Joint Contact
The causes of cracking in degenerating cartilage are examined using analytical models of layered elastic spheres in normal and tangential contact. Vertical surface and deep radial cracks...

An Analytical Solution to Free Vibration Problems of Cross-ply Laminated Thin Doubly-curved Shells
Hitherto an unavailable analytical solution to the free vibration boundary value problems (b.v.ps.) of symmetric and antisymmetric cross-ply laminated thin doubly-curved shells of rectangular...

Penetration Tests in a Particulate Calibration Chamber
A numerical technique which couples discrete element method with boundary element method has been developed to simulate a two dimensional particulate assembly. Soil particles in the near...

Computer Simulations of Rapid Granular Flows Interacting with a Flat, Frictional Boundary
This paper compares the results of numerical simulations for the rapid, steady flow of identical spheres colliding with a flat frictional boundary with the recent predictions of Jenkins...

Numerical Simulation of Localization in Granular Materials
The structure of persistent shear bands in granular materials is investigated by numerically simulating an idealized assembly of two-dimensional particles. Flexible stress-controlled boundaries...

Alaska Coastal Management Program: Development of the Coastal Zone Boundary
The Coastal Zone Management Act of 1972 required participating states to identify areas subject to a state management program, or delineate a coastal zone boundary. Alaska's...

Reassessing the 3-Mile State/Federal Boundary
The allocation of state versus federal authority offshore is critical in determining the complexion and pace of OCS oil and gas development. Yet, recurring drilling moratoria indicate...

Fishery Management Implications of the U.S. Territorial Sea Extension
The Magnuson Fishery Conservation and Management Act of 1976 (MFCMA) declares a national standard that '[t]o the extent practicable, an individual stock of fish shall be managed...

Regional Ocean Resources Management
The fluid nature of the ocean environment and the mobility of living ocean resources place obvious limits on the ability of state and federal resource managers to effectively manage based...

Sea Level Rise and Maritime Boundaries: The Effect of Rising Sea Level on International Boundaries
This paper, jointly written by a lawyer and a coastal geomorphologist, will examine the possible responses at a legal level to the implications of global warming induced sea level rise...

Evidence for Eustatic Influence on Cenozoic Sedimentation of Coastal Washington and Oregon
Comparison of the absolute age boundaries of the West Coast biozonation with the Cenozoic global cycle chart indicates that 12 of the 15 zonal boundaries coincide with regressive sequence...

Mechanics of Cohesionless Sediment Transport in Coastal Waters
Conceptual mechanics-based models for sediment transport processes in steady and unsteady turbulent boundary layer flows are derived and discussed. To the extent possible the predictions...

Turbulence Measurements and Parameterizations
Bottom boundary layer and exchange models account for high frequency turbulence via Reynold's averaging and the most advanced closure formulations required by this averaging...

Suspended Sediment Load at Three Time Scales
Suspended sediment loads were examined at the three time scales of time-series-averaged, wave-by-wave and instantaneous during the wave cycle. Field measurements recorded on a natural...

The Vertical Structure of Cross-Shore Currents from Wind-Induced Setup
Most of the storm surge models presented in the literature are vertically averaged and calculate only the sea-surface elevation and mean flow. Whereas these models may be adequate for...

Regional Sediment Transport in the Coastal Boundary Layer of the Central Alaskan Beaufort Sea
The characteristics of regional sediment transport in the Central Alaskan Beaufort Sea Coastal Ocean are defined by sources, marine sediment dynamics, and areas of net sedimentation. These...

Fate of PCBs in Municipal-Sludge Amended Soil
This paper presents the preliminary results of a five-year field study of the fate of PCBs in soil that has been amended with municipal sewage sludge. A first-order model describes the...

Three Dimensional Modeling of Concrete Dams with Cracks Using Boundary Element Methods
Determining uplift pressure distributions in cracks in a concrete dam requires coupling between crack hydraulics and the stresses and displacements occurring in the rock and the concrete...
