Landslide-Generated Wave Studies
A serious safety of dams problem is associated with large masses of rock and debris plunging into lakes and causing damaging water waves. This concern prompted the Bureau of Reclamation...

Coastal Protection Guidelines, Orange County, GA
As a result of coastal storms in the past several years the County of Orange (California) incurred large and unanticipated costs in providing emergency protection for private shorefront...

Wave Height Distribution in the Coupled Harbor
Wave height in a harbor sheltered by a breakwater is studied by numerical simulation and experiment. The coupled harbor, attained by setting up double arm breakwaters, was adopted as the...

Feasibility Study of Flood Control for the Maumee River in Allen County, Indiana
In March, 1982 the Maumee River overtopped its banks flooding parts of the City of Fort Wayne and unincorporated areas in Allen County, Indiana. The estimated damage to the area was about...

Laboratory Model Studies of Flood Wave Propagation
Laboratory investigations of unsteady free-surface flow with various combinations of channel and flood conditions were performed. A 72 ft (21. 9 m) long tilting flume was modified to make...

Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...

Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...

Seismic Interaction Among Numerous Masses Founded on a Viscoelastic Stratum
The steady-state harmonic response of systems comprising numerous masses resting on a homogeneous, viscoelastic stratum with hysteretic damping is studied. The stratum, bearing on a rigid...

Vibration Isolation of Structures From Surface Waves in Layered Soil
This work deals with the problem of isolation of structures from ground transmitted surface waves generated by machine foundations. The isolation is accomplished by means of rectangular...

Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...

RCC: A Dam Rehab Solution Unearthed
Roller compacted concrete (RCC) is fast becoming a popular material for the rehabilitation of existing dams. Several dams have already been rehabilitated using RCC, and several more RCC...

Some Recent Advances in Automatic Mesh Generation
The establishment of automated finite element modeling procedures must begin with the development of automatic mesh generators capable of producing a valid finite element mesh for any...

Modern Methods for Automatic FE Mesh Generation
An overview of the various Finite Element mesh generation techniques is presented. Since most automatic FE Mesh Generation techniques read in geometry of the object and create meshes on...

A Mesh Generator for the Modeling of Rock Discontinuities
The need to characterize a rock mass by collecting field data is receiving more and more emphasis as larger, more ambitious underground structures are being built. Yet there is a need...

Automating Three-Dimensional Finite Element Mesh Generation
A number of important advances and contributions to the topic of computer aided finite element mesh generation have been made by the Mathematics Department at the General Motors Research...

Hierarchical Substructuring for Adaptive Analysis
An algorithm for the automatic generation, from solid models, of finite element meshes organized as spatially addressable quaternary trees (for 2-D analysis) or octal trees (for 3-D analysis)...

Wind Effects on Compliant Offshore Structures
In recent years modern experimental and analytical techniques for estimating wind effects have increasingly been applied to compliant offshore structures. The six papers included in this...

Modern Methods for Automating Finite Element Mesh Generation
The collection of finite elements composing the finite element model is the finite element mesh. The five papers in this book describe computer aided methods for generating finite elements...

A Contractor Looks at Slope Protection for Arctic Offshore Artificial Islands
Some thirty artificial gravel islands for oil and gas drilling/production have been built in the Beaufort Sea since early 70's. Protection of slopes of the islands and causeways...

Santa Fe's Mobile Arctic Drilling Barge
There is a need for mobile units that can operate year-round in shallow Alaskan waters south of the Bering Strait for exploratory drilling and/or early production. Santa Fe has completed...
