Biomechanics of Local Articular Incongruities
Abnormalities of intra-articular contact near sites of local surface incongruity are frequently associated with secondary osteoarthrosis. We here review a series of experimental and computational...
Vibration of Plates with Corner Stress Singularities
A method of analysis is presented to determine the free vibration frequencies of plates having corner stress singularities. Displacements are assumed in the form of polynomials, and corner...
Frictionless Contact of Composite Laminates
An approximate solution technique for determination of contact stress distribution under a curved, rigid punch indenting an arbitrary laminated composite plate is outlined. The individual...
Factors Affecting the Incremental Stiffness of Particle Assemblies
A simple numerical experiment was performed on an assembly of densely packed spheres in order to investigate the factors that affect an assembly's incremental stiffness. The...
Monte Carlo Simulations of the Dynamic Response of Pile Groups
A study is presented on the effect of variations of relevant parameters within a pile group on the vertical dynamic response of the group. These parameters include the shear wave velocity...
Data Base of Seismic Body Wave Velocities and Geotechnical Properties
A data base of seismic velocities measured in soils and standard geotechnical engineering material properties has been established at the U.S. Army Engineer Waterways Experiment Station...
Sponge Distribution at Arraial do Cabo, SE Brazil
Spatial and temporal distribution of shallow water sponges were studied on southeastern Brazilian rocky coasts by means of qualitative and quantitative samples made by SCUBA diving. Cluster...
Method for Treating the Stochastic Nature of Water Level and Wave Climate in Determining Economically Optimal Channel Depth at Small-Boat Harbors
Engineering and economic aspects of channel depth at small-boat harbors is discussed. The concept of wave-adjusted water level is shown to be important to specifying channel bottom elevation....
Marsh Erosion by Wave Action
This paper summarizes an analysis of salt marsh shoreline erosion, wind velocities and wave energy in Corte Madera Bay during an abnormally calm period in 1989. Winds during the study...
Importance of the Surf Zone of Exposed Sandy Beaches for the Development of Juvenile
Sandy beaches dominate most of the tropical and temperate coastlines. Studies of nearshore ichthyofauna, in different regions of the world, have revealed the frequent occurrence of juvenile...
Ecological Studies at Espirito Santo Bay?Brazil Zooplankton Communities
Espirito Santo Bay is a coastal-tropical system, with strong water renovation cycle, which in turn adequate conditions to the development of many planktonic species (Bonecker et al., 1989)....
Saline Intrusion in Marine Effluent Outfalls
The paper presents an experimental investigation of saline intrusion in long sea outfalls. This intrusion is caused by the influx of sea water that may occur during periods of low discharge,...
An Overview of Chemical Contaminants Throughout the Coastal and Estuarine United States
Informed decisions on the use and management of the nation's resources requires convenient access to current and reliable information. Since 1984, the National Oceanic and...
Basic Physical Models in Sediment Transport
Basic particle dynamics and cellular automata micromodels of clastic sediments are described and applications are illustrated in the areas of aeolian saltation, bedload transport, size...
Infragravity Driven Suspended Sediment Transport in the Swash, Inner and Outer-Surf Zone
Nearbed suspended sediment concentration and velocity measurements from 3 field sites in the mid-outer surf zone (low energy), inner surf zone (high energy) and swash (high energy) are...
Sediment Transport by Strong Wave-Plus-Current Flows
A prediction formula is derived for the suspended sediment transport rate in coastal regions when the current speed and/or wave orbital velocity is large. It is based on generalised forms...
Cross-Shore Sediment Transport Modelling and Comparison with Tests at Prototype Scale
A series of prototype scale laboratory experiments have been performed at the Large Wave Channel (GWK) in Hanover to investigate the process of sediment transport over a horizontal bed...
Estimation of Overwash Bore Velocities Using Video Techniques
Overwash data were collected at a site on the Isles Dernieres, LA barrier island chain during Hurricane Gilbert in September 1988. A video technique was applied that allowed the quantification...
Quantifying Mud Exchange Between the Eastern Scheldt Tidal Basin and the North Sea
Net transport of sediment < 53 ?m through the mouth of the Eastern Scheldt has been quantified. Combination of data on spatial and temporal variability shows that incertainties...
Computer Simulation of Shore-Normal Variations in Sediment Size
A computer simulation model is presented which is designed to predict the selective shore-normal sorting of grain sizes in the nearshore environment. The model simulates wave shoaling,...
