Evolution of Nonlinear Long Waves After Interacting with a Breakwater
Three-dimensional evolution of nonlinear long waves after interacting with a straight thin breakwater is investigated in this paper. The primary interest is to apply a weakly nonlinear...
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,...
Numerical Simulation of Dam-Breaking Waves
Recently, as a high-resolution numerical technique, the Total Variation Diminishing (TVD) method is applied to Aerodynamic shock problems successfully. In this paper, a Total Variation...
Comparative Time Domain Analysis of Some Available Analytical and Empirical Expressions for the Spatial Variability of Seismic Ground Motions
Simulations in space and time based on models for the spatial variability of seismic ground motions are generated. Displacement time histories are simulated through the spectral representation...
Time-Delayed Control of Nondispersive Continuous Systems
This paper deals with the noncollocated, time-delayed active point control of continuous systems. It considers systems of finite spatial extent which can be modelled by the undamped wave...
In Situ Determination of Smith Soil Model Parameters for Wave Equation Analysis
A methodology for in situ determination of Smith soil model parameters for wave equation analysis is presented. The method uses a small-rod penetration test in conjunction with CAPWAPC...
Measurement of Subsurface, Deep Foundation and Slab/Subgrade Conditions with In Situ Seismic, Sonic and Vibration Methods
Case histories are presented to illustrate quality assurance and forensic applications of nondestructive testing and evaluation (NDT&E) methods for in situ investigation of subsurface...
Wave Equation Modelling of the SPT
The stress wave propagation in the Standard Penetration Test (SPT) is described in this paper. It is shown that the SPT is a complex dynamic system and that both force and motion measurements...
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...
Meteorological Aspects of Hurricane Hugo
Despite recent improvements in the accuracy of hurricane forecasting at a rate of about one-half to one percent per-year over the past decade, the population growth in coastal mainland...
Performance of Building Resistance to Water, Waves and Erosion
Water damage to buildings due to Hugo was widespread and severe throughout low-lying coastal areas. Flood insurance claim payments have already exceeded $350 million, the largest payout...
Debris Removal and Channel Shoaling
Hurricane Hugo was one of the worst storms of the century to strike the east coast of the United States. The storm tracked a northwesterly course approximately 11:30 P.M. on Sep. 21, 1989....
Development of Shallow Draft Harbor Design Criteria
One of many U.S. Army Corps of Engineer (USACE) missions is the construction and maintenance of shallow-draft coastal ports and harbors. Current practices for shallow-draft harbor design...
Are Timber Seawalls that Fail, Cost Effective??Seacliff State Beach Santa Cruz County, California
Proposed reconstruction of a major portion of a 5,100-foot long timber seawall at Seacliff State Beach in Santa Cruz County, California, in 1984, became a major controversy because of...
Assessment of the Nearshore Zone at St. Marys Inlet, Florida
St. Marys Inlet connects Cumberland Sound from the Atlantic Ocean and actually forms the coastline border between Georgia and Florida. Drumstick shaped barriers are located to the north...
An Offshore Seismic Data Network
Response to environmental forces is a major performance consideration in designing offshore oil and gas facilities. Climatic and oceanographic data are available for most offshore sites....
A Piston-Type Nonlinear Wavemaker Theory
In this paper, the small-amplitude surface waves produced by a piston-type nonlinear porous wavemaker in an infinitely and a semi-infinitely long channel are studied. Analytical solution...
Model Comparisons of Harbor Wave Response
Physical and numerical model tests were conducted for an idealized, flat-bottom rectangular harbor, entrance channel, and nearshore bathymetry. Bathymetry of the entrance channel and offshore...
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....
