Pipeline Storm Behavior on Clay Soils
A series of transverse wave loading tests was conducted on a specially mounted section of pipe in a sediment-filled tank, to investigate the stability of unburied submarine pipelines under...
The SIMBAT Software Package for Stochastic Interpolation of Ocean Wave Kinematics as an Aid in the Engineering Design of Large Floating Structures
Geostatistical techniques of nonconditional and conditional simulation are used in a new public domain computer software package, named SIMBAT, to stochastically interpolate ocean wave...
Recent Wave Kinematics Experimental Studies
Kinematics in the near surface region of water waves have been measured with a laser Doppler anemometer in the laboratory. The major results of these recent wave kinematics measurements...
Spectral and Statistical Characteristics of Wind Waves Off Canary Islands
Wave climate around Canary Islands is studied by means of statistical and spectral techniques. Maximum Entropy Method is used for obtaining the spectral density function. Autocorrelation...
Wave Slamming on a Horizontal Circular Cylinder
The present paper describes an experimental study of the wave slamming force on a horizontal circular cylinder located near the free surface. The vertical force on a cylinder and the corresponding...
Hydraulic Design of Offshore Breakwater in Sergipe, Brazil
A Petrobras (Petroleo Brasileiro S.A.) marine terminal was recently constructed in Sergipe, Brazil (Figure 1). The offshore breakwater was initially designed in a conventional way, but...
Stability of Accropode(R) and Comparison with Parallelepipedic Block
This paper describes the tests which were performed on physical models with irregular waves, to determine the hydraulic stability of the Accropode(R)...
Experimental Research on Groyne Stability Under Very Oblique Wave Action
Most of the experimental research concerning the stability of coastal structures is focused on normal wave incidence. However, many of these structures are subject to waves which run predominantly...
Mobile-Bed Physical Model Tests for the 1992 Olympic Harbour
The undistorted physical model is described which allowed the measurement of the wave induced velocity field along the main breakwater, and also in Somorrostro Beach (Barcelona). The current...
Dynamic Design of Deepwater Bottom-Founded Towers
This paper traces the development of dynamic design techniques for deepwater bottom-founded towers by the following: the classification of bottom-founded towers as either `stiff' or `compliant';...
Equivalent Statistical Quadratization of Nonlinear Hydrodynamic Loads on TLPs
In this paper, a new method is proposed for the expansion of nonlinear drag forces expressed in terms of multivariate Hermite polynomials correct up to the second-order. The drag force...
Dynamic Response Characteristics of Jack-Up Drilling Units
The effects of five parameters on the dynamic amplification of the global base shear on a deep water jack-up drilling unit were analyzed using a time domain nonlinear model. The five parameters...
A Laboratory Study of Shock Waves in Frozen Soil
This work has focused on two aspects of dynamic behavior of frozen soil: first, on the shock pressure attenuation, and second, on the shock Hugoniot. The use of long bars of frozen soil...
Future Technology for Disbonding Snow and Ice from Pavements
Current techniques to remove ice and compacted snow from pavement surfaces are costly because they needlessly crush or melt most of the ice layer. Also, in many cases they do not accomplish...
Correlation of Hydraulic Conductivity and Sonic Velocity in Water-Saturated Tuff
A laboratory study was conducted to investigate the correlation of hydraulic and sonic properties of water-saturated tuff. The hydraulic test used a new rock block testing machine, which...
Nondestructive Testing Using Borehole and Surface Seismic Techniques to Evaluate Rock Mass Damage Zones
A suite of seismic tests was performed at the U12g tunnel at the Nevada Test Site. The methods include borehole (crosshole and downhole) and surface (Rayleigh wave and refraction) tests....
Prediction of Runoff-Evapotranspiration to Estimate Leachate Generation in a Landfill
The fraction of precipitation that remains after runoff and surface water evaporation, enters into the solid waste landfill and generates leachate flow at the bottom. A part of the infiltration...
Wave Motion in Aerated Rubble Mounds
Experimental investigations were undertaken to study the effect of air entrainment on wave motion in rubble mounds. The study is aimed at the understanding of the processes associated...
Model Mania in Urban Hydrology: Present Dilemmas
A recent ASCE Task Committee on microcomputer software in urban hydrology has just completed its inventory of 40 software packages available at modest cost to the urban drainage engineer....
Interaction of Elastic Waves with Axisymmetric Cavities in a Half Space: A Combined Finite Element-Boundary Integral Approach
A hybrid numerical method is presented to investigate the interaction of elastic waves with axisymmetric cavities on the surface of a half space. In this method the near field which consists...
