Three-Dimensional Circulation Modeling of the Coastal and Ocean Environments
Incursion of the loop current, a meandering feature of Gulf of Mexico large-scale circulation, may produce large hydrodynamic forces on the offshore structures. The present study is to...

A New Concrete Armor Unit for Breakwaters: The Beta Block
The aim of this paper, is to present a new artificial block for the protection of breakwaters. This armor unit, named BETA, has been designed and tested in the Coasts and Harbors Studies...

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)...

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...

Piles Under Dynamic Loads
This proceedings, Piles Under Dynamic Loads, consists of papers that try to identify the state of practice in the analysis and design of pile...

Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...

Civil Engineering in the Oceans V
This proceedings is a collection of technical papers presented at Civil Engineering in the Oceans V (CEO V) specialty conference held at College Station, Texas on November 2-5, 1992. Initiated...

Dynamic Wind Loads
This chapter is concerned with the motions of cable stayed bridges that arise as a result of wind action. The aerodynamic phenomena that must be considered are vortex shedding, torsional...

MUT1D: User-Friendly One-Dimensional Thermal Model
MUT1D is a microcomputer-based heat conduction model which uses implicit finite difference techniques to determine the thermal regime and track the movement of the phase change front in...

Computer Predictions of Thaw Beneath Gravel Embankments on Warm Permafrost
A computer model was used to simulate the freeze-thaw effects of gravel embankments on warm permafrost typical of south-central Alaska using a one-dimensional finite-difference code, FREZ1D....

Impact of Cold Weather on Building Construction Scheduling
Weather impact on a building construction schedule is often significant in cold regions. Most deterministic scheduling methods are unable to directly account for the effects of weather...

Ice Jam Configuration: Second Generation Model
An early model of ice jam configuration in wide, prismatic channels is generalized for applications to natural streams. Test runs are carried out to illustrate model performance and study...

Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...

A Conceptual Model for Vertical Frazil Distribution in Turbulent Flows
A conceptual model is presented for the evolution of frazil over depth in a turbulent flow. The net upward migration due to buoyancy of the frazil is opposed by intermittent mixing induced...

A Two-Dimensional Surface Drift Model for River Ice
A two-dimensional surface drift model for river ice with low ice discharge conditions is presented. The model is applied to the Grass Island Pool area of the Niagara River and compared...

River Ice Cover Cracking for Various Boundary Conditions
The breakup of river ice covers is commonly initiated by the formation of cracks parallel to river banks. These cracks usually result from a change in the water level due to a rapid rising...
