Use of Computers for Soil and Rock Testing
The Bureau of Reclamation's central geotechnical laboratory in Denver, Colorado, routinely uses computers and associated electronic measurement devices for data acquisition,...

Use of Bar Code Technology to Simplify Sieve Analysis Data Acquisition
A system has been developed at the U.S. Army Corps of Engineers Ohio River Division Geotechnical Engineering Laboratory using bar codes and a computer coupled balance to aid in data collection...

Data Acquisition and Test Control in the Laboratory
With the progressive development of microcomputer technology, microcomputer based data acquisition systems have become an indispensable tool in the soil mechanics laboratory. This paper...

Spatial Variation in Liquefaction Risk Assessment
Basic concepts and methods of random field theory, needed to characterize 'distributed disordered systems', are reviewed and applied to a soil liquefaction case...

Lessons Learned by the News Media
The paper summarizes a few things learned from the news media's experience in Hurricane Hugo and which they will try to do differently the next time. These include: simulcasting...

The Use of Computer Mapping to Establish Historical Erosion Rates and Coastal Cosntruction Setbacks in New Jersey
New Jersey's Rules on Coastal Zone Management define coastal policies which guide public decisions about significant proposed development and management of resources of New Jersey's coastal...

The Acqisition of Remotely Sensed Sargassum Information on Daya Bay
The nuclear power plant on Daya Bay is the largest nuclear power plant under construction in China. In order to obtain reliable data about the possibility of blocking of the water intake...

Numerical Modeling of Storm-Induced Beach Erosion, Folly Beach, South Carolina, Beach Fill Alternatives
The U.S. Army Engineer District, Charleston (SAC), is developing a National Economic Development (NED) Plan for providing northeaster and hurricane storm protection for the municipality...

Controlling Parameters on Littoral Transport and Coastline Development
An extension to the one-line approach to coastline development modelling is presented in the light of the major parameters influencing the longshore sediment transport processes. The model...

Organic Compound Modelling in Tidal Waters
For a case study, different types of models of the entire harbor of Hamburg were developed. Some of these models are useful for describing oil transport in the case of an accident (e.g.,...

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...

The Width of the New Artificial Channel of the Port of Lisbon?An Application of the SIMNAV Simulation Model
The study of the width of the new artificial channel for the entrance of the port of Lisbon (in the Tagus estuary), which will allow the passage of fourth generation container ships, is...

Port Layout Optimization for Large Bulk Carriers in a Strong Tidal Currents Site
To provide the sheltering conditions of Ponta da Madeira Terminal (TPM) in Sao Marcos Bay, in Sao Luis, Brasil, two rubble mound groins were designed and constructed according to hydraulic...

Geotechnical Failure of Revetments
A calculation method is developed to analyse the stability of a granular subsoil underneath a revetment under wave attack. This method leads to a minimum revetment weight per square meter...

Rehabilitation of Vertical Thin-Walled Breakwater
Physical hydraulic model tests were conducted to measure wave transmission and force characteristics of a partial vertical thin-walled breakwater. Tests were run for the breakwater in...

Field and Numerical Investigations on Siltation Mechanism in Kumamoto Port
Synthetic investigations on siltation mechanism in Kumamoto Port were carried out by field observations, laboratory tests, and numerical simulations. Natural conditions such as tides,...

A Reef Conservation Project Involving Sport Divers in Singapore
The limited extent of Singapore's territorial waters places almost all the area within the boundary of its harbours. This includes many of the fringing and patch reefs associated...

Numerical Simulation of Larval Dispersal and Recruitment to Coral Reefs from the Mainstream Water Circulation
Coral reef systems, such as the Great Barrier Reef, Australia, are characterized by populations of fish and invertebrates that, mostly, produce offspring as pelagic larvae. Although some...

Modeling of Salt-Water Intrusion in River Mouth Region
By considering the fresh water and salt water as different phases in a two-phase flow system, a set of equations are given for describing the salt-water intrusion as well as the mixing...

3-D Modelling of Suspended Sediment Transport
A three-dimensional finite difference model has been developed for the numerical simulation of the physical process of horizontal and vertical convection, horizontal and vertical diffusion...
