Societal-Individual Risks for Hazmat Transport
Risks associated with the transport of hazardous materials by truck and rail are viewed from two perspectives: society in general and the individual residing adjacent to the route. A range...

GIS Risk Analysis of Hazardous Materials Transport
The Geographic Information System (GIS) was used to assess the risks and vulnerability of transporting hazardous materials and wastes on the Arizona highway system. This paper discusses...

StateGEN/StateNET and DOT Guidelines: Tools for Highway Routing of Hazardous Materials
Under the sponsorship of the U.S. Department of Energy Office, of Defense Programs, Sandia National Laboratories' Transportation Technology Center has developed computerized...

Computer-Assisted Risk Assessment of Dangerous Goods Transportation for Haute-Normandie
To assess the 'best' routes for the transport of dangerous goods in an area of 600 km2 in France, software based on a geographical information system to manage,...

An Overview of Hurricane Damage to Military Facilities and the Storm Recovery Role Played by the Southern Division Naval Facilities Engineering Command
Hurricane Hugo struck a major blow to the military's shore facilities at Charleston, SC and Sumter, SC. The Air Force Base at Myrtle Beach, SC suffered only minor damage....

A Post Hurricane Hugo Transportation Study
Hurricane Hugo will remain in the minds of South Carolinians for many years to come. This hurricane attracted most of the world's attention in 1989 as it devastated every...

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...

Management of Sandy Inlets: Coastal and Environmental Engineering Imperatives
Management of sandy tidal inlets is required for maintenance of navigable channels and control of beach erosion. Management elements essentially entail 'resharing'...

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...

Hydrodynamic Behavior of Cohesive Sediments in Turbulent Flow
To meet both engineering and basic research requirements, a series of experiments on the deposition of cohesive soil were conducted in an annular rotating fiberglass channel-ring system...

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...

Estuarine Tropical Forcing Functions: The Palizada River Delta (Southern Gulf of Mexico), a Case Study
The geomorphological characteristics of the fluvial - deltaic - lagoon - estuarine system of Palizada River (FDLESPR) in the southern Gulf of Mexico, allows the interaction of several...

An Offshore Borehole Mining Experiment: Its Operational and Environmental Implications
The Continental Shelf Division of the Marine Minerals Technology Center (MMTC), conducted a miniborehole mining experiment offshore Georgia in June 1990. A remote placer drill developed...

A Study of the Impact of the Dumping of Spoil on Beach Processes
The amenity value of beaches along the North East coast of England is reduced because of the continuing practice of dumping colliery spoil directly onto the beaches for dispersal by the...

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...

Environmental Impact on Sepetiba Beach
This paper describes the erosive and sedimentary processes which have been causing damage to the most important beach on Sepetiba Bay in Brazil. Remote sensing techniques and data obtained...

Coastal Erosion in Ghana: Causes, Patterns, Research Needs and Possible Solutions
The pattern of coastal erosion in Ghana is described. The causes for spatial differences in the erosional rates on the shoreline are identified as coming from a combination of natural...

Facing the Challenge of Rapid Socio-Political Change and Its Environmental Consequences for the Coastal Zone in Southern Africa: An Abridged Paper
The coastal zone of southern Africa is an asset of inestimable value. But the finite resources of this coast are subject to the demands of a rapidly growing population. Moreover much of...

A Coastal Action Strategy for Southern Africa
The rapidly changing demands and circumstances in southern Africa are offering exciting new challenges in coastal zone management (CZM) and have highlighted the urgent need for effective...

Coastal Dune Blowouts?Dynamics and Management Implications
New approaches to coastal dune management have been advocated recently, including dune grading and dune destabilization. A management concern in the case of destabilization involves the...
