Monitoring of Water Quality During I-664 Dredging
Construction of Interstate Highway I-664 across Hampton Roads involves extensive underwater work and consequent risk of lowered water quality. This paper described field monitoring procedures...
New Tools for Economic Evaluation of Channel Deepening Projects
The Institute for Water Resources has developed a data base to facilitate economic evaluation of channel deepening projects. After extensive research, data elements were selected from...
Beach Preservation by Means of Offshore Submerged Mound of Dredged Materials
The beach - sediment - dispersion- offshore or alongshore under the effect of waves and wave induced currents, and inland by wind action may cause a net deficit in sediment budget which...
Crunch Time for Airport Engineering
Airlines are attracting more passengers, but few new airports are being built. Existing airports are facing problems caused by this added load. One growing burden is aircraft noise at...
Maglev: Transportation for the 21st Century
If cities are to achieve their full potentials as economic and cultural centers, they must possess superior transportation systems. Ultra-silent, energy efficient, non-polluting magnetic...
Evaluation of Backshore Protection Techniques
The study site is Bethune Beach on the east coast of Florida in southern Volusia County which is experiencing severe and continued erosion problems. This shoreline erosion has become critical...
Nantucket's Broad Creek Opening
On September 20-21, 1961 a severe coastal storm, the remnant of hurricane Esther, formed a 1,200 foot wide, 20 foot deep opening in a barrier beach (Smith's Point at Broad...
Vertical Shelter From Hurricanes: Risk Perceptions and Politics
To reduce risks posed by high hurricane evacuation times, vertical shelters have been proposed. This paper presents a preliminary assessment of key decision makers' reactions...
A Railway Protection?Coastal Structures on Tyrrehenian Calabrian Coastline
The stretch of Calabrian coastline facing the Tyrrehenian Sea has for many years undergone severe erosion, exposing the Battipaglia-Reggio Calabria railtrack to the direct action of waves....
Assessment of Beach Nourishment Methodoliogies
Although artificial beach nourishment has become a common practice for mitigating beach erosion in the U. S. , it lacks clear rationales for achieving optimum benefits. Four recent large-volume...
Sand Rights, a Legal System to Protect the Shores of the Sea
The legal system of water rights in California is highly developed. So far, however, it has failed to recognize in any comprehensive fashion the importance of the sand which is transported...
Monitoring of Coastal Environment for its Management
The paper briefly explains the features of four coastal laboratories established along the southwest coast of India in 1980 and the data gathered by them during 1980-84. Four coastal piers...
Pollutant Transport Through Barriers
Methods of predicting contaminant transport through saturated and unsaturated clayey barriers are reviewed. Particular consideration is given to the relative importance of advection and...
Environmental Geotechnology & Tailings Reclamation
The Department of Energy is responsible, in terms of Federal Legislation, for remedial action work at 24 inactive uranium mill tailings piles in ten states. This paper describes the setting...
Flow and Mass Transport for Hazardous Waste Liners
Certain aspects of flow and contaminant migration of hazardous liquids through soils are addressed. A fine-grained soil and fluids commonly encountered in hazardous sites, were considered....
Modelling of Contaminant Transport in Clays Via Irreversible Thermodynamics
This study develops a model for the analysis and prediction of contaminant transport in soils using principles of irreversible thermodynamics. The developed model includes five parameters...
Quake Resistant Transport
An approach which begins by assessing the vulnerability of a transportation system's key components can help transportation engineers plan for and limit earthquake damage....
The Swedish Dioxin Moratorium
Municipal waste constitutes an energy resource but also an environmental problem. In Sweden emissions of dioxines from waste-to-energy plants have triggered a major debate on environmental...
The Dioxin Situation in West Germany
The public discussion in Germany of the 'dioxin problem' has recently become more rational than it was three years ago. Emotions and hard facts are in a balance...
