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...
Erosion of the Slopes of Gold Tailings Dams
A study has been made of rates of erosion from the slopes of gold-residue dams in the South African Highveld region. Data is available for two years at this time and conclusions must therefore...
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....
Embankment Over Fly Ash Pond at Portsmouth Power Station
The fly ash and bottom ash sediments from the Portsmouth Power Station in Portsmouth, Virginia were being sluiced into a 39 acre diked ash pond near the plant. The plant was about to convert...
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....
Coastal Sediments
The two-volume Proceedings of Coastal Sediments '87 contain more than 150 full papers delivered at a specialty technical conference of the American Society of Civil Engineers...
Aids for the Hazard Classification of Small Dams
The last few years have seen a large growth in the tools available to the engineer to better determine the risk of failure in earth dams. One of the models developed is the National Weather...
Dam Safety Improvements for Tolt River Dam
Studies were performed to identify measures to improve the safety of the project under earthquake and extreme flood conditions while permitting the owner to store additional water under...
