Predictive Techniques for Marina Water Quality Assessment
The construction of new marinas in coastal areas requires as assessment of potential impacts on water quality as a part of the permit process. This paper summarizes a study sponsored by...
Conflicts Between Pleasure Boats and Fishing Boats at Marinas in Japan
At present, some half of the marinas operating in Japan have conflicts of various kinds relating to the navigation of pleasure boats. This study discusses the findings of a study on 365...
Lessons from Hurricane Hugo: Recommendations for Marina Operation and Design
Hurricanes are not new to South Carolina, but with the recent development of the coast, many new and unseasoned boaters have located in the area. Since Hurricane Hazel in 1954, South Carolina...
Aircraft Traffic Mix Analysis: Damage Factors and Coefficients
Historically, traffic mix analyses have been based upon the use of the critical or most damaging aircraft. The damage effects of other aircraft are either ignored or empirically incorporated...
Landing on Frictionless Surfaces
Who in his right mind would deliberately land an airplane on a frictionless surface? Unfortunately, professional pilots occasionally encounter situations where the friction between rubber...
Alternative Airfield Pavement Quality Control
In recent years, the cost of maintaining quality control during airfield construction projects has concerned airport operators and engineers alike. This paper addresses the possibilities...
Geotechnology: An Environment of Change
Today's contaminated materials�soil and water�have been investigated and analyzed by geotechnical engineers for a long time. No other branch of engineering is better positioned,...
Pumping Oil, Treating Soil
Oil was discovered on hilltop land in Signal Hill, Calif., in 1921, setting off one of the most wild land rushes the state has ever seen. Some 70 years and 20,000 oil wells later, the...
Large Monte Carlo Simulation of Duffing Equation
This effort aims to obtain some accurate statistics of the Duffing Equation subjected to white noise through Monte Carlo simulation. The results obtained can be used to check the accuracy...
A New Approximate Solution Technique for Random Vibration of Hysteretic Systems
Approximate probability densities are obtained for the response of hysteretic systems under Gaussian white-noise excitations. The method of analysis is applicable to either bilinear or...
Tales From Milwaukee's Underground
Written from RETC papers and interviews, this article is a status update on the Milwaukee Metropolitan Sewerage District's $2.1 billion Water Pollution Abatement program,...
A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...
Next Stop: The Los Angeles Metro Rail
The Los Angeles Metro Rail is a $6.5 billion light and heavy rail system, which may be entirely completed by the year 2000. A 22 mi segment of the 150 mi light rail system, connecting...
Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
Volatilization of Cesium and Ruthenium From High-Level Waste Glass
The contamination of the air above high-level waste glass by 134Cs, 137Cs and 106Ru...
Estimate of the Source Term for a Repository Surface Facility From the Routine Processing of Spent Fuel
The potential for release of radioactive material from the proposed handling and processing of spent nuclear fuel in a surface facility for a geologic repository was evaluated. The potential...
Global Problems: Implementing Mission to Planet Earth
Serious global environmental problems are facing our generation on Earth. The decrease in ozone concentrations and the greenhouse effect have implications for all life forms on the planet....
Space-Based Control of the Climate
The expected global greenhouse warming of 2 ?C may be reversed by a space-based screen that intercepts 3% of the incident solar radiation. Space-based devices may also mitigate the ozone/UV...
Mission to Planet Earth: The Quest to Save the Environment
The Mission to Planet Earth is a program designed to look at the earth as an integrated system. It is an internationally supported project. It was conceived because the current methods...
Challenges and Opportunities in the '90s and Beyond?A U.S. Army Corps of Engineer's Perspective
In the foreseeable future, water resources expenditures will probably be dominated by environmental/water quality concerns. Strong focus is coming to bear on the state of repair, rehabilitation...
