From Soft Soils to Heavy Construction
A new construction technique using geotextiles and upward flowing water is bringing heavy construction to soft shores. Two projects�a truck yard in Seagirt, Md., and a containment dike...
Seismic Cutoff
The John Hart Dam, which is a 40-year old dam in British Vancouver, Canada, has been rehabilitated to meet current seismic codes. BC Hydro, the utility that owns the dam, conducted a study...
New Horizons in Construction Materials
While civil engineers have, for centuries, built structures and other physical facilities using whatever materials are available to them, there is always the need for stronger, more durable,...
Source Control of Oil and Grease in an Urban Area
We explored a variety of techniques to remove oil and grease from urban stormwater runoff. Previous work has shown that relatively high concentrations and substantial mass loadings of...
Source Tracing of Toxicants in Storm Drains
Sources of toxic chemicals in storm drains are often difficult to locate and even more difficult to control. Receiving environment chemistry, storm drainage maps, land use information,...
Safety Performance Evaluation of 21st Century Appurtenances
A great deal has occurred in the highway safety field in the last 15 years: there have been societal changes which have altered the character of the vehicle fleet; there have been technological...
Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...
Systems for Artificial Recharge of Ground Water
Design and management of infiltration systems should be adapted to local conditions of water quality, climate, soil, hydrogeology, and environmental constraints. Aspects to be considered...
Artificial Recharge Research at the University of Arizona
This paper summarizes pit- and well-recharge trials at Tucson, Arizona. The pit recharge trials examined management techniques and characterized flow patterns in the 80 ft thick vadose...
Artificial Recharge of Urban Storm-Water Runoff
The disposition of selected contaminants in the soils, in the percolating water, and in the recharge-mound water of five retention/recharge basins was investigated in Fresno, California....
Ground Water Recharge Through Excavated Basins
Excavated basins were used to bypass slowly permeable soils in the Southern High Plains and artificially recharge the Ogallala aquifer. Recharge rates with turbid playa water were as rapid...
Infiltration Maintenance in Recharge Facilities of Orange County Water District
The Orange County Water District manages the Orange County ground water basin in western Orange County. In the first 25 years of operation, the District made exclusive use of the Santa...
Status and Experiences Made in the Artificial Recharge of Ground Water in the Federal Republic of Germany
With a rate of 72%, ground and spring water is the most important raw material for drinking water supply in the Federal Republic of Germany. Ground water, however, is not available everywhere...
Journal of Aerospace Engineering
The Journal of Aerospace Engineering promotes the implementation and development of space and aerospace technologies and their transfer to other civil engineering applications. Topics of interest include...
Breakwater Breakthrough�Bold New Breakwaters
A new rubble-mound breakwater design is a departure from the conventional approach detailed in the U.S. Army Corps of Engineers Shore Protection Manual. The new concept, called the berm...
Should Fast Track be Derailed?
Engineers, architects and owners believe that fast track construction is a great idea when it works, but serious problems can arise. Some engineers feel that the owner reaps all the benefits...
Overview of Factors Involved in the Mexico Earthquakes
The Mexico earthquakes provided many opportunities for learning. New knowledge has been obtained and continuing research will provide additional knowledge. The earthquakes have also demonstrated...
Damage Statistics of the September 19, 1985 Earthquake
Grupo ICA has participated in all stages of the actions and analysis of the effects of this quake aimed at taking advantage of this disastrous experience and has prepared a complete study...
Geotechnical Notes on the Effects of Mexico's 1985 Earthquakes
The present notes briefly describe the most relevant effects of the September 19 and 20, 1985 earthquakes on shallow and deep foundations used in Mexico City, which is located at about...
Effects of the 1985 Earthquake in Lazaro Cardenas, Mich.
An account is presented of a geotechnical survey made shortly after the major earthquake of September 19, 1985 (magnitude 8. 1) at the industrial port of Lazaro Cardenas in the state of...
