The Precast Pier
For the U.S. Navy's Strategic program, a 1,410 ft long pier was constructed on New York City's Staten Island. The combined efforts of three engineering firms,...
Making Use of Contaminated Soils
Using hot-mix asphalt (HMA) is one answer to contaminated soil. HMA plants can be modified to accept some contaminated soil�a boon not only to the generator of the soil but the asphalt...
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...
What Will Happen to Local Rural Roads and Bridges
Much of the local rural road and bridge system was not designed for the heavy trucks and farm equipment that are currently using the system. The system will continue to deteriorate unless...
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...
