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...
AASHTO Design Concepts
The AASHO Road Test of 1958-60 grew out of a need to quantify the effects of increasingly heavier axle and gross loads and varying wheel load configurations on the performance of this...
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...
Subsurface Injection of Storm Water Runoff into an Underground Storage of Bangkok
Subsurface injection through a well into sand and gravel formations of the Bangkok aquifer of untreated canal water whose composition considered similar to that of storm water runoff,...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
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...
Artificial Recharge of Ground Water via Paddy Fields in an Alluvial Fan, Northern Japan
Artificial ground water recharge via paddy fields was tested during the winters of 1985/86 and 1986/87 in order to protect declining water levels. The purpose of this paper is to discuss...
Techniques of Artificial Recharge from an Ephemeral Wadi Channel Under Extreme Arid Conditions
A series of field experiments and theoretical analysis was carried out for the alluvial system in Wadi Tabalah in order to determine the feasibility of implementing artificial recharge...
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...
Earthquake Response of La Villita Dam
Due to the recent industrial and housing developments at the port of Lazaro Cardenas, located 13 km (8 miles) downstream of La Villita Dam, at the mouth of the Balsas River, the hazard...
Are the Soil Depositions in Mexico City Unique?
The answer clearly is: YES| However, the amplification and soil-structure interaction effects observed in Mexico City are important considerations - even if they may not be so severe -in...
Soil-Structure Interaction in Mexico City During the 1985 Earthquakes
The effects of the flexibility of the soil and the foundation on the seismic response of structures, by opposition to clear foundation failures, cannot be easily identified from a simple...
Performance Characteristics of Structures, 1985 Mexico City Earthquake
The 1985 Mexico City earthquake caused major damage to buildings, but not other structures, in the center of Mexico City, located approximately 400 km. from the epicenter. Due to soil...
Behavior of Reinforced Concrete Framing Systems
On September 19, 1985, Mexico City was hit by what is believed to have been the most damaging earthquake in its recorded history. In this report, a ground motion recorded in the severely...
