Minipiles Mature in America
After being born more than 40 years ago in Europe, minipiles are maturing in the United States. Their distinctive feature is a relatively small diameter, rarely larger than 12 in. Constructing...
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...
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...
Load and Resistance Factor Design for Engineered Wood Construction
A Pre-Standard Report
The information contained in this pre-standard report is intended to provide guidance to writers of a load and resistance factor design (LRFD) specification for engineered wood construction....
Basis for Design of Wet Detention Basin BMP's
Two different approaches have typically been used to formulate design criteria for wet detention basin best management practices (BMP's). One approach relies upon solids settling...
Monitoring and Design of Stormwater Control Basins
The City of Austin, Texas, has played a pioneering role in the control of urban nonpoint source pollution by enacting watershed and stormwater ordinances, overseeing detailed monitoring...
Swedish Approach to Infiltration and Percolation Design
Design of infiltration and percolation facilities is similar to detention facilities. The storage volume of an infiltration basin being the ponding volume on top of the infiltration surface...
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,...
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...
Concrete Pavement Rehabilitation Research Findings
A study to improve the procedures for evaluating and rehabilitating concrete pavements was undertaken in 1985. Field and analytical studies have facilitated a new knowledge and understanding...
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...
Hydraulic Effect of Turbid Water Infiltration Through a Shallow Basin
A 225 m2 test basin was operated from September 1986 through October, 1987, to determine the hydraulic effects of turbid water application. Initial...
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 to the Floridan Aquifer System, Orlando Area, Central Florida
Approximately 400 drainage wells exist in Orange County, central Florida. The rate of recharge through drainage wells is limited by the rate of surface flow to the wells; the hydraulic...
Artificial Recharge of the Heretaunga Plains Aquifer Hawke's Bay, New Zealand
The Heretaunga Plains groundwater system in the Hawke's Bay region of New Zealand, is naturally recharged from the nearby Ngaruroro River at the approximate rate of 5.5m3/sec....
Artificial Recharge of Ground Water
A need for international and interdisciplinary technology transfer on the subject of artificial recharge resulted in the American Society of Civil Engineers' (ASCE) Irrigation...
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...
Analyses of Foundation Failures
During the earthquake of September 19th, 1985, many buildings tilted and underwent settlements, sometimes of very large magnitudes. This paper describes and analyzes these settlements....
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...
