Fabric Related Probabilistic Model for Granular Materials
A new anisotropic noncoaxial incremental constitutive model for granular materials (Jahedi et al., 1990) was developed, in which a Fabric reconstruction factor '?+',...
Construction Loads on Floors: Results of a Survey
A survey of post-shorting construction loads on floors of multi-storey buildings is described. The estimated parameters of a probabilistic model of the peak (transient) loads are reported....
Risk Based Optimal Fatigue Testing
Optimal fatigue life testing of materials is considered. Based on minimization of the total expected costs of a mechanical component a strategy is suggested to determine the optimal stress...
Risk Based Structural Optimization
Risk based structural optimization problems for structural systems are formulated on basis of a so-called risk index. The risk index is defined as a consequence modified reliability index...
ASCE Review and Publication Process for Technical Journals
For many, the review and publication process for ASCE technical journals is not clear. Though the basic steps are outlined in the Authors' Guide, there are unwritten practices that may...
What Makes a Quality Paper?
A good paper is one that is easy for members of the intended audience to read and understand. It must contain an informative abstract. The introduction should include information on why...
Engineering of Controlled-Drainage Systems
Soil-water management by water table control (via a dual purpose subdrainage-subirrigation system) is becoming popular in humid regions of the U.S. and Canada. Controlled-drainage is an...
Tapping Shallow Groundwater with Horizontal Wells
In recent years, horizontal wells have become an economical water supply source alternative for many shallow water table areas in Florida. Horizontal wells typically utilize 15 to 20 cm...
Degradation of Ground Water by Tetrachloroethylene
Ground water from many municipal water wells in California has been degraded by tetrachloroethylene (PCE) at concentrations above the drinking water standard. Investigations conducted...
Wellfield Protection Program in Broward County, Florida
The Potable Water Wellfield Protection Program was initiated early in 1981. It examined land uses in the County, made an inventory of potential ground water pollution sources, compiled...
Oklahoma's Ground Water Protection Strategy
This report examines Oklahoma's developing ground water protection strategy in light of the national strategy. We look first at relevant federal legislation and what EPA expects of a state...
Groundwater Management in Southern Florida
A water supply plan was developed by the South Florida Water Management District (SFWMD) for Hendry County, Florida as part of the Lower West Coast Water Supply Plan. In the course of...
Ground Water Management in Arkansas
Arkansas has historically enjoyed plentiful water and has typically resolved water conflicts with case by case application of common law. As agricultural, industrial and domestic water...
Evapotranspiration Data Management in California
This paper will discuss components of the California Irrigation Management Information System (CIMIS). CIMIS is an automated agricultural weather network operated by the California Department...
Use of the TETrans Model in Predicting ET Effects on Groundwater Quality
Recently Corwin and Waggoner (1991) developed a contaminant transport software package referred to as TETrans, (acronym for Trace Element Transport). TETrans is a useful preliminary assessment...
Predicting Water Quality as Affected by ET Using the Root Zone Water Quality Model
The Root Zone Water Quality Model (RZWQM) is a physically based simulation model used to predict water and solute movement running from, moving through, and leaching out of the root zone....
Irrigation Project Modernization
Project modernization for sustainable irrigation requires a design and operation plan which will provide water deliveries with flexibility and reliability at each level within the system....
Technology Transfer Lessons from a U.S. Water District
An interceptor canal will be constructed near the end of eight laterals to collect and transport operational discharge and returned farm deliveries to a reservoir for temporary storage....
Technology Transfer for Projects in South America
Engineering services were provided for three projects in South America. One project was located in the Pampa Region of Argentina and two others in northern Brazil. The projects were: 1)...
Greenhouse Irrigation Technology Transfer in Spain
In recent years, an intensive horticultural production system using unheated, plastic greenhouses has been widely adopted in the Mediterranean basin. Greenhouses now occupy more than 15,000...
