Climatic Perspective on the 1993 Mississippi R. Flood
The 1993 summer flooding in the Upper Mississippi River Basin was the most devastating flood of modern times with damage estimates in the range of 15-20 billion dollars. The paper describes...

Boundary Conditions and Flow Patterns in a Mountain River
Flood flow patterns in mountain valleys may be influenced by longitudinal variations in channel and valley morphology and by temporal variations in boundary conditions. This study utilizes...

Estimation of Design Surge Heights by Utilizing Meteorologic and Oceanographic Data
Data on cyclonic storm surge height have been generated with the help of a statistical simulation model. Data on observed maximum cyclonic wind speed and the length of the continental...

Water Quality Enhancement Technology for River-Reservoir Systems
Water quality enhancement technology is applied to a wide variety of field conditions in surface waters including rivers, lakes and reservoir epiliminia, lake and reservoir hypolimnia,...

The Influence of Boundary Conditions on Beach Zonation

Verification of the Shearstress Boundary Conditions in the Undertow Problem

America's Pavements: World's Longest Bathtubs
Pavements are the most unusual structures designed by civil engineers. Water flows through their tops, bottoms and sides but because pavements are relatively flat, flows out again very...

Control of Aging Processes in Wastepaper Fiber Reinforced Cement

Assessment of Distress Models for Prediction of Pavement Service Life

Monitoring and Predicting Corrosion of Weathering Steel

Integration of a Municipal Pavement Management System with a Geographic Information System
This paper describes the use of a Pavement Management System (PMS), and the integration of the pavement condition data with a Geographic Information System (GIS). In June 1988, the Pavement...

Winter Storm Mapping a Geographic Information Systems Transportation Applications
The Winter Storm Mapping System (WSMS) has grown out of our Geographic Information System for Transportation (GIS-T). The development of this project began the spring of 1991 on the State...

The Traffic Operations Control Center Simulator
As a part of a national effort to improve the operatinal efficiency of the highway network, the California Department of Transportation (CALTRANS) is developing and implementing general...

Spreadsheet Pavement Management Systems for Local Roads
Changes in administration and funding levels at the local government level are continuing to illustrate the need for information systems to aid the county engineer or public works director....

Experimental Testing of Laterally Loaded Large Scale Bridge Abutments
The challenges to a bridge analyst in defining abutment boundary conditions and the current state of the practice are presented. Variables within the abutment system are defined and discussed...

Full-Scale Bridge Test to Monitor Vibrational Signatures
A full-scale highway bridge, in the process of being demolished and replaced was monitored using vibrational techniques in its in-service condition. The bottom flange and web of one fascia...

To the Limits of Shotcrete Linings
In the 1950s for the first time shotcrete was used because an essential support measure to guarantee the stability of an underground opening in Austria, Detzelhofer (1). Since that time...

Ambient Air Monitoring to Support HLW Repository Site Characterization
This paper is a description of the program that has been operating in support of the Yucca Mountain site site characterization activities since 1985.The ambient air monitoring is designed...

PDS: An Expert System for Distress Diagnosis of Flexible Pavements in Taiwan
Pavement distress diagnosis requires a significant amount of engineering judgement which is difficult, if not impossible, to be quantified. This is an excellent domain for the development...

Computer Aided Analysis/Design of Overlays in Cracked Road Pavements
In this contribution CAPA, a user-friendly, PC based, finite element system, capable of analyzing and dimensioning pavement overlays is presented. Because of the generality of the finite...
