Summary of Highway Product Evaluation Practices and HITEC Needs Survey
This report (CERF No. 94-5012) contains the results from a survey conducted by the Civil Engineering Research Foundation (CERF), the research affiliate of the American Society of Civil...

Minimizing the Probable Maximum Flood
A newly-developed probable maximum precipitation (PMP) estimate for Wisconsin and Michigan reduced precipitation depths by 20%. Should a given area's probable maximum flood...

Fundamentals and Advancements in Hydraulic Measurements and Experimentation
This proceedings, Fundamentals and Advancements in Hydraulic Measurements and Experimentation, contains papers presented at the Symposium held...

GPS Goes Real Time
This paper discusses the feasibility of Trimble Navigation's Site Surveyor System using Real-Time Kinematic (RTK) technology for conducting cadastral surveys. The use of RTK...

Glossary of the mapping sciences
The Glossary of Mapping Sciences, a joint publication of the American Congress on Surveying and Mapping (ACSM), American Society for Photogrammetry...

Estimating Network Model Parameters from Mail Survey Data
Network models are generally based on a four-step modeling process; trip generation, trip distribution, modal split, and trip assignment. Microcomputer implementations of these steps have...

Better Ways to Update Trip Matrices
Updating origin-destination (OD) trip matrices usually involves considerable survey costs, so engineers are often forced to use dated OD information, which can seriously undermine the...

Using License Plate Survey Data in Transportation Planning Applications
This paper is a presentation of the methodology used by the Baltimore Regional Council of Governments to conduct a multi-faceted study for the Maryland Aviation Administration, which operates...

Scoping the Monitoring Instrumentation to Meet Repository Design and Construction Needs
This paper discusses categories of instruments that are available and recommended for consideration to monitor the engineering performance and interactions of the geologic media, groundwater,...

Geotechnical Instrumentation for Repository Shafts
The United States Congress passed the Nuclear Waste Policy Act in 1980, which required that three distinctly different geologic media be investigated as potential candidate sites for the...

Scoping Out Scour
Bridge scour�soil erosion around piers and pilings�threatens tens of thousands of bridges across the U.S. Traditionally, engineers have mapped bridge scour by driving probes into the subbottom...

Dynamic Field Response Studies and Earthauqke Instrumentation of the Meloland Road Overcrossing
Ambient vibration data was obtained at the Meloland Road Overcrossing near El Centro in California by The California Department of Transportation (CALTRANS) as part of a 1978 Federal Highway...

Performance Monitoring of Concrete Structures with Embedded Sensors
This paper describes the use of embedded fiber optic sensors to monitor the performance of reinforced concrete structures. The fiber optic sensors are capable of measuring vibrations,...

Software Applications for Monitoring Instrumentation Data
The initial program for reducing instrumentation data, used by the Geotechnical Branch of the Louisville District Corps of Engineers, was written in 1969. This program did not allow for...

Development of High Performnance Shotcrete (Theoretical Considerations)
This paper presents some theoretical considerations for studies on high performance wet-mix shotcrete. A new laboratory shotcrete pump and rheometer are being developed to study the effects...

Using Environmental Tracers to Estimate Recharge Through an Arid Basin
Multiple tracer techniques were used to estimate recharge rates through unsaturated alluvium beneath the Greater Confinement Disposal site, a waste disposal site located in Frenchman Flat,...

Geophysical Investigations of Concealed Faults Near Yucca Mountain, Southwest Nevada
Detailed gravity and ground magnetic data collected along surveyed traverses across Midway Valley, on the eastern flank of Yucca Mountain, Nevada reveal that these methods can be used...

Photogeologic Reconnaissance of X-Tunnel at Little Skull Mountain
An underground structure known as X-tunnel was investigated for the viability as an underground deep based missile system that included the capability to maintain survivability following...

Results from the Second Performance Assessment Iteration for the Greater Confinement Disposal Facility
The Greater Confinement Disposal (GCD) facility was established by the Nevada office of the Department of Energy (DOE) in Area 5 at the Nevada Test Site for containment of waste inappropriate...

Testing Models of Flow and Transport in Unsaturated Porous Media
The design of an intermediate-scale flow and transport experiment in an unsaturated porous media is described. This experiment will be conducted a 3-m-diameter by 6-m-long caisson filled...
