A GIS Foundation Example
A primary network of geodetic control monuments was developed with static GPS measurements. These monuments are tied to the existing Florida High Precision Network....

Wanapum Dam Embankment Settlement Study
This paper discusses the long term vertical movements of a zoned earth embankment. Vertical movement of the Wanapum Dam embankment has been monitored since its completion in 1964. The...

Blast Densification of a Thick, Loose Debris Flow at Mt. St. Helen's., Washington
Numerous debris flows occurred during the 1980 eruption of Mt. St. Helen's in Washington State. The proposed location of Bridge 12 over Coldwater Creek along State Route 504 is underlain...

Low-Cost Bridge Scour Measurements
This paper reports on the use of a low-cost, highly portable sonar system. The ease of use of the instrument and the short time required to make measurements should make this system valuable...

Comparison of Current Meters Used for Stream Gaging
The U.S. Geological Survey (USGS) is field and laboratory testing the performance of several current meters used throughout the world for stream gaging. Meters tested include horizontal-axis...

Expansion and Contraction of Powder River Between Moorhead and Broadus, MT: Geomorphic Observations and Numerical Modeling
Sixteen years of annual surveys demonstrate that the channel of Powder River expands at high flows and contracts at low flows. Channel contraction is associated with the formation of benches...

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...

A Survey of Building Performance in Hurricane Iniki and Typhoon Omar

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...

Shoals System Capabilities for Hydrographic Surveying

Site Investigation Surveys for Dredging Projects

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...

Summary of Questions/Answers and Panel Discussions on Session VI: Guidelines for Instrumentation and Monitoring

GIS Mapping of Earthquake Ground Shaking in San Francisco, California
Severe earthquakes of the last decade in Mexico, Armenia, and the United States have reemphasized the importance of local geologic site conditions in estimating damage and consequent losses....

Current Forensic Courses in Civil Engineering
The ASCE is taking a leadership role in the prevention of failures of engineered facilities. The Technical Council on Forensic Engineering Education Committee recently completed a survey...

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...
