Time-Dependent Landslide Probability Mapping
Case studies where time of failure is known for rainfall-triggered debris flows can be used to estimate the parameters of a hazard model in which the probability of failure is a function...
A Geotechnically-Oriented GIS for Seismic Hazard Mapping
A geotechnical GIS has been configured by the California Department of Conservation's Division of Mines and Geology for the purpose of designating seismic hazard zones as mandated by recent...
Digital Evaluation of Contaminated Sites
This paper introduces digital techniques to evaluate historical maps and aerial photographs in order to detect contaminations on derelict industrial sites. Special attention is paid to...
Skills for Local Government
One job every engineer must do is craft their philosophy of engineering. That is, they must bring together the rules they will use to guide and shape their engineering form. This philosophy...
GIS: New York's Pipe Dream
To be of any use to managers, infrastructure data must be compiled in a form they can use. The answer for the 1990s is a geographic information system that electronically combines data...
High-Resolution Interwell Seismic Experiments in Sedimentary Formations
High-frequency interwell seismic data were acquired to examine full waveforms recorded in the pulsed mode and in the swept mode as well as to perform traveltime inversion tomography for...
Irrigation and Drainage System As-Built Map Preparation Using Satellite Digital Imagery and a GIS
Multispectral remote sensing from satellite platforms has led to the development of numerous applications which use digital imagery for the classification and mapping of natural resources...
Crop Classification and Area Estimation Using Airborne Multispectral Video/Radiometer Remote Sensing
The U.S. Agricultural Stabilization and Conservation Service (ASCS) in Logan, Utah, combines color slide 35 mm aerial photography with color video imagery to perform routine (yearly) crop...
Engineering Answers to Groundwater Impact Questions Using a Geographic Information System (GIS)
Environmental concerns have raised complex questions about the impacts of increased groundwater levels adjacent to navigational pools along the Red River, Louisiana. Previous studies had...
CAD and the Corps
CAD has been a near standard feature of engineering design for the last decade, but the U.S. Army Corps of Engineers has found that the way their installations have gone about designing...
Signing Systems: Directional, Identity, and Graphic Systems for the Port of Long Beach
The authors have developed (in conjunction with Port staff) a revolutionary roadside communication system for The Port of Long Beach. The system includes: Renamed piers for easier understanding...
Modeling Variable Width Buffer Zones with a Geographic Information System
It is possible to gain significant protection of water resources from nonpoint pollution with buffer strips, but frequently a single width strip is not appropriate. Geographic information...
The Physiography and Engineering Constraints of the Continental Slope in the Northwestern Gulf of Mexico
The emplacement of structures on the seafloor has always been difficult but until recently, few knew just how difficult possible construction on the Northwestern Gulf of Mexico Continental...
Small Utility GIS
Geographic information systems are revolutionizing much of the civil engineering field, providing engineers and managers with a new tool to relate databases and maps. But despite the benefits...
Laboratory Observations of Macroscopic Failure Modes in Freshwater Ice
A review is presented of tests performed in the laboratory by several investigators on indentation in freshwater ice. A number of the observed failure modes are discussed. From the results,...
Major Results of Gravity and Magnetic Studies at Yucca Mountain, Nevada
About 4,000 gravity stations have been obtained at Yucca Mountain and vicinity since the beginning of radioactive-waste studies there in 1978. These data have been integrated with data...
A Regional Mapping Procedure for Finite Element Mesh Design
The paper summarizes our recent work in the development of practical algorithms for the automated mesh design in finite element stress analysis. A regional mixed mesh improvement procedure...
Building a Geographic Information System (GIS) for Siting New York City Sludge Management Facilities
Siting studies for waste facilities usually focus on a particular geographic region, or a defined study area, and are restricted to a specific technology. However, the siting of land-based...
Application of GIS to the Planning and Preliminary Design of the Vancouver Island Highway
Crippen Consultants and Reid, Collins and Associates(divisions of H.A. Simons Ltd) have completed the corridor selection and preliminary design of a section of the Inland Island Highway...
GIS in Transportation Modeling: Merging MINUTP with GIS
Transportation system modeling involves a great deal of information on features which are geographically distributed over a study area. Geographic Information Systems (GIS) are suited...
