Living with the Shore: Hazard Mitigation through Education
In 1977, the authors began the task of producing summary texts for all mainland open-ocean coastal states as well as Chesapeake Bay, Puget Sound, and Lakes Erie and Michigan. On completion,...
Accuracy of Computed Water Surface Profiles
Stream cross-sectional geometry obtained from aerial surveys (aerial spot elevations and topographic maps) that conform to mapping industry standards are more accurate than is often recognized....
Managing Water Resources Using Geographic Information Systems as a Tool
The Oregon Water Resources Department is designing and using a geographic information system (GIS) to manage water rights. The system allows automation of many tasks including: production...
The Applicability of Satellite Altimetry Data to Tidal Models
Different tidal regimes require different data assimilation schemes. In all cases, however, it is better to perform a separate tidal solution before assimilation. For proper assimilation...
Mapping of Drought Status in South Florida
The Water Management District (the District) sets regulations to guide water users in conservation of water use in four phases of drought severity. The District's Governing Board is responsible...
Application of Satellite Remote Sensing for Identification of Irrigated Lands in the Newlands Project (
As one element of Operating Criteria and Procedures for the Newlands Project in west-central Nevada, the Bureau of Reclamation has compiled an irrigation water rights spatial data base....
CAD Maps Ocean Floor
This article describes the Navy's use of computer aided design to map-out a 250 sq mi expansion of an anti-submarine warfare training facility in St. Croix, Virgin Islands. Three hundred...
Preliminary Seismic Risk Maps for Puget Sound
Ground shaking during Puget Sound earthquakes is characterized by irregularly shaped areas of high intensity ground motion, not all of which are correlated with soil type. Simulation of...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
CAD Mapping Trailblazer
Until three years ago, few civil/surveying firms had automated both surveying (including digital recording of angles and distances shot in the field) and the related design and drafting....
From Micro to Supermicro
The Association of Central Oklahoma Governments found that simply replacing its microcomputers with supermicros wasn't enough to tackle large files of census tracts and other mapping data....
Engineering Methodology for Delineating Debris Flow Hazards in Los Angeles County
Utilizing historical and field data, elementary geomorphology and simplified hydraulics of debris flows, a mapping strategy has been developed. The delineation procedure includes defining...
Remote Sensing to Assess Effects of Hydroelectric Development
Planning for hydroelectric development of rivers in the province of Ontario, Canada requires extensive environmental evaluation and assessment. To test the feasibility of using digital...
A GIS to Predict Non-Point Source Pollution Potential
The non-point pollution potential of agricultural lands was analyzed using a geographic, computer based system. Bacterial pollution received special emphasis. The system accepts digitally...
Analysis of Alluvial Fan Flooding
Alluvial fans are estimated to cover approximately one third of the land area in the southwestern United States. Because of their relatively gentle slopes and well draining characteristics,...
Microcomputer Implementation of Geographic Information Systems
