Evaluating Groundwater Pollution Potential Using Geographical Information Systems
A procedure for developing groundwater pollution potential maps using a geographical information system (GIS) is introduced. The concept of pollution potential mapping is discussed, along...

Mapping Ground-Water Sodium Adsorption Ratios in Northern Louisiana
High sodium concentration is suspected as the cause of several crop failures in the northern part of Louisiana. This study, using Geographic Information Systems (GIS) technology, was undertaken...

Improvements to Mapping of Alluvial Fan Flooding
The Federal Emergency Management Agency (FEMA), which is responsible for identifying floodplains for the National Flood Insurance Program, is working to refine its assistance to engineers...

Multi-Date Image Analyses Used for Determining Flood Area Impacts in the Saginaw River Basin, Michigan
During the months of September and October 1986, a series of storms swept across the Lower Peninsula of Michigan. These heavy downpours caused $400 million worth of flood damages. Significant...

Application of Geological Information to Arizona Flood Hazard Assessment
Hydrological modeling procedures applied to regulatory flood-hazard zonation can be misapplied when assumptions concerning flood-hazardous processes are violated. Geomorphological mapping...

Land Use Change and Soil Erosion Hazard in the Zambezi Basin
An experimental model for estimating soil erosion hazard in southern Africa (SLEMSA) was linked to a raster based Geographical Information System. Soil erosion hazard maps were constructed...

U.S. Geological Survey DLG-3 and Bureau of the Census TIGER Data: Development and GIS Applications
The U.S. Geological Survey has been actively developing digital cartographic and geographic data and standards since the early 1970's. One product is Digital Line Graph data, which offer...

A Robotic Return to the Moon
An autonomous Lunar precursor mission is proposed as the first step to an effective, low cost return of man to the Lunar surface. The mission would use two self similar robotic vehicles...

Statistical Analysis of Australian Ground Snow Loads
This paper is concerned with the statistical analysis of snow data from the alpine areas of southeastern Australia (above 1200 m). In these areas, the local variation is large and contour...
