Data Dictionary and Discussion for the Midnite Mine GIS Database

Description: Abstract: A geographic information system (GIS) database has been developed by the U.S. Bureau of Mines (USBM) for the Midnite Mine and surroundings in northeastern Washington State (Stevens County) on the Spokane Indian Reservation. The mine is an open pit uranium mine which has been inactive since 1981. The GIS database was compiled to serve as a repository and source of historical and research information on the mine site. The database supported USBM hydrological and reclamation research on … more

Edwards Aquifer Recharge Zone - Chapter 213 Rules. TSMS Version

Description: This report amends and updates the geographic areas that are regulated under the Edwards Aquifer Protection Program in Texas. Using Digital Geospatial Metadata, a GIS layer is added to reflect the changes in land boundaries and the re-designation of areas as transition zones, contributing zones, and recharge zones; the result will serve as a replacement for hard copy maps of the area.

An Analysis of Adding Land Cover as a Variable to the DRASTIC Ground Water Model

Description: This study involved a geographic information systems (GIS) approach to modeling ground water pollution potential in the Southern Edwards Aquifer Region in Texas. The DRASTIC ground water model was analyzed using two methods. First, the effects of adding land cover data to the drastic model were evaluated. In the second approach, the effects of the removal of DRASTIC variables were evaluated. Six, five, and four variable models were generated and analyzed.

The proposed Fastrill Reservoir in east Texas: A study using geographic information systems.

Description: Geographic information systems and remote sensing software were used to analyze data to determine the area and volume of the proposed Fastrill Reservoir, and to examine seven alternatives. The controversial reservoir site is in the same location as a nascent wildlife refuge. Six general land cover types impacted by the reservoir were also quantified using Landsat imagery. The study found that water consumption in Dallas is high, but if consumption rates are reduced to that of similar Texas c… more
