The new definitive map of White Oak Lake

Description: A map of White Oak Lake was drawn from points on the shoreline established with the use of an electronic distance-measuring theodolite and a hand-held reflecting prism. Average water depths were determined along six transects. A planimeter was used to estimate the area of each section. The volume of each section was determined by multiplying the surface area by the average depth. The total area and volume of White Oak Lake were estimated to be 6.88 ha (17.0 acres) and 43,893 m{sup 3}(1,546,330 ft{sup 3}), respectively. The lake's surface area has been reduced at an average rate of 0.7% per year, and its volume has been reduced at an average rate of 1.1% per year. The volume of the lake can be reliably estimated only from current depth measurements throughout the lake, not from stage heights at the dam. The lake should be remapped periodically, and an estimate of the sediment volume should be made. 6 refs., 3 figs., 1 tab.

Data base management activities for the Remedial Action Program at Oak Ridge National Laboratories (ORNL)

Description: The Oak Ridge National Laboratory (ORNL) Remedial Action Program (RAP) was established in 1985 in response to state and federal regulations requiring comprehensive control over facility discharges and cleanup of contaminated sites. A computerized Data and Information Management System (DIMS) was developed for RAP to (1) provide a centralized repository for data pertinent to RAP and (2) provide support for the investigations and assessments leading to the long-term remediation of contaminated facilities and sites. The current status of DIMS and its role in supporting RAP during 1989 are described. The DIMS consists of three components: (1) the Numeric Data Base, (2) the Bibliographic Data Base, and (3) the Records Control Data Base. This report addresses all three data bases, but focuses on the contents of the Numeric Data Base. Significant progress was made last year with the geographic information system (GIS) and ARC/INFO, which can be interfaced with SAS/GRAPH to provide combined mapping and statistical graphic products. Several thematic layers of GIS data for the Oak Ridge Reservation are now available. 18 refs., 8 figs., 19 tabs.
