Laboratory manual: mineral X-ray diffraction data retrieval/plot computer program
Phoebe L. Hauff, George Van Trump
1976, Open-File Report 76-407
The Mineral X-Ray Diffraction Data Retrieval/Plot Computer Program--XRDPLT (VanTrump and Hauff, 1976a) is used to retrieve and plot mineral X-ray diffraction data. The program operates on a file of mineral powder diffraction data (VanTrump and Hauff, 1976b) which contains two-theta or 'd' values, and intensities, chemical formula, mineral name, identification...
Ground-water levels in observation wells in Oklahoma, 1971-74
Robert L. Goemaat
1976, Open-File Report 76-664
The objectives of the observation-well program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate the future availability of ground-water supplies, and (3) to provide information for use in basic research. These selected records serve as a...
Dissolved solids, hardness, and orthophosphate of surface-water runoff in the Northwest Florida Water Management District
J.E. Earle
1976, Water-Resources Investigations Report 76-16
This atlas consists of three maps that show the general distribution of dissolved solids, hardness, and orthophosphate in the streams and lakes within the Northwest Florida Water Management District. The atlas was prepared in cooperation with the Water Management District to provide pertinent water-quality information relating to the objectives of...
The karst landforms of Puerto Rico
Watson H. Monroe
1976, Professional Paper 899
Puerto Rico has a great variety of landforms developed by solution of limestone under tropical climatic conditions. Karst topography is present in most parts of Puerto Rico where limestone crops out, but it is more highly developed in the northern and northwestern parts, which are underlain by thick limestone formations of Oligocene and Miocene age....
Numerical simulation analysis of the interaction of lakes and ground water
Thomas C. Winter
1976, Professional Paper 1001
Because the interrelationship of lakes and ground water is perhaps the least understood aspect of lake hydrology, vertical-section, steadystate, numerical-model simulations were run to evaluate the factors that control the interaction of lakes and ground water. The study is concerned only with lakes encircled by water-table mounds that are at...
