U.S. Geological Survey reports on the water resources of Florida, 1886-1980
Nevin Douglas Hoy, James D. Simmons, Maude Claiborne
1981, Open-File Report 81-816
The U.S. Geological Survey has been making investigations of the water resources of Florida since the latter part of the 19th century. The earlier work consisted mainly of data collection at a few spring and river sites at intermittent intervals with the exception of a statewide ground-water study made during...
Assessment of the Santa Margarita Sandstone as a source of drinking water for the Scotts Valley area, Santa Cruz County, California
K. S. Muir
1981, Water-Resources Investigations Report 81-6
Scotts Valley, Calif., is a rural residential area with a rapidly expanding population. Its mediterranean-type climate yields an average annual rainfall of 40 inches. The Santa Margarita Sandstone is the principal aquifer in the area, supplying about 90 percent of all water for domestic purposes. Sources of recharge for the...
Digital models of ground-water flow in the Cape Cod aquifer system, Massachusetts
John H. Guswa, Denis R. LeBlanc
1981, Open-File Report 80-67
The Cape Cod aquifer system was simulated with three-dimensional finite-difference ground-water-flow models. Five areas were modeled to provide tools that can be used to evaluate the hydrologic impacts of regional water development and waste disposal.The model boundaries were selected to represent the natural hydrologic boundaries of the aquifer. The boundary...
Map showing vegetation distribution in the central part of the East Tintic Mountains, Utah
Nancy Milton, Daryl P. Madura
1981, Miscellaneous Field Studies Map 1195
With the development of remote sensing technology has come the capability of defining and mapping plant communities by means of their spectral properties.  Such maps will be an important aid in resource evaluation and management, especially in densely vegetated and remote areas of the world. This study in part of a...
