Empirical model of Skeletonema costatum photosynthetic rate, with applications in the San Francisco Bay estuary
An empirical model of Skeletonema costatum photosynthetic rate is developed and fit to measurements of photosynthesis selected from the literature. Because the model acknowledges existence of: 1) a light-temperature interaction (by allowing optimum irradiance to vary with temperature), 2) light inhibition, 3) temperature inhibition, and 4) a salinity effect, it accurately estimates photosynthetic

Selected ground-water data, Bonneville Salt Flats and Pilot Valley, western Utah
This report contains ground-water data collected at wells and springs on the Bonneville Salt Flats and in Pilot Valley, western Utah. Most of the data were collected during a study of the hydrology and surface morphology of these two salt-crust areas during the period July 1975 - June 1977. The study was carried out in cooperation with the U.S. Bureau of Land Management. This report is intended to

Ground-water levels and quality data for Georgia, 1977
This report begins a publication format that will present annually both water-level and water-quality data. In this format the information is presented in two-page units: the left page includes text which summarizes the information for an area or subject and the right page consists of one or more illustrations. Daily mean water-level fluctuations and trends are shown in hydrographs for the previou

Numerical simulation of steady state three-dimensional groundwater flow near lakes
Numerical simulation of three-dimensional groundwater flow near lakes shows that the continuity of the boundary encompassing the local groundwater flow system associated with a lake is the key to understanding the interaction of a lake with the groundwater system. The continuity of the boundary can be determined by the presence of a stagnation zone coinciding with the side of the lake nearest the

Developing a state water plan: Ground-water conditions in Utah, spring of 1978
This report is the fifteenth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, prepared cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions.This report, like the others (see References, p. 13), contains information on wel

Geology and groundwater resources of northern Berks County, Pennsylvania
The area of investigation comprises approximately 540 square miles and lies entirely within the Great Valley section of the Valley and Ridge physiographic province. The Great Valley is underlain chiefly by carbon ate rocks in the south and by shale and graywacke in the north. Most of the carbonate rocks are included in two great nappes that differ appreciably in stratigraphic detail.

Hydrologic reconnaissance of the Fish Springs Flat area, Tooele, Juab, and Millard Counties, Utah
The Fish Springs Flat area includes about 590 square miles (1,530 square kilometers) in western Utah. Total annual precipitation on the area averages about 7 inches (180 millimeters) and totals about 232,000 acre-feet (286 cubic hectometers). Fish Springs Wash is the major drainage in the area; and, along with numerous smaller washes, it flows only in direct response to precipitation. Runoff from

Water resources of the northern Uinta Basin area, Utah and Colorado, with special emphasis on ground water supply
The northern Uinta Basin area covers about 5,200 square miles (13,470 square kilometers) in northeastern Utah and northwestern Colorado. Much of the lowlands are arid to semiarid, but the highest parts of the Uinta Mountains have a humid climate. During 1941-70, the average annual precipitation ranged from less than 8 inches (203 millimeters) in the lowest part of the area at the Green River to mo

Ground-water resources of the Parowan-Cedar City drainage basin, Iron County, Utah
The Parowan-Cedar City drainage basin, Iron County, Utah, includes about 1,100 mi2 (square miles)(2,800 km2 [square kilometers])--520 mi2 (1,300 km2) in the Parowan basin and 580 mi2 (1,500 km2) in the Cedar City basin. Parowan and Cedar City Valleys are structural depressions formed by northeast-trending faults. Parowan Valley is essentially a closed basin, whereas Cedar City Valley is drained by
