This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Perennial wetlands in montane environments are often supported at least in part by groundwater input. Groundwater is especially important for wetlands in areas with a snow melt dominated precipitation regime and high summer evapotranspiration rates. Understanding of the groundwater hydrology that supports wetlands in montane environments is often complicated by steep topography, inadequate characterization of the subsurface material, and sparse data. This study examines the groundwater system supporting Grass Lake, the largest peatland in the Sierra Nevada Mountains, located south of Lake Tahoe, California. Field measurements are used to quantify important aspects of the hydrologic system supporting Grass Lake. Late-season groundwater flows into the peatland are estimated using surface water measurements and water budget. Groundwater contributions are approximately 2 to 10 times higher than surface water contributions after July, depending on the water year. Measurements of hydraulic gradients reveal areas of groundwater recharge and discharge. In general, there is more groundwater discharge along the southern portion of the peatland. Measurements of groundwater level relative to the peat surface indicate areas that may be more susceptible to drying and subsequent decomposition of peat. Indirect inversion of numerical models is used to estimate the value of important parameters governing groundwater flow in the peatland. Thermal and hydrologic parameters of the peat are estimated using piezometer scale (~1m) models of heat transport. Atmospheric heat exchange and inclusion of the thermal properties of a metal piezometer improve the fit between the model and the field data. Four sets of random parameters are used to generate synthetic data. The parameter estimation process is tested by attempting to recover the original parameters used to generate the data. Including the entropy of the temperature time series as an observation improves the recovery of the original parameter values.A watershed scale hydrogeologic model is used to evaluate the potential response of the peatland to predicted changes in climate. Watershed geology was mapped at a scale of 1:5000 and used to define hydrogeologic units in the model. Field data from 2010 and 2011 were used to calibrate the hydraulic conductivity of the various geologic units in the model. Parameter estimates from the calibration process are consistent between years for all but the most sensitive parameters. Consideration of unsaturated properties of the subsurface material is shown to improve the fit between the measured and simulated heads in the peatland. The predicted change from a snow dominated to rain dominated precipitation regime results in a significant decrease in simulated late-season pressure head and saturation over approximately half of the peatland. The decrease in saturation is most significant on the east and west ends of the peatland and around the edges.

This book was released on 2005 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: A ground-water reconnaissance study of the Bijou Creek watershed in South Lake Tahoe California was done during the summer and early fall of 2003. This study provides basic hydrologic data for a region in the Lake Tahoe Basin in which a continuing loss of lake clarity is occurring in the a nearshore zone of Lake Tahoe. Wells, springs, and a surface-water site were located and basic hydrologic data were collected. Water levels were measured and water samples were collected and analyzed for nutrients. Measurements of water temperature, specific conductance, and pH were made at all ground-water sites where possible and at one surface-water site. Organic nitrogen plus ammonia, ammonia, and biologically- available iron concentrations generally were greater in the ground water in the Bijou Creek watershed than those observed in ground water elsewhere in the Lake Tahoe Basin. Nitrate concentrations were similar in the two groups. Phosphorus and orthophosphate concentrations generally were lower in the ground water of the Bijou Creek watershed compared to ground water from elsewhere in the Lake Tahoe Basin. Specific conductance and pH of ground water were similar between the Bijou Creek watershed and the Lake Tahoe Basin, but the temperature of ground water was generally greater in the Bijou Creek watershed.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
