Using Water Budgets and Isotope Analysis to Explore Water Availability in Low Flow Conditions: Hartley Pond Case Study
… seasonal changes to the volume and timing of water flowing through a reservoir provides valuable information for responsible resource management. Hartley Pond is a reservoir in Duluth, Minnesota, that is formed by a dam on Tischer Creek. Solar forcing to the reservoir elevates the summer water …

Water and Energy Budgets of Snow-Covered Montane Forests: Observations, Remote Sensing, and Modeling
Montane forests provide essential freshwater resources to the local ecosystems and downstream communities worldwide. Climate change is altering the energy and water budgets of montane forests; however, the magnitude and consequences to water resources is uncertain. This dissertation seeks to …

A Conceptual Model OF Groundwater Flow in Spring Valley, NV, AND Snake Valley, NV-UT
… the Clark, Lincoln and White Pine Counties Groundwater Development Project proposed by the South Nevada Water Authority (SNWA). Water budget estimates suggest that interbasin flow accounts for a significant portion (~25%) of the water budgets in Spring and Snake Valleys. Although interbasin flow …

Economic Analysis of Infrastructure Investment and Irrigation Budget Issues in a Southwestern U.S. Water Utility
… investigate two policy issues faced by water utilities: infrastructure investment and water budget programs. Water utilities have infrastructure that is deteriorating at an increasing rate, necessitating higher rates of investment from ratepayers. At the same time utilities must improve …

Evolution of oceanic margins : rifting in the Gulf of California and sediment diapirism and mantle hydration during subduction
… that the upper mantle is hydrated by seawater flowing along outer-rise normal faults. These measurements indicate that the upper mantle is ~1.57 to 6.89% anisotropic, and this anisotropy can be attributed to bending-related faulting and an inherited mantle fabric. Accounting for …

Modeling the impact of iIrrigation on precipitation over the Great Plains.
… has been shown to modify the surface energy and water budgets over the Great Plains by altering the partitioning of latent and sensible heating. An increase in latent heating from irrigation contributes to a cooler and more humid surface, which has competing impacts on convection. In this study, …

Modelling hydrologic system change in a paraglacial catchment in the Northern Rocky Mountains
… but a complete examination of changes in the water budget. Alpine catchments are increasingly vulnerable to evapotranspirative losses due to climatic warming, and the rates of vegetation succession are often unable to keep up with the rate of warming. Basin scale analyses of glacial recession …

Evaluation of a Water Budget Model for Use in Wetland Design
… As a result, correctly estimating the wetland water budget, is essential to the success of created wetlands. A wetland water budget model, Wetbud, was developed by collaborators from Virginia Tech, Old Dominion University, and the Technical University of Crete for estimating wetland water …

Investigating the Water Budget and Subsurface Hydrology of Two Rain Gardens in Calgary, Alberta
… impervious surfaces that prevent stormwater from infiltrating into the soil. Rain gardens are a form of low impact development technology that mitigate some of these effects by promoting natural stormwater infiltration. Rain gardens have extensively been researched in warm and humid …

Groundwater and Tidal Controls on Wetland Hydrology, Julie J. Metz Wetland Mitigation Bank, Woodbridge, Virginia
… Metz Wetlands Mitigation Bank, a 92-hectare freshwater wetland located in Woodbridge, Virginia, borders the tidally-influenced Neabsco Creek. Seven pods separated by earthen berms were built by Wetland Studies and Solutions Inc. (WSSI) in 1995 and 1997 by removing the toe of small sandy alluvial …

Physiological and behavioural responses to temperature and humidity in fossorial amphibians
… on the thermal sensitivity of metabolism and water loss in Ambystoma maculatum. My findings suggested that acute changes in temperature affected energy and water budgets. However, acclimatory changes in temperature affected metabolism but not water loss. I then examined how temperature (17°C …

Modeling land surface processes of the midwestern United States : predicting soil moisture under a warmer climate
… and RegCM3-BATS1e to simulate the energy and water budgets of the American Midwest. Several errors in both RegCM3 and IBIS were identified and corrected, including a significant warm bias, an underestimation of root zone soil moisture, and an overestimation of incident surface shortwave …

Characterization of the spatial and temporal variability in pan-Arctic, terrestrial hydrology
… system, and there are signs that significant water-cycle changes, involving complex feedbacks, have occurred. This dissertation explores the methods to estimate components of the arctic hydrological cycle, the numerous biases and uncertainties associated with the techniques, and suggestions …

Anthropogenic impacts on recharge processes and water quality in basin aquifers of the desert Southwest : a coupled field observation and modeling study
… mechanisms and raised questions about groundwater sustainability. Past efforts focused on recharge in arid basin systems used three main assumptions: there is minimal modern recharge, no widespread recharge on basin floors, and no recharge from anthropogenic sources. However, in the …
