Spatiotemporal Heterogeneity Of Water Flowpaths Controls Dissolved Organic Carbon Sourcing In A Snow-Dominated, Headwater Catchment, Anna G. Radke, Sarah E. Godsey, Kathleen A. Lohse, Emma P. Mccorkle, Julia Perdrial, Mark S. Seyfried, W. Steven Holbrook

College of Arts and Sciences Faculty Publications

The non-uniform distribution of water in snowdrift-driven systems can lead to spatial heterogeneity in vegetative communities and soil development, as snowdrifts may locally increase weathering. The focus of this study is to understand the coupled hydrological and biogeochemical dynamics in a heterogeneous, snowdrift-dominated headwater catchment (Reynolds Mountain East, Reynolds Creek Critical Zone Observatory, Idaho, USA). We determine the sources and fluxes of stream water and dissolved organic carbon (DOC) at this site, deducing likely flowpaths from hydrometric and hydrochemical signals of soil water, saprolite water, and groundwater measured through the snowmelt period and summer recession. We then interpret flowpaths using …

1998 - Salinas Valley Water (Preliminary Analysis Of) The Cause And Cost Of Seawater Intrusion

Miscellaneous Monterey and San Luis Obispo County Documents and Reports

An analysis of the historical cause of seawater intrusion in the Pressure Area of Monterey County. An annual overdraft of groundwater resources near the coast coupled with a seasonal cycle of over pumping created a reversal in the groundwater gradient and associated cones of depression. "Marine intrusion has occurred in the 180-foot aquifer in recent years as a result of overdrafts." (Bulletin 52, 1946, p.27). The only overdrafts on groundwater in the Salinas Valley were in the East Side and Pressure Areas. "There was no shortage of groundwater in the remainder of the basin and no threat of deficiency under …

Area has become intruded by seawater, especially between cities of Castroville and Salinas.

Sustainably Managing Groundwater - Surface Water Interactions Within The Santa Rosa Plain Basin, Rhianna Frank

Master's Projects and Capstones

In this paper, I designed a strategy for implementation of sustainably managing groundwater-surface water interactions in the Santa Rosa Plain Basin in compliance with the requirements set forth by the Sustainable Groundwater Management Act of 2014. The research objectives for this analysis are: (1) to fully examine the requirements of the Sustainable Groundwater Management Act and the implications that implementation will have on the Santa Rosa Plain Basin, (2) to use technical data gathered regionally coupled with related policy design theory to analyze how groundwater and surface water interactions can be managed to meet the requirements set forth in this …

Ncer Assistance Agreement Annual Progress Report For Grant #83582401 - Assessment Of Stormwater Harvesting Via Manage Aquifer Recharge (Mar) To Develop New Water Supplies In The Arid West: The Salt Lake Valley Example, Ryan Dupont, Joan E. Mclean, Richard C. Peralta, Sarah E. Null, Douglas B. Jackson-Smith

Civil and Environmental Engineering Faculty Publications

The goals of the original proposed project remain the same, that is, to test the hypothesis that Managed Aquifer Recharge (MAR) for stormwater harvesting is a technically feasible, socially and environmentally acceptable, economically viable, and legally feasible option for developing new water supplies for arid Western urban ecosystems experiencing increasing population, and climate change pressures on existing water resources. The project is being carried out via three distinct but integrated components that include: 1) Monitoring of existing distributed MAR harvesting schemes involving a growing number of demonstration Green Infrastructure (GI) test sites; 2) Integrated stormwater/vadose zone/groundwater/ ecosystem services modeling; and …

Lithologic Constraints On The Hydrological Parameters Of Regional Aquifers In The Ibb Province, West-Central Region Of Yemen (Middle East), Malek Shami, Zarine Ali, Wedad Abdurabu, Nazrul I. Khandaker, Stanley Schleifer

Publications and Research

The lithology of the Ibb Province Yemen (Middle East) consists of Precambrian gneissic bedrocks with post-tectonic intrusions of granite and granodiorite. The overall topography is dominated by extensive volcanic extrusions that randomly surround Ibb Province with minimal Mesozoic sedimentary outcrops. According to the Yemen Geological Survey and Mineral Resource Board (YGSMRB), the origin and age of such extrusive bodies that manifest on the surface as dikes, lava flows, and small (currently passive) cinder-cone volcanoes are of Cenozoic age associated with the rifting episode of the Arabian Peninsula and subsequent opening of the Red Sea. The overall aerial extension of the …

Assessment Of Groundwater Quality In The Al Khatim And Remah Area Of The United Arab Emirates, Qasim Raza Khan

Civil and Environmental Theses

Groundwater constitutes an important part of the available water resources in arid areas. Knowledge of the quantitative and qualitative status of groundwater is a key aspect in optimal groundwater management. The chemical characteristics of groundwater in two neighboring areas (Remah and Al Khatim) have been used to identify the processes controlling groundwater chemistry in the sand aquifer of Abu Dhabi Emirate, United Arab Emirates. Furthermore, the suitability of the groundwater for agricultural purposes was assessed using a range of indices. Both areas showed elevated levels of nitrate, potassium and cadmium, indicating the impact of agricultural activities. The groundwater was found …

This report describes the hydrological hazards assessment for the Irwin focus area.

The Irwin focus area is located on fertile loam and clay flats associated with the Irwin River. In the east, it encompasses the Irwin River valley floor and the western boundary loops to the south of the …

When The Well Runs Dry: Why Water-Rich States Need To Prepare For Climate Change And Protect Their Groundwater, Danielle Takacs

William & Mary Environmental Law and Policy Review

It may seem surprising to see such concern over groundwater usage in a state like Wisconsin. While known for its dairy and cheese production, Wisconsin is first in the nation for producing snap beans and cranberries. Agriculture contributes $88.3 billion annually to Wisconsin’s economy alone. In addition to bordering two of the Great Lakes, Lake Michigan and Lake Superior, Wisconsin boasts that it is home to about 15,000 lakes. And this does not include the numerous rivers and streams throughout the state. These facts alone may make Wisconsin seem an unlikely place for disputes over groundwater, as water seems to …

Monitoring And Evaluating The Influences Of Class V Injection Wells On Urban Karst Hydrology, James Adam Shelley

Masters Theses & Specialist Projects

The response of a karst aquifer to storm events is often faster and more severe than that of a non-karst aquifer. This distinction is often problematic for planners and municipalities, because karst flooding does not typically occur along perennial water courses; thus, traditional flood management strategies are usually ineffective. The City of Bowling Green (CoBG), Kentucky is a representative example of an area plagued by karst flooding. The CoBG, is an urban karst area (UKA), that uses Class V Injection Wells to lessen the severity of flooding. The overall effectiveness, siting, and flooding impact of Injection Wells in UKA’s is …

Numerical Analysis Of A Ground-Source Heat-Pump System In Traditional Japanese “Kyo-Machiya” Dwellings, Shun Takano, Chiemi Iba, Shuichi Hokoi

International Building Physics Conference 2018

Kyo-machiya, which is a traditional wooden dwelling in Kyoto, is generally equipped with a shallow well. The well water can be potentially utilized as a heat source with a geothermal heatpump system without incurring a high drilling cost. Hereby, more energy saving in the traditional dwelling can be realized with the heat-pump system. However, an appropriate technique to utilize geothermal heat from a shallow well has not been established yet in Japan. To promote the geothermal use, we have continued an experiment to evaluate the practicability of a simple geothermal heat-pump system installed in a shallow well since the winter …
