Groundwater Chemistry Of The Weaber Plain: Preliminary Results, Adam Lillicrap, Paul Raper, Richard J. George Dr, D L. Bennett
Resource management technical reports
In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain. Construction of the M2 supply channel connecting the ORIA and the Weaber Plain, and the final period of irrigation design, environmental management and related approval processes, commenced later in 2009. This process followed a protracted period of public and private industry planning and environmental assessment (Kinhill 2000). This report summarises an analysis of groundwater salinity trends on the Ivanhoe and Weaber plains and the preliminary results of an intensive water-quality sampling program carried out in 2010 as part …

Assessing Flood Inundation Mapping With The Use Of A Dem And Gis Along The Missouri River At Sioux City, Iowa, Kathryn A. Pfaffle
Department of Environmental Studies: Undergraduate Student Theses
There are various methods that are used to predict flood inundation. The U.S. Army Corps of Engineers provided inundation maps for the 2011 Missouri River flood event that did not utilized aerial photo imagery. This study assesses the suitability of using a digital elevation model (DEM) in combination with aerial photo imagery within a geographic information system to predict flood inundation mapping along the Missouri River in Sioux City, Iowa. GPS data was collected during the height of this flood event in order to validate the positional accuracy of the DEM. Using the GPS receiver’s accuracy standards to determine the …

This report assembles and reviews all available physico-chemical water quality data for the lower Keep River and Border Creek systems and presents data from the initial year of a targeted baseline monitoring program (June 2010 – June 2013).
Multiple Storm Event Impacts On Epikarst Storage And Transport Of Organic Soil Amendments In South-Central Kentucky, Sean M. Vanderhoff
Multiple Storm Event Impacts On Epikarst Storage And Transport Of Organic Soil Amendments In South-Central Kentucky, Sean M. Vanderhoff
Masters Theses & Specialist Projects
The groundwater in agricultural karst areas is susceptible to contamination from organic soil amendments and pesticides. During major storm events during 2011, dye traces were initiated using sulphorhodamine-B, fluorescein and eosine in a groundwater recharge area where manure was applied to the ground. Fecal coliform samples were collected from significant storm events from January-September 2011. Water samples and geochemical data were collected every four hours before, during, and between the storm events from a waterfall in Crumps cave flowing from the known recharge area to track the transport and residence time of the epikarst water and organic soil amendments during …
The Effects Of Evapotranspiration Upon Recharge Using The Stable Isotopes Of Oxygen And Hydrogen In The Carbonate Aquifers Of The Cumberland Plateau In Southeast Kentucky, Lee J. Florea
Lee J Florea, PhD, P.G.
In this brief manuscript, we consider the variation of the stable isotopes of oxygen, δ18O, and hydrogen, δ2H, in samples collected during 2010 and 2011 from precipitation and shallow groundwater along the Cumberland Plateau of southeast Kentucky. These data from the 1,900-ha Redmond Creek karst aquifer lend insight into the source and timing of recharge to shallow groundwater in the epigenic karst of the U.S midcontinent. Specifically, we find that only 43% of precipitation remains as potential recharge after accounting for evapotranspiration, and 85% of this potential recharge occurs during only four two-week sampling periods. The isotopic composition of precipitation …

Quantification Of Nitrate Sources And Sinks Using A Water Quality Network In Morro Bay Estuary, California, Johanna Nadia Jean Weston
Master's Theses
Using an instrumented water quality network in Morro Bay Estuary, California from 2007 to 2010 (15 min sampling frequency), this study addressed the two objectives of constructing a nitrate budget and assessing the influence of sampling frequency on water quality parameters. These two objectives led to the submission of an original report of research (Appendix A) and a note (Appendix B) to peer-reviewed journals.
The first objective was to characterize the high spatial and temporal variation in physical parameters and nitrate concentrations and to construct a nitrate budget quantifying sources and sinks of nitrate from the ocean, streams, and groundwater, …

Depositional Fluxes And Concentrations Of 7Be And 210Pb In Bulk Precipitation And Aerosols At The Interface Of Atlantic And Mediterranean Coasts In Spain, R. L. Lozano, E. G. San Miguel, J. P. Bolívar, M. Baskaran
Environmental Science and Geology Faculty Research Publications
Bulk depositional fluxes of 7Be and 210Pb in precipitation measured over a period of 16 months (April 2009–July 2010) in Huelva, Spain varied between 5.6 and 186 Bq m−2 month−1 (annual mean: 834 Bq m−2 year−1) and 0.8 and 8.1 Bq m−2 month−1 (annual mean: 59 Bq m−2 year−1), respectively, with the lowest depositional fluxes occurring during dry summer months. Quantitative evaluation of the precipitation-normalized seasonal depositional fluxes of 7Be and 210Pb indicates that the enrichment factor in winter is < 1.0 while in 2010 spring, it is significantly higher than 1, possibly indicating input of air from the stratosphere-troposphere exchange (for 7Be). The specific activities of …

Soil Assessment Of The Weaber Plain (Goomig) Farmlands, Henry Smolinski, Justin Laycock, Jim Dixon
Resource management technical reports
In 2008, the Ord Irrigation Expansion Project was approved by the Western Australian Government to develop irrigated agriculture on the Weaber Plain (Goomig)
As part of the environmental planning and approvals process, the WA Government was required to prepare a groundwater management plan and a hydrodynamic plan.
As a result, the Department of Agriculture and Food, Western Australia (DAFWA) was requested to lead an investigative program to support a second phase of modelling. The project was divided into five components: two addressing deficiencies related to groundwater, two relating to soils and subsoils, and one addressing surface and groundwater quality aspects. …

Development Of An Approach To Evaluate Fractured Crystalline Bedrock Water Resource Supply And Sustainability, Helen E. Spera
Master's Theses
Groundwater derived from fractured crystalline bedrock is an important resource in Connecticut. Despite its importance we know very little about this resource. This study was conducted at the Plant Science and Landscape Architecture Research and Education Facility, University of Connecticut, Storrs, CT. The objectives of this study were: to improve the characterization of the hydrogeology of the facility; to develop a method to determine the amount of recharge to the bedrock from the overburden during pumping and non-pumping periods; and to develop an approach that can be used in evaluating the sustainability and zone of contribution of bedrock pumping wells. …
Determining The Viability Of A Hybrid Experiential And Distance Learning Educational Model For Water Treatment Plant Operators In Kentucky, Jana R. Fattic
Determining The Viability Of A Hybrid Experiential And Distance Learning Educational Model For Water Treatment Plant Operators In Kentucky, Jana R. Fattic
Masters Theses & Specialist Projects
Drinking water and wastewater industries are facing a nationwide workforce shortfall of qualified treatment plant operators due to factors including the en masse retirement of baby boomers and the tightening of regulatory requirements regarding the hands-on experience required prior to licensure. Rural areas are hardest hit due to the lack of educational and experiential opportunities available to them within a reasonable proximity. Using a variety of demographic and industry data, a geographic analysis of Kentucky was conducted to assess the viability of the traditional classroom delivery model versus a hybrid experiential and distance learning educational model (HEDLEM). Although this analysis …
Groundwater Contamination Potential In Northern Nevada From Mining, Associated Communities, And Agriculture As Forecasted By Two Vulnerability Methods, John L. Swatzell
Groundwater Contamination Potential In Northern Nevada From Mining, Associated Communities, And Agriculture As Forecasted By Two Vulnerability Methods, John L. Swatzell
UNLV Theses, Dissertations, Professional Papers, and Capstones
Two methodologies, DRASTIC and the NDEP method, were used to compare the groundwater vulnerability of mining, associated towns, and agricultural areas in northern Nevada. The DRASTIC and NDEP methods were compared to determine which method produces a more accurate depiction of vulnerability. Vulnerability maps were created using the United States Environmental Protection Agency's (USEPA) DRASTIC and Nevada Department of Environmental Protection (NDEP) methodologies. The DRASTIC map uses seven aspect layers of geologic and hydrologic information with assigned values and weights that are applied to a mathematical equation. The NDEP method uses field data collection for potential contaminant sources and well …

Competition for scarce Colorado River water resources is nothing new, but the conflicts that prompted the seven basin states to negotiate the 1922 Colorado River Compact have grown considerably fiercer and more complex in recent decades. In 2007, responding to the challenges of increasing demand and sustained drought, the seven basin states and a number of other affected interests agreed to a set of interim guidelines for allocating Colorado River water in the event of shortages. This agreement represents an important evolution in the governance of the Colorado River, suggesting that the many interests in the basin can work together …
