Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham Dec 2009

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham

Masters Theses & Specialist Projects

Agriculture contamination is very common in karst systems due to the vulnerability of these aquifers. Animal waste is often spread across crop land to enrich the soil with nitrates and phosphates. Herbicides and pesticides are also applied to the crops. The transport of these pollutants through the soil and epikarst is a difficult process to monitor due to the complex, heterogeneous behavior of the groundwater as it makes its way down to the aquifer below.

An experimental site at Crumps Cave lended a unique opportunity to monitor the vadose zone at a waterfall in the cave below. A previous dye …

Agenda: Best Practices For Community And Environmental Protection, University Of Colorado Boulder. Natural Resources Law Center. Intermountain Oil And Gas Bmp Project, Colorado. Oil And Gas Conservation Commission

Best Practices for Community and Environmental Protection (October 14)

The first Intermountain BMP Project workshop, sponsored by the Natural Resources Law Center and the Colorado Oil and Gas Conservation Commission, was held in Rifle, Colorado on October 14, 2009 at the Garfield County Fairground for over 170 participants.

Speakers from Federal, state and local governments, the community, industry and environmental consultants, and conservation groups focused presentations and discussion on a greater understanding of what Best Management Practices (BMPs) are appropriate to the western slope of Colorado and how they are integrated into developments.

Interagency Management Action Plan (I-Map) For Quagga Mussels, David Wong, Shawn Gerstenberger

Public Lands Institute Publications

Following the discovery of quagga mussels in Lake Mead, a variety of agencies, including National Park Service (NPS) Lake Mead National Recreational Area (LMNRA), Bureau of Reclamation (USBR), Southern Nevada Water Authority (SNWA), Nevada Department of Wildlife (NDOW), U.S. Fish and Wildlife (USFWS), Clean Water Coalition (CWC), and U.S. Geological Survey (USGS) have set up monitoring programs to evaluate and gain information to help minimize the impacts or potential impacts of quagga mussels to their facilities and lake ecology. Current monitoring activities and anticipated environmental impacts are depicted in Figures 1 and 2. While the agencies have worked closely and …


Point And Nonpoint Source Analysis Of Nutrients, Metals, And Pathogens In The Sediment And Water Column In Las Vegas Wash, Christine Simmons, Kumud Acharya Aug 2009

Point And Nonpoint Source Analysis Of Nutrients, Metals, And Pathogens In The Sediment And Water Column In Las Vegas Wash, Christine Simmons, Kumud Acharya

Undergraduate Research Opportunities Program (UROP)

Formerly an ephemeral watercourse, Las Vegas Wash is now a perennial system due to urban runoff and wastewater treatment plant (WWP) effluent. Las Vegas Wash flows into Lake Mead, where the discharge point is only a few miles upstream of Las Vegas’ main water intake. This small water cycle establishes the necessity to evaluate water quality especially due to non point sources pollution, wherein my research lies. Several points along Las Vegas Wash upstream and downstream of WWP have been chosen to represent different landuse types such as commercial, residential, wastewater treatment plants, etc. At each location, parameters including arsenic, …


Esperance Area Acid Sulfate Soil Hazard Mapping, Paul Galloway, Simon Clarendon Aug 2009

Esperance Area Acid Sulfate Soil Hazard Mapping, Paul Galloway, Simon Clarendon

Resource management technical reports

This project created a regional scale (1:100 000) acid sulfate soil (ASS) hazard map for the Lake Warden and Esperance town areas, using a combination of existing soil-landscape mapping information and elevation data, supported by field observations and laboratory data from 18 soil cores and 29 additional borelogs with descriptive information useful for identifying ASS and potential ASS materials. All data gathered during this project used common standards and protocols developed in Australia for identifying and mapping ASS materials. The project extends the mapping for acid sulfate soil in the region, complementing existing maps compiled for other parts of the …


Fisheries Research Report No. 194 - Conceptual Models For Ecosystem Based Fisheries Management (Ebfm) In Western Australia, Sarah J. Metcalf, D J. Gaughan, Jennifer Shaw Aug 2009

Fisheries Research Report No. 194 - Conceptual Models For Ecosystem Based Fisheries Management (Ebfm) In Western Australia, Sarah J. Metcalf, D J. Gaughan, Jennifer Shaw

Fisheries Research Reports

The Department of Fisheries, Western Australia is currently developing a framework to assess the most appropriate methodologies for the implementation of Ecosystem Based Fisheries Management (EBFM) in Western Australia. The implementation of EBFM can be considered as an operational extension of Ecologically Sustainable Development (ESD), the principles of which were adopted by Western Australia for application in the management of fisheries in 2002. EBFM aims to assess and manage ecological impacts as well as social and economic outcomes related to fish and fisheries at a regional level. The degree to which EBFM will be implemented in terms of activities or …


Fisheries Management Paper No.245 - Aquaculture Of Coral, Live Rocks And Associated Products. Aquaculture Policy, Department Of Fisheries, Western Australia Aug 2009

Fisheries Management Paper No.245 - Aquaculture Of Coral, Live Rocks And Associated Products. Aquaculture Policy, Department Of Fisheries, Western Australia

Fisheries Management Papers

Aquarium enthusiasts use corals, live rock and associated products (e.g. live sand) for display and to maintain healthy water quality conditions in their marine aquariums. There is a large and growing market for these products. While the wild harvest fisheries for aquarium products in Western Australia are sustainably managed, output is capped, so increased product is needed to meet the market demand. With a trend towards the capping of wild harvest and additional pressures, such as the introduction of Marine Parks and other marine protected areas, the aquaculture of these products is set for industry development and expansion.

The large …


Increasing The Reliability Of Ecological Models Using Modern Software Engineering Techniques, Robert M. Scheller, Brian R. Sturtevant, Eric J. Gustafson, Brendan C. Ward, David J. Mladenoff Jul 2009

Increasing The Reliability Of Ecological Models Using Modern Software Engineering Techniques, Robert M. Scheller, Brian R. Sturtevant, Eric J. Gustafson, Brendan C. Ward, David J. Mladenoff

Environmental Science and Management Faculty Publications and Presentations

Modern software development techniques are largely unknown to ecologists. Typically, ecological models and other software tools are developed for limited research purposes, and additional capabilities are added later, usually in an ad hoc manner. Modern software engineering techniques can substantially increase scientific rigor and confidence in ecological models and tools. These techniques have the potential to transform how ecological software is conceived and developed, improve precision, reduce errors, and increase scientific credibility. We describe our re-engineering of the forest landscape model LANDIS (LANdscape DIsturbance and Succession) to illustrate the advantages of using common software engineering practices.

Use Of Co2 Concentration Difference Or Co2 Balance To Assess Ventilation Rate Of Broiler Houses, Hongwei Xin, Hong Li, Robert T. Burns, Richard S. Gates, Douglas G. Overhults, John W. Earnest Jul 2009

Use Of Co2 Concentration Difference Or Co2 Balance To Assess Ventilation Rate Of Broiler Houses, Hongwei Xin, Hong Li, Robert T. Burns, Richard S. Gates, Douglas G. Overhults, John W. Earnest

Biosystems and Agricultural Engineering Faculty Publications

Ventilation rate (VR) is one of the two key elements for quantifying aerial emissions from animal production facilities. Direct, continuous measurement of building VR can be challenging and impractical under certain circumstances,e.g., naturally ventilated animal housing or a large number of ventilation fans in the building. This study examined the suitability of estimating VR of broiler houses with built‐up litter (mixture of manure and bedding), when supplemental heating was not in use, through either carbon dioxide (CO2) balance or the relationship of VR to CO2 concentration difference between exhaust and inlet air. The reference VR was based …
