Adaptation And Sustainability In A Small Arctic Community: Results Of An Agent-Based Simulation Model, Matthew Berman, Craig Nicolson, Gary Kofinas, Joe Tetlichi, Stephanie Martin

Craig Nicolson

Climate warming and resource development could alter key Arctic ecosystem functions that support fish and wildlife resources harvested by local indigenous communities. A different set of global forces—government policies and tourism markets—increasingly directs local cash economies that communities use to support subsistence activities. Agent-based computational models (ABMs) contribute to an integrated assessment of community sustainability by simulating how people interact with each other and adapt to changing economic and environmental conditions. Relying on research and local knowledge to provide rules and parameters for individual and collective decision making, our ABM generates hypothetical social histories as adaptations to scenario-driven changes in …

A Watershed-Based Classification System For Lakes In Agriculturally-Dominated Ecosystems: A Case Study Of Nebraska Reservoirs, Henry N. N. Bulley

Department of Geography: Dissertations, Theses, and Student Research

In recent decades substantial progress has been made in improving the quality of surface waters in the United States (Hawkins et al., 2000; EPA, 2000; EPA, 2001); nevertheless, much work remains to be done in assessing the state of impairment of lake waters. Impairment implies that the existing water quality of a lake, as measured by selected criteria (e.g., nitrogen, phosphorus, chlorophyll-a, Secchi depth), exceeds a threshold value or standard that presumably reflects optimal attainable lake water quality conditions (or "reference" conditions) (Hughes, 1995; EPA, 2000; EPA, 2001). Such impaired waters are not suitable for designated uses such as drinking, …

The Value Of Created Dunes To Address Coastal Hazards In Chesapeake Bay: Hurricane Isabel Impacts, C. Scott Hardaway Jr., Donna A. Milligan, Travis R. Comer

Reports

Perhaps the most important function of a created dune, from some perspectives, is coastal protection. Since the initiation of this subtask within the overall Chesapeake Bay Dune Monitoring and Management Analysis project, Hurricane Isabel impacted the coastal plain of Virginia and significantly altered almost all Bay shorelines to one degree or another. This is particularly true of shorelines facing north, east, and south since the winds shifted as the storm passed. The original task scope has changed slightly as a result of Isabel’s passage since it was such a significant storm event and provided an opportunity to show how dunes …

Subterranean Loss And Gain Of Water In Mountain Lake, Virginia: A Hydrologic Model, Martin Jansons, Bruce C. Parker, Jacob E. Waller

Virginia Journal of Science

Mountain Lake, Virginia is a small, unique, oligotrophic, subalpine ecosystem in the southern Appalachians. Previous studies have disclosed that this lake has manifested periodic prolonged low water levels during the several thousand years of its existence. The most recent low water level occurred during the drought years of 1999-2002. Measurements of lake level, precipitation, and other meteorological data including calculated evapotranspiration in the lake basin from 2/19/02 to 8/31/03 have enabled estimation of net subterranean water losses presumably through cracks between Clinch sandstone boulders and/or the recently discovered deep hole at the northwest end of Mountain Lake. These net losses …

Reducing Nutrient Discharge From Agriculture Through The Implementation Of Bmps – How Far Can We Go?, David Weaver, Simon Neville, Robert Summers, Martin Clarke

Conference papers and presentations

Algal blooms in south west Western Australia are a symptomatic response to excess nutrient input. Whilst a range of Best Management Practices (BMPs) are available to address the causes of nutrient pollution, most investment has been directed towards symptoms. In order to treat nutrient pollution causes effectively it is important to evaluate possible nutrient reductions and costs, and to determine whether accrued benefits can influence BMP adoption. Models were developed for catchments near Albany (south coast of Western Australia), and for the Peel-Harvey catchment (70 km south of Perth) to estimate costs and benefits of implementing conventional BMPs in scenarios …

Bacterial Degradation Of Disinfection By-Products In Drinking Water, Laura Inga Fauntleroy

Chemistry & Biochemistry Theses & Dissertations

Chlorine became a major disinfectant for the removal of microbial contaminants in 1914. Current water chlorination procedures yield halogenated disinfection byproducts (DBPs), such as haloalkanes and haloacetic acids (HAAs), due to the reaction of chlorine with naturally occurring organic compounds. Various water utilities have observed decreased HAAs levels in maximum residence time locations (MRTLs), where they were expected to be higher. These MRTLs have low free chlorine residual and high heterotrophic bacteria plate counts. Xanthobacter autotrophicus, GJ-10, is a bacterium that has been shown to contain dehalogenase enzymes and, therefore, can biodegrade HAAs. A number of water-system bacteria were …

An Audit Of The Uptake Of Agricultural Nutrient Management Practices In The Peel-Harvey Catchment, Kelly Lavell, Robert Summers, David Weaver, Martin Clarke, John Grant, Simon Neville

Conference papers and presentations

Recent funding through the Coastal Catchments Initiative aims to significantly reduce the discharge of nutrients to the waterways of the eutrophic Peel-Harvey catchment. A range of projects within this initiative have been developed, which include activities designed to develop, test and implement point and non-point source best management practices (BMP) for the control of nutrient export, and to audit the current levels of adoption of these practices. Landholders who manage approximately 30% of the catchment area have been interviewed under major BMP themes of fertiliser management, soil amendment, perennial pastures, riparian and water management, revegetation, irrigation management and effluent management. …

The Use Of Bauxite Residue To Control Diffuse Phosphorus Pollution In Western Australia – A Win-Win-Win Outcome, Robert Summers, Mark Rivers, Martin Clarke

Conference papers and presentations

The Department of Agriculture, Western Australia has been working with Alcoa World Alumina Australia Ltd for more than ten years investigating the potential to use bauxite refining residues as soil amendments for the poor, acidic, sandy soils of the Swan Coastal Plain in south west Australia. Regional waterways, especially the Peel Inlet and Harvey Estuary, have historically been susceptible to nuisance algal blooms fed by phosphorus in run-off from farmland and urban areas. Extensive laboratory, field and catchment-scale trials have shown the ability of soil amendment with fine bauxite refining residue (now trademarked in this context as Alkaloam™) to reduce …

Release And Transport Of Nutrients From Livestock Manure Applied To Pastureland, Michelle L. Soupir, Saied Mostaghimi, Eugene R. Yagow, David H. Vaughan

Michelle L. Soupir

Land applications of manure from confined animal systems and direct deposit by grazing animals are both major sources of nutrients in streams. An understanding of the overland transport mechanisms from land applied waste is needed to improve design of best management practices and modeling of NPS pollution. Release and transport plots were established to study in-field nutrient release and transport from pasturelands receiving phosphorus based livestock waste applications. The release plots determined the concentrations available to be transported to the edge of the field in runoff. Four manure treatments (turkey litter, liquid dairy manure, standard cowpies, and none) and three …
