  • Simulating vegetation shifts and carbon cycling in Yosemite National Park

    Creator:
    Conklin, David R.
    Abstract:
    The vegetation in Yosemite National Park changed during the 20th century and may change in the 21st century in response to climate change. Vegetation surveys made during the 1930s and the 1990s provide benchmark records separated by 60 years. This study uses the MC1 dynamic global vegetation model to forecast...

  • OME : A Framework for Running Spatially Explicit System Dynamics Models

    Creator:
    Wingo, Patrick C.
    Abstract:
    The Open Modeling Environment (OME) is a tool developed to address some known shortcomings in ecological System Dynamics (SD) modeling research. OME provides a common set of methods for interacting directly with spatial information, reducing the need for modelers to create their own methods for doing so. The environment is...

  • Modeling the Influence of Wildfire Management Networks in Social-Ecological Systems

    Creator:
    Avila, Colton C.
    Abstract:
    Wildfire management networks allow for collaborative intervention in mitigating the ever-present risk of major wildfire events. This thesis consists of two manuscripts that explore the topology and characteristics of wildfire management networks and their ability to influence wildfire severity in social-ecological systems. The first manuscript focuses on the characteristics of...

  • Optimal irrigation management : a framework, model, and application for optimizing irrigation when supplies are limited

    Creator:
    Hillyer, Charles C.
    Abstract:
    Many regions in North America are experiencing water shortages, and these conditions are expected to worsen. The next generation of irrigation scheduling applications must therefore be capable of providing operational advice in support of deficit irrigation strategies. However, the theoretical, technical, and practical challenges associated with deficit irrigation scheduling are...

  • Traffic and greenhouse gas modeling in future land use development scenarios of Skagit County

    Creator:
    Mooney, Abraham A.
    Abstract:
    Energy use and greenhouse gas emissions are on the forefront of planning policy in the world today. In the U.S., the transportation sector accounts for 50 percent of greenhouse gas (GHG) emissions, the most of any single sector. State and local levels of government have been very proactive in the...

  • Sensitivity analysis of the Catchment Modeling Framework (CMF) and use in evaluating two agricultural management scenarios

    Creator:
    Metta, John W. P.
    Abstract:
    Abstract Watershed-scale fate/transport modeling of contaminants is a tool that scientists and land managers can use to assess pesticide contamination to stream systems. The Catchment Modeling Framework (CMF) is a catchment-scale fate/transport modeling tool. It was developed to help scientists and land managers assess the effects of possible land-use decisions...

  • New tools and approaches to uncertainty estimation in complex ecological models

    Creator:
    Brugnach, Marcela
    Abstract:
    This dissertation investigates the problem of uncertainty in complex ecological models. The term "complex" is used to convey both the common and scientific meanings. Increasingly, ecological models have become complex because they are more complicated; ecological models are generally multi-variate and multi-leveled in structure. Many ecological models are complex because...

  • Development and evaluation of multiple criteria decision-making approaches to watershed management

    Creator:
    Lamy, France
    Abstract:
    Decision-making in environmental management is complex due to the multiplicity arid diversity of management objectives and technological choices. This suggests that modelers and experts could utilize (I) multiple-criteria decision-making (MCDM) approaches to assist stakeholder groups in integrating and synthesizing relevant data and information to address ecological and socio-economic concerns and...

  • Model assessment of the effects of land use change on hydrologic response

    Creator:
    Vache, Kellie B.
    Abstract:
    The effect of landuse change on the hydrologic, biogeochemical and ecological response of watersheds is a concern throughout the world. To help characterize the potential magnitude of such changes, and of the potential to remediate or avoid undesirable features, studies focused on the cumulative watershed effects of site level change...

  • The development and analysis of future agricultural landscapes

    Creator:
    Berger, Patricia A.
    Abstract:
    Alternative futures studies provide a way for policy-makers and stakeholders to investigate the future impacts of different management strategies by providing representations of possible outcomes. An alternative futures study was undertaken by the Pacific Northwest-Ecosystem Research Consortium for the Willamette River Basin, Oregon, USA, to determine how this regional system...
