The timely development of the nation's energy production capacity in a manner that minimizes potential adverse local and regional impacts associated with energy facilities requires the use of sophisticated techniques for evaluation of siting alternatives and fuel cycle options. This report is a documentation of the computerized SITE methodology that has been developed for evaluating health, environmental, and socioeconomic impacts related to utilization of alternate sites for energy production within a region of interest. The cost, impact, and attribute vectors, which are generated and displayed on density maps, can be used in a multiparameter overlay process to identify preferable siting areas. The assessment of...
Spatial and temporal mismatches between coarse resolution projections of global climate models (GCMs) and fine resolution data requirements of ecosystems models are the major obstacles for assessing the site-specific climatic impacts of climate change on natural resources and ecosystems. The objectives of this study were to: (i) develop a simple method for statistically downscaling GCM monthly output at the native GCM grid scale to station-scale using transfer functions, and (ii) further demonstrate the site-specific impact assessment of climate change on water resources, soil erosion, and crop production at Kingfisher, OK, US using the water erosion prediction project (WEPP) model. Monthly precipitation and temperature...

The PFLCC has recently completed a set of comprehensive conservation planning scenarios for the state of Florida. This represents the first statewide effort to assess likely alternative futures for conservation considering an array of financial, biological, climatological and urbanistic conditions. These spatially explicit and temporal scenarios simulate both urban growth and climate change and identify the most suitable areas for conservation given the resulting land use pattern. Conservation allocations are based on both fee-title and conservation easements.The conservation priorities and mechanisms expressed in these scenarios are based on a wide set of contributing factors, and simulated conservation is purposefully...

With joint funding from the North Central Climate Science Center (NC CSC) and NASA's Earth Science Applied Sciences Program, the NC CSC supports resource managers and their decision process through its Resource for Vulnerability Assessment, Adaptation and Mitigation Planning (ReVAMP), a collaborative research/planning effort supported by high performance computing and modeling resources. The NC CSC focuses primarily on climate data as input to the ReVAMP. In this project the NASA DEVELOP program was used to evaluate how remote sensing data sets can contribute to the ecological response models that are implemented in the ReVAMP system. This work demonstrates the utility of remote sensing in vulnerability assessment...

Small mammal populations were live-trapped at two campsites and two control areas along the Colorado River in Canyonlands National Park, Utah, to determine the effects of camping impact on small mammal numbers. Data were collected from August 20 to September 10, 1976, and from April 11 to September 10, 1977. Captures of the canyon mouse (Peromyscus crinitis), least chipmunk (Eutamias minimus), antelope ground squirrel (Ammospermophilus leucurus), white-throated wood rat (Neotoma albigula) and rock squirrel (Spermophilus variegatus) populations were numerous enough to permit statistical comparison. At the Brown Betty campsite, small mammal populations, with the exception of rock squirrels, increased with campsite...
The process whereby hydrogeologists interpret the available information to produce a justifiable set of simplifying assumptions to describe a groundwater system is called conceptual modelling. Although this process is inherent in all hydrogeological assessments and can therefore be regarded as synonymous with hydrogeological practice there are no standard specifications for it. A framework for conceptual modelling has been designed to both assist in the planning and process of the work and to provide an audit trail to facilitate independent scrutiny. The application of this framework is illustrated by two case histories, one of a small-scale investigation for a proposed cemetery and the other of an investigation...

* The PFLCC, in conjunction with GeoAdaptive (GA) and Geodesign Technologies (GDT), completed a set of comprehensive conservation planning scenarios for the state of Florida in 2014. The scenarios considered variations in climate change, urban growth, conservation funding, and conservation strategy and were designed using a stakeholder-based process involving both the science advisory board and steering committee of the PFLCC. This represents the first statewide effort to assess likely alternative futures for conservation considering an array of financial, biological, climatological, and urban growth pattern conditions. Land use and land tenure changes were simulated to systematically allocate potential future conservation...

Evaluation criteria for reservoir and stream resources were developed to provide decision makers with feedback on environmental consequences of water allocation decisions under conditions of severe sustained drought within the Colorado River Basin by using the AZCOL gaming simulation model. Seven categories of flow dependent resources were identified which highlight resource states associated with reservoirs or river reaches within the AZCOL model. AZCOL directly simulates impact of water management decisions on five resource categories: threatened, endangered or sensitive fish; native nonlisted fish; wetland and riparian elements; national or state wildlife refuges; and hatcheries or other flow dependent facilities....
Trends and uncertainty of the climate change impacts on hydrology, soil erosion, and wheat production during 2010–2039 at El Reno in central Oklahoma, USA, were evaluated for 12 climate change scenarios projected by four GCMs (CCSR/NIES, CGCM2, CSIRO-Mk2, and HadCM3) under three emissions scenarios (A2, B2, and GGa). Compared with the present climate, overall t-tests (n = 12) show that it is almost certain that mean precipitation will decline by some 6% (>98.5% probability), daily precipitation variance increase by 12% (>99%), and maximum and minimum temperature increase by 1.46 and 1.26 °C (>99%), respectively. Compared with the present climate under the same tillage systems, it is very likely (>90%) that evapotranpiration...

This project utilizes projected visualization of land cover conditions for the state of Florida at three future time periods. Simulated projected future conditions also vary by patterns in development, levels and types of conservation, and sea level rise. These visualized scenarios afford the opportunity to examine a range of possible outcomes for land use and land cover, and use these scenarios to evaluate the impacts on potential habitat distributions for focal species. For this project, focal species were centered within the Florida Panther National Wildlife Refuge and impacts. The methodology for this project includes four major steps, which have been found to be effective in previous scenario analyses with...

Permafrost is a layer of perennially frozen soil that primarily exists in and around the Arctic and Antarctic regions of the world. While a shallow near-surface soil layer (called active layer) thaws during the summer and re-freezes in the winter, the underlying permafrost remains perennially frozen, often underlying buildings, roads, and other infrastructure. As warmer temperatures become more common, thawing of permafrost could have major consequences for Alaska. Where thawing has already occurred, dramatic changes in ecosystems and existing infrastructure are evident. For example, thawing permafrost along the ocean shore and riverbanks in Northern Alaska is causing substantial coastal erosion and is impacting...

This report presents the results of a social cost evaluation of three prospective photovoltaic electricity supply technologies. The technologies--based on cadmium sulfide, silicon, and gallium arsenide--are compared with each other and with coal in three categories of direct social impacts: occupational and public health and environmental effects. Indirect impacts, due to opportunity costs and benefits, or to health or other effects of use of material, labor or energy itself, are also considered. Special attention is given to regulatory issues that will arise in connection with these social costs and to their potential importance to government programs and commercial development.
