A spreadsheet-based transport model was developed in Microsoft Excel™ as part of a six-year National Cooperative Highway Research Program project conducted at Oregon State University. The model simulated the leaching, transport, removal, and retardation processes that occur in the surface and subsurface pathways of the near highway environment. For all...
An integrative method for monitoring glacier geometry change and mass balance is presented and applied to the Pacific Northwest, USA. Acting as a baseline for interpretation of future changes in glacier size and shape, we first derive a new inventory of regional glacier cover using remotely sensed data. To investigate...
Every year, the United States produces at least 236 million metric tons of hazardous waste. Hazardous waste is defined as solid waste that can pose a substantial threat to human health and the environment when disposed of incorrectly. Some commonly used household products, when disposed of, become hazardous waste; historically,...
Improving the understanding the relations of sustainability behaviors in manufacturing systems and actively engaging with manufacturers (especially SMEs) in sustainability efforts is key to the long-term success of U.S. industry and the natural environment. This study addresses this urgent need by establishing a systemic approach for the design of costing...
Over the past decade, the business sector has come under increasing pressure to improve their environmental, safety, and health (ESH) performance. This pressure has stemmed from both external and internal sources with the organization. Public image, legislative and regulatory requirements, stakeholder awareness of environmental performance, sustainable development, and changing corporate...
This work describes the modeling framework and initial results for CLAWS (Coupled
Landscape And Water System), a physically-based, spatially-distributed hydrologicgeomorphic model that has been coupled with a vegetation dynamics simulation. Spatial variability of topography, soil, vegetation, and climate drive a hydrology module that calculates the water budget at given time...
Baseline data for the first year of a two-year study to assess
the current status of ponderosa pine stands in southeastern
Montana relative to coal-fired electric power development are
presented. Sixteen permanent plots in pine stands were established
in eastern Montana, South Dakota, and Wyoming. Several characteristics
believed to be...
A contingent valuation methodology was applied to old-growth forests and critical habitat units for the Northern Spotted Owl in Oregon to esimate the economic value to the public in knowing that rare and unique ecosystems will be protected from fire for current and future generations. Generalizing to the whole state,...
Cloud reflectivity is a function of cloud liquid water content and droplet number concentration. Since cloud droplets form around pre-existing aerosol particles, cloud droplet number concentration depends on the availability of particles that can serve as cloud condensation nuclei. Given constant liquid water amount, increased availability of cloud condensation nuclei...
This investigation was motivated by the introduction of the new
nearest neighbour analyses which reportedly provided a better control
of soil gradients than conventional experimental methods.
Three nearest neighbour analyses and six other analyses were
compared with the completely randomized design or the randomized
complete block design in reducing the...
