We investigate several aspects of the numerical solution of the radiative transfer
equation in the context of coal combustion: the parallel efficiency of two commonly used
opacity models, the sensitivity of turbulent radiation interaction (TRI)...

Several reports related to dams and dam removal have been released this
decade by non-governmental organizations including Dam Removal: Science and
Decision Making by The Heinz Center which focused on small dams, since most
of the dams removed to...

Greater sage-grouse (Centrocercus urophasianus), a sagebrush obligate species,
has contracted in extent by nearly half its original distribution. This is primarily due to
habitat loss and degradation over the past 150 years. During winter,...

A study of the temporal and spatial variability of stream gravel bed
composition and the factors affecting the amount of fine sediment within
the bed was conducted in the streams of the Oregon Coast Range.
Streambed samples were obtained by frozen...

This study concerns the use of a discrete-event
simulation model for analyzing the production of a
mechanized forest harvest system. The simulation models a
field collection data set of a harvester-forwarder system
which was previously collected...

Investigations about the feeding ecology of a consumer
can facilitate prediction of its effects on prey populations
and the biological community. The aspects of feeding
ecology that are important to predicting consumer effects
include foraging...

Implements for tilling compacted forest soils were
tested on sites logged with ground-based machines in
Oregon. The sites covered a variety of soil conditions
ranging from a clay loam to a rock7 2C2 iplemeflts
