A Hydrology Temperature Model For A Small Mountain Watershed, Charles Wilson Pettee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A small mountain watershed located in the Wasatch Mountains of North Central Utah is calibrated to a lumped, deterministic simulation model which is capable of predicting daily streamflow and stream temperature. The input information required is daily precipitation and maximum and minimum air temperatures.

In this study, the area of watershed modeling is reviewed in general and as it specifically applies to the study watershed.

The degree of correlation between observed data and predicted output is only mediocre. The model remains unverified for streamflow prediction and is poorly verified for stream temperature.

Aspen Mortality In Rocky Mountain Campgrounds, Thomas E. Hinds

Aspen Bibliography

Aspens die from canker disease infections as a result of mechanical injuries to the live bark inflicted by thoughtless campers. Dead trees usually are cut to reduce camper hazard. Aspen loss is related to campground age. A desirable aspen-type camp unit can be degraded to a treeless site of grass, forbs, and shrubs within 10 to 20 years. The management of aspen campgrounds must be altered if the resource is to be maintained.

Perspective On Particleboards From Populus Spp., Robert L. Geimer

Aspen Bibliography

Populus species particleboards have a high compression ratio resulting in high bending strength. Their low-porosity edges, advantageous in furniture manufacture, dictate close moisture content control in production.

Aspen roundwood is the primary raw material for composition structural sheathing. Populus utilization will likely increase as material sources expand and as new product develop.

Frost Damage In Poplar On The Prairies, Harry Zalasky

Aspen Bibliography

Frost cankers in poplar are freeze-killed areas of bark and wood around which woody calluses develop and form buris and frost ribs. Frost dieback is a freeze-killed segment of the stem at the base, tip, or mid-portion of a branch or leader. It may or may not enhance natural pruning or poplar branches depending on whether the basal parts are damaged or alive and able to form abscission layers. In addition to abscission, low temperature affects increment, growth patterns, and vigor of poplar. Tree become stunted from persistent leader dieback. Suckers, crooks, and sweeps also characterize many stands of poplar. …

Bird Populations Of Aspen Forests In Western North America, J.A. Douglas Flack

Aspen Bibliography

The patterning of populations of plants and animals is probably the result of selection over time of organisms according to their individual physiological tolerances, behavioral adaptations to an environmental complex, and geographical availability (Gleason 1926).

Aspen Resource In The Southwest, Darrell W. Crawford

Aspen Bibliography

There is a relatively large source of unused aspen in the Southwest. If markets can be developed, there are challenging opportunities to utilize more of this fiber. Most aspen in the Southwest is classified in the marginal component because of steep slopes, accessibility and low market values. To meet the logging constraints of this component is a real challenge to prospective purchasers. However, commercial opportunities are feasible on the Carson, Santa Fe, Apache and Kaibab National Forests.

Aspen Forest After Harvest, Norbert V. Debyle

Aspen Bibliography

Aspen is a unique forest tree with respect to regeneration. It produces abundant root suckers, up to 40,000 per acre are common, after clearcutting or fire removes the parent stand. The rapidly growing sucker stand competes well with other vegetation, but is susceptible to destruction by excessive ungulate browsing. Clearcut areas produce more streamflow and more growth on shrubs and herbaceous vegetation than does the uncut forest. The patchwork of age classes that results from even-age management optimizes wildlife habitat requirements for several desired species.

Kiln Drying Characteristics Of Studs From Rocky Mountain Aspen And Wisconsin Aspen, James C. Ward

Aspen Bibliography

Aspen studs, 7/4-inch thick, from Rocky Mountain and Wisconsin trees will dry to required moisture contents within similar periods of time under conventional and high temperature kiln schedules. Bacterial wetwood occurs in both Rocky Mountain and Wisconsin aspen and causes severe drying problems from wet pockets, collapse, honeycomb, and ring failure. Presorting green lumber is a suggested solution to the wetwood problem.

Understory Production Not Predictable From Aspen Basal Area Or Density, K.E. Severson, J.J. Kranz

Aspen Bibliography

Analysis of effects of aspen basal area and density on production of understory vegetation revealed no useful predictive relationships using the model log Y = a + bX. However, as the proportion of ponderosa pine basal area increased in aspen-pine stands, understory production declined in a predictable manner. Root biomass, total biomass, and/or growth rate of aspen may be more closely related to understory production than measures of aspen overstory.
