The geomorphic significance of log steps in forest streams of the Oregon Coast Range

Creator:: Marston, Richard A.
Abstract:: A log step develops when large woody debris extends across the active channel, creating a change in the water surface elevation as the stream spills over the log step. By forming a series of vertical falls, log steps reduce the amount of potential energy available for conversion to kinetic energy...

Morphometric properties of nivation hollows on Hart Mountain, Lake County, Oregon

Creator:: Rademacher, Christopher L.
Abstract:: Hart Mountain is a basaltic fault block mountain in the semi-desert region of the northern Basin and Range province in south-central Oregon. Geomorphic processes associated with lingering snowpatches have formed nivation hollows, which are small scale depressions in the hillsides. The lingering snow in the hollows prohibits shrub growth. Bedrock...

A hierarchal approach to wind power potential evaluation at Prairie Peak, Oregon

Creator:: Woolley, Stuart G.
Abstract:: A hierarchical approach to the assessment of wind power site potential at Prairie Peak, Oregon, is evaluated. Maps, aerial photographs, and terrestrial photographs are utilized. Data are derived from photographs of wind flagged trees with the aid of an interactive computer program. The technique produces a map of isotachs, lines...

Hillslope mass movements and environmental relations - Moss Creek, Oregon

Creator:: Stauch, Carola A.
Abstract:: A slide inventory was conducted for a small watershed in the northern Oregon Coast Range. Data on geology, topography and climate were used to evaluate land stability in the Moss Creek basin. As expected, a strong correlation with slope steepness was shown. In addition, failures predominantly occurred on slopes with...

Soil mounds and patterned ground of the Lawrence Memorial Grassland Preserve

Creator:: Johnson, Colleen Burch
Abstract:: The Lawrence Memorial Grassland Preserve, located in Wasco County, Oregon, exhibits a wide variety of soil mounds and patterned ground features. The size, shape, and distribution of several elements of this peculiar landscape were analyzed with a detailed map, field observations, and statistical procedures. Common soil mound shapes are circular,...

Increasing the usefulness of high-altitude color infrared photography for the inventory, monitoring, and management of western wildland resources

Creator:: Colwell, Robert R.
Abstract:: This report describes the latest in a series of studies sponsored by the Nationwide Forestry Applications Program. Each such study has attempted to enhance the interpretability of remotely-sensed imagery. In this case the image type of specific interest is high-altitude color infrared (CIR) photography. This is a resource management tool...

The measurement of scenic preferences: a case study in Alaska

Creator:: Karle, David Anthony
Abstract:: The semantic differential technique was used to quantify four interest groups' perceptions of twenty-six Alaskan scenes. The scenes represented both panoramic views and views of Mount McKinley from different sites in southcentral Alaska. The perceptions were measured on six semantic scales ("ugly-beautiful", "dislike-like", "unpleasantpleasant", "unstimulating-stimulating", "level-mountainous", and 'monotonous-varied"), and the...

A study of the geomorphological processes at the Siltcoos foredune breaching experiment site

Creator:: Hanna, James M.
Abstract:: The focus of this study was to examine and record the physical changes brought about by the breaching of the Siltcoos Foredune. The origin of the dunes and the physical processes that operate there must be considered before effects due to the breach can be studied. A series of field...

An Investigation of Photographic Band-Ratioing

Creator:: Fisher, Scott William
Abstract:: A photographic band-ratioing technique was investigated. The data source consisted of 70 mm Landsat Multispectral Scanner (MSS) negatives. The process would require combining registered positive and negative transparencies to achieve a ratio modulation in the resulting print. This would also require compensation for atmospheric effects on the original negatives by...

Glacial landforms on snow peak in the Western Cascade Mountains of Oregon

Creator:: Hruska, John L.
Abstract:: Pleistocene glaciation in the upper elevations of the Western Cascade Mountains took two characteristic forms: cirque and valley glaciers. Field observations in the Neal Creek and Thomas Creek drainage areas of Snow Peak provide evidence of three glacial advances. Glacial landforms in the Neal Creek Valley are dominated by a...
