Microcomputer simulation for subsurface water potential on hillslope

Creator:: Malstaff, Greg
Abstract:: This research paper focuses upon subsurface flow because of its dominant influence on the other types of hilislope water flow processes. The basic theory of water movement is quickly discussed in order to build the reader's general background knowledge. With this background, the journey starts into the poorly understood realm...

A channel stability inventory for two streams on the eastern slopes of the Coast Range, Oregon

Creator:: Sachet, James A.
Abstract:: Stream channel stability for two tributaries of Rock Creek in the Oregon Coast Range is evaluated by application of a Stream Reach Inventory. Stability nomographs are constructed for graphical analysis of erosion potential. Results indicate that channel stability can be classified. One stream is rated as 'Poor' in resistance to...

A geographic information system and hydrophysical evaluation watershed analysis methodology: Ribeira da Boca Larga, Santiago Island, Republic of Cape Verde

Creator:: Riegelmann, Edward A.
Abstract:: The Cape Verde Islands, off the coast of West Africa, are subject to violent precipitation events that cause extensive soil erosion and degradation of the landscape. A systematic approach to the collection, analysis, and dissemination of hydrophysical and geographic data was needed to effectively analyze the cause and effect variables...

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...

The origin and characteristics of soil mounds and patterned ground in North Central Oregon

Creator:: Nelson, Clark A.
Abstract:: Sections of the landscape in north central Oregon are dominated by numerous soil mounds surrounded by stone rings. Mounds vary in size and shape depending on slope and mound density. Internal soil mass is free of stones to the bedrock level and is covered by successive layers of volcanic ash....

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...

Evaluation of a basic GIS for mapping and monitoring cultural resources at the River's End Ranch, Lake County Oregon

Creator:: Marker, Mason K.
Abstract:: The use of Geographic Information Systems (GIS) is rapidly expanding in almost every field of inquiry. The field of Archaeology is also learning to use GIS to improve both initial data collection in the field and data analysis in the lab. This paper evaluates the usefulness of the GIS software...

Cirque orientation in the major highlands of Oregon

Creator:: McEwan, Duncan
Abstract:: Cirque aspects and elevations in the major highlands of Oregon indicate a pattern of climate during the Pleistocene similar to that of today. Mean cirque floor elevation increases toward the drier interior. Concentrations of cirques facing northeast, and steep gradients of cirque floor trend surfaces to the southwest, indicate a...

Landsliding processes occurring on a McDonald-Dunn Forest hillslope

Creator:: Shively, David D.
Abstract:: Landslide processes occurring on a hillslope in McDonald-Dunn Forest on the eastern slope of the Oregon Coastal Range are described in terms of type, magnitude. minimum age and site characteristics. Debris flows and debris avalanches are the dominant types of slope movement occurring in the study area. Landslide events classified...

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...
