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...

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...

Landslide hazards in The Dalles, Wasco County, Oregon

Creator:: Sholin, Michael Hugh
Abstract:: Human activity has led to the reactivation of portions of a Pleistocene landslide complex in The Dalles, Oregon. Slope movements are in rocks of the Chenowith formation: agglomerate, conglomerate, tuff breccia, sandstone, and siltstone. Slope movements occur in at least two distinct areas in The Dalles. At one, the shear...

Deterministic landslide stability analysis: an example from NW Oregon

Creator:: Lumban-Tobing, Pago
Abstract:: A slope stability map is created for the Astoria Basin, northwestern Oregon. The stability analysis is based upon a topographically based model, TOPOG model. The model predicts the occurrence of subsurface water-logging which reduces the shear-strength of a slope-profile. Simply stated, subsurface saturated zones occur wherever the local drainage flux...

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...

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...

A comparison of false color composites in mapping and discriminating between salt-affected soils in Kings County, California

Creator:: Gutierrez, Carmelita
Abstract:: Spectral profiles, transformed divergence values, and feature space derived from Landsat Thematic Mapper (TM) data were used to analyze the ability of four false color composites to discriminate between different classes of salt-affected soils. To compare the spatial distribution of salt-affected soil classes, maps were generated for each false color...

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 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....

Determination of Coastal changes in Lincoln County, Oregon using aerial photographic interpretation

Creator:: Smith, Elaine C.
Abstract:: In order for proper land use planning to occur in coastal Lincoln County, Oregon, coastal erosion rates should be determined. This has been accomplished by identifying the location of the Lincoln County coast in 1939, 1959, and 1973 and measuring the amount of change occurring between the years. The area...
