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...

Geographical geomorphology : historical development, contemporary problems, and future prospects

Creator:: Beach, Gary L.
Abstract:: Geographical geomorphology is a young science with a long, complex history closely paralleling the growth and development of geology. From an enthusiastic beginning under the tutelage of William Morris Davis, geographical geomorphology rapidly lost its influence and stature in geography. Today there is a sense of purpose and direction that...

A hydrological study of the Coast Fork/Middle Fork Willamette River Confluence Area

Creator:: Rogers, Valerie M.
Abstract:: The main purpose of this project is to describe the hydrologic characteristics, with and without regulation by dams, of the Coast and Middle Forks of the Willamette River, including the floodplain, from the confluence to approximately eight miles upstream. The research is intended to assess the future potential of the...

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...

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...

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...

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,...

Sediment accumulation within weathering pits on Dance Hall Rock, Grand Staircase-Escalante National Monument, Utah

Creator:: Taddie, Marissa C.
Abstract:: The purpose of this paper was to examine if the depth and degree of circularity of weathering pits affects the accumulation of sediment. Thirty pits were surveyed over two one-week periods on Dance Hall Rock. Weathering pits were measured to determine their maximum width, minimum width, vertical depth, and depth...

Developing a Geographic Information System county template to support tsunami evacuation route planning on the Oregon Coast

Creator:: Gomez, Kyle R.
Abstract:: Tsunamis pose a major threat to Oregon's coastal communities. Evacuation is the best method to mitigate for tsunamis. Planning for tsunami evacuation is underway in Oregon's coastal communities. Current methodologies use tsunami inundation models and population for evacuation planning. Tsunamis from a Cascadia subduction zone (CSZ) earthquake will create more...

Storm-induced mass wasting in forested areas: conditions and characteristics for three Western Oregon study sites

Creator:: Robben, Joshua L.
Abstract:: Much of the rich forestlands of Oregon are subject to frequent mass wasting events, resulting in severe environmental and economic damages. Extensive research has shown that this landslide hazard is often exacerbated by many management activities. Following a severe storm event which triggered thousands of landslides, the Oregon Department of...
