Controls on movement of selected landslides in the Coast Range and western Cascades, Oregon

Creator:: Wong, Bernard Bong-Lap
Abstract:: The movement characteristics of five landslides are compared and interpreted based on records of approximately 10-years duration. Condon landslide in the Oregon Coast Range has consistently exhibited brief (1 - 8 days) movement episodes in wet winter months, separated by long periods of no movement. The translatory movement is probably...

Landslide occurrence in the Elk and Sixes River basins, southwest Oregon

Creator:: McHugh, Margaret H.
Abstract:: Timber management of coastal watersheds in southwest Oregon has been complicated by the need to protect anadromous fish habitat from accelerated stream sedimentation resulting from management activity. The rugged terrain of the Elk and Sixes River basins is underlain by the complex geological province of the Klamath Mountains, in which...

Mechanics and movement of the Lookout Creek Earthflow

Creator:: Mills, Keith A.
Abstract:: The Lookout Creek Earthflow is located in the Cascade Mountain Range in western Oregon. The Cascade Mountains are mainly volcanic in origin, and deposits in and around the slide have a complex geomorphic history,, affected by glacial, mass movement, and fluvial processes. The currently moving land mass is about 1600...

Landslide occurrence in the Blue River Drainage, Oregon

Creator:: Marion, Daniel A.
Abstract:: Rapid, shallow soil mass movements (landslides) are examined for a 6,000 ha managed forest area in the Oregon Western Cascades. Analysis of landslide occurrence considers the physical characteristics and frequency, the influence of clearcutting and road construction, and some resource impacts. Nonparametric statistical methods are employed to test the significance...

Discriminating between landslide sites and potentially unstable terrain using topographic indices

Creator:: Appt, Jeremy
Abstract:: A landslide inventory, statistical analyses and a Geographic Information System (GIS) are used to analyze landslide sites and potentially unstable terrain in the Oregon Coast Range. The objectives are to evaluate the efficacy of locating landslide sites with topographic variables and discriminate the difference between sites where landslides have and...

The delineation of landslides in the Lincoln County, Oregon Coastal Zone

Creator:: Gentile, John Richard
Abstract:: A study conducted along the Lincoln County, Oregon coast delineated the exact location of 153 landslides. The landslides were found through the interpretation of aerial photographs. Each landslide was verified in the field and its class (ancient, historic, recent), type (slump, debris slide or flow, planar slide),, and status (stable,...

Morphometric analysis of landslides and slope stability on the north shore of the John Day Reservoir, Columbia River, Oregon and Washington

Creator:: Woelke, Franziska
Abstract:: The John Day Reservoir, a large reservoir between the John Day and the McNary Dams on the Columbia River, must be lowered several feet below design level during salmon migration season in order to preserve anadromous fish habitat. This research assessed the north shore of the John Day Reservoir for...

Probabilistic analysis and mapping of seismically induced landslide deformation in Oregon

Creator:: Sharifi Mood, Mahyar
Abstract:: Landslides are ubiquitous within the state of Oregon, imposing an annual estimated cost of more than $10 million. Weak, saturated soils at steep slopes combined with persistent rainfall throughout most of the year provide a dangerous environment for this natural disaster, particularly in western Oregon. This grim situation is intensified...
