Creator:: Ricks, Cynthia L.
Abstract:: Since the early 1950's, the distribution of sediment at the mouth of Redwood Creek has been altered by the effects of channel aggradation and channelization along the lower reach. Severe flooding in 1953, 1955, and 1964 caused bank erosion, landsliding, and channel geometry changes along Redwood Creek. The increased sediment...

Creator:: Vest, Sarah B.
Abstract:: Slow moving earthflows (0.1 15 m/yr.) may constrict valley floors and directly impinge on stream channels. Earthflows that move laterally into channels deliver organic and inorganic material to the stream from the earthflow toe. If the amount and particle size of this material is too large to be removed by...

Creator:: Smith, Richard D. (Richard Dean), 1950-
Abstract:: A descriptive model of the routing of sediment that was delivered to the study area by the 1980 eruptions of Mount St. Helens has been developed. On hillslopes this sediment was distributed among three major storage compartments: 1) the tephra profile, 2) primary storage, and 3) secondary storage. The most...

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...

Creator:: Lane, Jeffrey W.
Abstract:: Various types of mass movement features are found in the drainage basin of the East Fork Coquille River in the southern Oregon Coast Range. The distribution and forms of mass movement features in the area are related to geologic factors and the resultant topography. The Jurassic Otter Point Formation, a...

Creator:: Hicks, Bryan A.
Abstract:: Landforms sculpted by mass movements comprise much of the landscape in the Middle Santiam study area. Bedrock in the area is mostly basalt and andesite flows and varied volcaniclastic rocks of the Little Butte Volcanic Series of Oligocene and early Miocene age, unconforniably overlain by andesite flows and tuffs of...

Creator:: Macario, Ana L. G.
Abstract:: The overall objective of this study is to address questions concerning the long-term mechanical strength of the lithosphere across the equatorial margin of Brazil. The approach used in this study consists of calculating the frequency response function estimates, also called admittance, using gravity and bathymetry data. These experimental estimates are...
