Creator:: Impara, Peter C.
Abstract:: Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...

Creator:: Casebeer, Nathan E.
Abstract:: This study is part of the effort to quantify sediment budgets and understand the geomorphic evolution of steep mountains where debris flows are the dominant agent of upland erosion. Observations indicate that headwater basins in the Oregon Coast Range (OCR) can store a large amount of sediment, mostly from debris...

Creator:: Oxford, Jeremiah
Abstract:: The Early Oligocene Oregon Coast Range Intrusions (OCRI) consist of gabbroic rocks and lesser alkalic intrusive bodies that were emplaced in marine sedimentary units and volcanic sequences within a Tertiary Cascadia forearc basin. The alkalic intrusions include nepheline syenite, camptonite, and alkaline basalt. The gabbros occur as dikes and differentiated...

Creator:: Anderson, Paul Khalil
Abstract:: This study investigates patterns of physical structure organization in stream networks. In particular, it seeks to describe patterns of wood, boulders, pools and slope that are evident in stream channels and to determine whether patterns of these elements are influenced by network-level controls. The four in-stream parameters were combined to...

Creator:: VanLaningham, Sam J.
Abstract:: Analysis of topographic and river morphometric parameters was conducted using digital elevation models (DEMs) and field observations in order to determine the role of variable rock resistance on topographic relief, to examine how spatially and temporally variable rock uplift rates relate to river morphology, and to address the degree to...
