Uncertainty in forest road hydrologic modeling and catchment scale assessment offorest road sediment yield

Creator:: Surfleet, Christopher G.
Abstract:: The goal of this study was to advance methods for assessment of forest road hydrologic response and sediment yield at a catchment scale. This research looked at the effect of soil depth estimation on the Distributive Hydrology Soil Vegetation Model (DHSVM), assessed the uncertainty and accuracy of hydrologic modeling of...

The geology of part of the Snake River Canyon and adjacent areas in Northeastern Oregon and Western Idaho

Creator:: Vallier, Tracy L. (Tracy Lowell), 1936-
Abstract:: The mapped area lies between the Wallowa Mountains of northeastern Oregon and the Seven Devils Mountains of western Idaho. Part of the Snake River canyon is included. A composite stratigraphic section includes at least 30,000 feet of strata. Pre- Tertiary and Tertiary strata are separated by a profound unconformity. Pre...

Stratigraphy, sedimentology, and petrology of neogene rocks in the Deschutes basin, central Oregon : a record of continental-margin volcanism and its influence on fluvial sedimentation in an arc-adjacent basin

Creator:: Smith, Gary Allen
Abstract:: Neogene rocks of the Deschutes basin include the middle Miocene Columbia River Basalt Group and Simtustus Formation, and late Miocene to early Pliocene Deschutes Formation. Assignment of Prineville chemical-type flows to the Grande Ronde Basalt of the Columbia River Basalt Group is based upon correlation of these lavas from their...

Stratigraphy, sedimentology, and hydrocarbon potential of Eocene forearc and subduction zone strata in the southern Tyee Basin, Oregon Coast Range

Creator:: Ryu, In-Chang
Abstract:: Sequence stratigraphic analysis of the southern Tyee basin, Oregon Coast Range, reveals that the lower to middle Eocene forearc and subduction zone strata comprise four depositional sequences. Sequence I (lower Umpqua Group) represents a partially subducted accretionary wedge. Sequence II (upper Umpqua Group) is a deltaic sequence that filled irregular...

Sediments of Yaquina Bay, Oregon

Creator:: Kulm, LaVerne D., 1936-
Abstract:: Three realms of deposition, Marine, Fluviatile, and Marine- Fluviatile, are recognized in Yaquina Bay, Oregon, on the basis of sediment texture and mineralogy. The Marine Realm extends 1.5 miles into the entrance of the estuary and is typified by normal marine salinity and vigorous tidal action. Sediments of this realm...

Sedimentary petrology of some tertiary formations, Upper Nehalem River Basin, Oregon

Creator:: Van Atta, Robert O.
Abstract:: The southern half of the upper Nehalem River basin contains the most complete section of lower to middle Tertiary marine sedimentary and volcanic rocks in northern Oregon. Determination of stratigraphic relationships of six formations, and their depositional environments and provenance is the chief objective of this paper. More than 75...

Paleoenvironmental reconstruction of an active margin coast from the Pleistocene to the present : examples from southwestern Oregon

Creator:: Punke, Michele Leigh
Abstract:: This study illustrates geoarchaeological and paleoenvironmental approaches to the investigation of an active margin coastal setting and provides examples of how information gleaned through examination of the stratigraphic record can reveal depositional signatures that provide insights into the geomorphic and tectonic forces active within coastal river basins. Three case studies...
