Longshore grain sorting and beach-placer formation adjacent to the Columbia River

Creator:: Li, Zhenlin
Abstract:: The formation of beach placers primarily involves processes of waves and currents that selectively sort and concentrate the valuable minerals according to their densities, sizes and shapes. Black sand placers are found on the beaches adjacent to the mouth of the Columbia River. Reviews of historical shoreline changes show that...

Processes of sea-cliff erosion on the Oregon coast : from neotectonics to wave run-up

Creator:: Shih, Shyuer-ming
Abstract:: Sea-cliff erosion is a significant problem along the Oregon coast in that many communities have been built on terraces affected by bluff retreat. There is considerable coast-wide variability in the rates of cliff erosion. This variability is attributed in part to tectonic activity that is causing differential interseismic uplift along...

Robert Hooke and the foundation of geology : a comparison of Steno and Hooke and the Hooke imprint on the Huttonian theory ; and, The tectonic evolution of the Oregon continental margin : rotation of segment boundaries and possible spacetime relationships in the Central High Cascades

Creator:: Drake, Ellen T.
Abstract:: Based on the principle that the history of a discipline is important to the discipline itself, this thesis devotes two chapters to ROBERT HOOKE AND THE FOUNDATION OF GEOLOGY and two chapters to modern geology, viz. THE TECTONIC EVOLUTION OF THE OREGON CONTINENTAL MARGIN. The first part of this abstract...

Streamflow and bedload transport in an obstruction-affected, gravel-bed stream

Creator:: Smith, Richard D. (Richard Dean), 1950-
Abstract:: The mechanisms of pool maintenance were investigated in a small (width = 10 m, drainage area = 18 km2), gravel-bed stream where pools are commonly associated with large, in-channel obstructions. Measurements of boundary shear stress, scour and fill of the stream bed, and bedload transport rate and grain-size distribution were...

Experimental evaluation and chemical modeling of hexavalent chromium adsorption, desorption, and reduction in a natural soil

Creator:: Azizian, Mohammed F.
Abstract:: Chromium and its compounds are widely used by modern industries, resulting in large quantities of this element being discharged into the environment. To remove chromium from contaminated soils and ground water, it is necessary to predict chemical and physical processes that control the rate of reactions and transport of chromium...

Chemical control of Elodea densa Planch. and other submersed aquatic plants as influenced by several environmental factors

Creator:: Mackenzie, John William, 1939-
Abstract:: Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1] heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate. Studies were conducted in coastal lakes of Oregon infested with E. densa. Dichlobenil (2, 6 dichlorobenzonitrile)...
