Spillway Staging and Selective Sediment Deposition in Sand Storage Dams

Creator:: Viducich, Jonathan M. G.
Abstract:: Rainfall scarcity and variability present serious challenges to water security for many rural communities throughout the world's drylands. Sand dams--weirs built across ephemeral or seasonal rivers--provide an appropriate water harvesting and storage option for many regions. The structures quickly fill with sediment during rainy season flow events and store water...

Sediment potentials for selected ecological land units in central Oregon

Creator:: Mattison, Jeffrey L.
Abstract:: During the summers of 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of Crook County, in central Oregon. The Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a...

Particle selection for tube building and the stabilization of sediments by Leptochelia dubia (Crustacea, Tanaidacea): interactions with bacteria and microalgae

Creator:: Krasnow, Lynne D.
Resource Type:: Dissertation

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...

Vitamin B₁₂ production and depletion in a naturally eutrophic lake

Creator:: Gillespie, P. A.
Abstract:: The vitamin B₁₂ concentrations in both the water and sediments of Klamath Lake were found to vary significantly during a one-year period. The patterns of B₁₂ distribution were remarkably similar among the three main sites. In all cases there was an extremely sharp gradation in concentration in relation to depth...

Along-coast variations of Oregon beach-sand compositions produced by the mixing of sediments from multiple sources under a transgressing sea

Creator:: Clemens, Karen E.
Abstract:: Heavy mineral compositions of sands from Oregon beaches, rivers and sea cliffs have been determined in order to examine the causes of marked along-coast variations in the beach-sand mineralogy. The study area extends southward from the Columbia River to the Coquille River in southern Oregon. The heavy-mineral compositions were determined...

Fine benthic organic matter (FBOM) dynamics in low-order mountain streams : (1) methods evaluation and (2) the effects of stand age, season, and elevation on FBOM nutrient availability and microbiological characteristics

Creator:: Bonin, Heather
Abstract:: Allochthonous litter inputs are a primary source of organic matter in low-order forested streams. A major component of this litter moves through small streams as fine particulate organic matter (FPOM). Litter decomposition has been well studied, but few studies have examined benthic FPOM (FBOM) dynamics. The purpose of this study...
