Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

Creator:: La Nier, Justin
Abstract:: Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

Sustainable construction safety and health rating system

Creator:: Rajendran, Sathyanarayanan
Abstract:: The main objective of this research study is to incorporate construction worker safety and health into sustainable design and construction practices. This can be fulfilled by the development of an innovative construction worker safety and health planning tool, called Sustainable Construction Safety and Health (SCSH) Rating System that will: •...

Strain distribution in OSB and GWB in wood frame shear walls

Creator:: Sinha, Arijit
Abstract:: The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...

Uranium and technetium bio-immobilization in intermediate-scale physical models of an in situ bio-barrier

Creator:: Michalsen, Mandy M.
Abstract:: Metal and hydrogen ion acidity and extreme nitrate concentrations typical of Department of Energy (DOE) legacy waste sites pose formidable challenges to successful implementation of in situ bio-immobilization. Intermediate-scale (~ 2.5 m), flow through models of an in situ bio-barrier were constructed to investigate U and Tc removal from groundwater...

Testing and evaluation of flexural reinforcing bars terminating in columns

Creator:: Koester, Carl C.
Abstract:: Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

Location of the neutral axis in wood beams

Creator:: Holm, Sarah C.
Abstract:: It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...

Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

Quantification of advection and dispersion in lateral subsurface flowpaths at the hillslope-scale

Creator:: Victory, Nichole I.
Abstract:: It is becoming increasingly important to understand fundamental hillslope-scale hydrological processes. Most hillslope-sale transport experiments have generally focused on conceptual findings or other aspect of flow behavior, rather than the quantification of the mass transport mechanisms of advection and dispersion. When the velocities have been quantified, dispersion has been mentioned...

Tidal influence on downstream fining in gravel-bed rivers

Creator:: Coles, Derron Rafiq
Abstract:: This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

Reducing sediment production from forest roads during wet-weather use

Creator:: Toman, Elizabeth Myers
Abstract:: Forest roads produce fine sediment with traffic during wet weather. If the forest road is connected to a stream it can be a source of turbidity and fine sediment that may be detrimental to aquatic organisms especially salmonids. The goal of this work was to investigate turbid runoff during wet-weather...
