Nays2D Modelling results for three reaches in the Oregon Coast Range before and after the addition of Large Wood

Creator:: Segura, Catalina and Bair, Russell
Abstract:: This data set includes the calibrated predictions of Depth, Elevation, Water Surface Elevation, Shear Stress, Vorticity, and Froude Number for three reaches in the Mill Creek watershed, a tributary of the Siletz River, Oregon. The predictions are for bankfull flow before and after the addition of Large Wood using Nays2DH,...

Influence of vegetation on streambank hydraulics

Creator:: Czarnomski, Nicole M.
Abstract:: Proper use of vegetation in streambank bioengineering practices requires a comprehensive understanding of the influence of vegetation density on streambank hydraulics. A series of studies were conducted to investigate the relationship between independent variables vegetation density, bank angle, and discharge and dependent variables channel velocity, resistance, turbulence, and shear stress....

Simulation of storm runoff in the Oregon Coast Range

Creator:: Fedora, Mark A.
Abstract:: Simulation of storm hydrographs in the Oregon Coast Range was explored using the Soil Conservation Service (SCS) curve number methodology, and by developing and testing an antecedent precipitation index (API) method. Standard SCS procedures over-estimated peak discharge by about a factor of two (i.e., average over-prediction of 118 percent). When...

Modeling the hydrological aspects of the Fern Lake Watershed : annual report 1971

Creator:: Fowler, Charles W. (Charles Winsor), 1941-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Data collected from the Fern Lake watershed between 1958 and 1971 include measurements of the rate of flow of water into the lake through a single inlet stream. The objective of the work presented here is to develop a model of this flow using the climatological data available from the...

On the estimation and application of spatial and temporal autocorrelation in headwater streams

Creator:: Som, Nicholas A.
Abstract:: This collection of three manuscripts serves to improve methods for collecting, interpreting, and utilizing autocorrelated data from headwater stream networks. Each stream network is comprised of linear segments. These segments lie within a unique branching structure that connects the segments via flowing water, and the connectivity provided by water varies...

Watershed response to western juniper control

Creator:: Deboodt, Timothy L.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a...

Modeling surface water and groundwater interactions near Milton-Freewater, Oregon

Creator:: Petrides Jimenez, Aristides Crisostomos
Abstract:: The gravel aquifer of the Oregon side of Walla Walla River Basin has a strong hydrologic connection to surface water through a series of springs, unlined irrigation canals, the Walla Walla River, numerous wells and, since 2004, artificial recharge to the shallow aquifer using infiltration basins. The finite element Integrated...

Sediment reservoir dynamics on steepland valley floors : influence of network structure and effects of inherited ages

Creator:: Frueh, Walter Terry
Abstract:: Sediment deposit ages inferred from radiocarbon dating of stream bank material were used to estimate residence times of valley-floor deposits in headwater valleys of the Oregon Coast Range, USA. Inherited ages of radiocarbon-dated material, i.e., time between carbon fixation in wood and its incorporation in a sediment deposit, can result...

Hydro-biogeochemical coupling at the hillslope and catchment scale

Creator:: van Verseveld, Willem J.
Abstract:: The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls on DOC and N transport at the hillslope and catchment scale. The study area is a small catchment where hillslopes issue directly...
