Spatial and temporal runoff response to snowmelt, and the influence of geomorphology in a headwater catchment, central eastern Cascades, Washington

Creator:: Alley, David
Abstract:: This report presents a nested gauging study of streamflow variability from three sub-catchments (150-200 ha in area) of the Burns Creek catchment (565 ha) in the Entiat Experimental Forest of central Washington State. We test and reject the hypothesis that headwater catchments of this size are composed of physically and...

Hillslope hydrology : from patterns to processes

Creator:: Tromp-van Meerveld, Hilda J.
Abstract:: This dissertation re-examines the now standard perceptual model of hillslope hydrological response to rainfall, which includes the growth of a saturated wedge at the soil-bedrock interface or impeding layer. It also challenges the notion of bedrock impermeability and the assumption that the pattern of subsurface stormflow is determined by the...

Water residence time and runoff generation in the western Cascades of Oregon

Creator:: McGuire, Kevin J.
Abstract:: The age, or residence time of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways and source of water in a single integrated measure. While there has been tremendous recent interest in residence time to characterize catchments, there are few studies that quantify residence...

Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Establishment of Kura clover for seed with wheat intercrops

Creator:: Snelling, John P.
Abstract:: Kura clover (Trifolium ambiguum M. Bieb.) is slow to establish and has low seed yields the year after establishment. Intercropping a cereal grain during clover seed field establishment could provide additional revenue to seed growers, provided that intercropping did not jeopardize future clover seed yields. Factorial combinations of spring- and...

Water management effects on birdsfoot trefoil seed production

Creator:: García-Díaz, Carlos Alberto
Abstract:: There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...

Contractile function of single muscle fibers from chronically resistance trained humans

Creator:: Shoepe, Todd C.
Abstract:: Resistance training is widely prescribed for rehabilitation of injuries and as a method to improve athletic performance. It is accepted that resistance training increases the maximal force production of whole muscle and it has been suggested that the velocity of shortening can increase as well. However, little is known about...

Effect of nutrients on interactions between two decay fungi and Trichoderma harzianum Rifai on ponderosa pine sapwood wafers

Creator:: Canessa, Edwin
Abstract:: Small size wood assays were utilized to study the effect of added nutrients to the wood on the interactions of Trichoderma harzianum Rifai and two wood decay fungi, Trametes versicolor (white rot) and Gloeophyllum trabeum (brown rot). Weight losses related to time of exposure were monitored as a measure of...
