Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Creator:: Selker, J., Parlange, J.-Y., and Steenhuis, T.
Abstract:: An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provides applicable results, including the calculation of the asymptotic matric potential of a growing finger...

The Temporal Response of the Length of a Partially Stratified Estuary to Changes in River Flow and Tidal Amplitude

Creator:: Lerczak, James A., Geyer, W. Rockwell, and Ralston, David K.
Abstract:: The temporal response of the length of a partially mixed estuary to changes in freshwater discharge Q𝒻 and tidal amplitude Uₜ is studied using a 108-day time series collected along the length of the Hudson River estuary in the spring and summer of 2004 and a long-term (13.4 yr) record...

Turbulent mixing in a strongly forced salt wedge estuary

Creator:: Ralston, David K., Geyer, W. Rockwell, Lerczak, James A., and Scully, Malcolm
Abstract:: Turbulent mixing of salt is examined in a shallow salt wedge estuary with strong fluvial and tidal forcing. A numerical model of the Merrimack River estuary is used to quantify turbulent stress, shear production, and buoyancy flux. Little mixing occurs during flood tides despite strong velocities because bottom boundary layer...

Structure, variability, and salt flux in a strongly forced salt wedge estuary

Creator:: Ralston, David K., Geyer, W. Rockwell, and Lerczak, James A.
Abstract:: The tidally varying circulation, stratification, and salt flux mechanisms are investigated in a shallow salt wedge estuary where fluvial and tidal velocities are large and the steady baroclinic circulation is comparatively weak. The study integrates field observations and numerical simulations of the Merrimack River estuary. At moderate to high discharge...

Subtidal Salinity and Velocity in the Hudson River Estuary: Observations and Modeling

Creator:: Ralston, David K., Geyer, W. Rockwell, and Lerczak, James A.
Abstract:: A tidally and cross-sectionally averaged model based on the temporal evolution of the quasi-steady Hansen and Rattray equations is applied to simulate the salinity distribution and vertical exchange flow along the Hudson River estuary. The model achieves high skill at hindcasting salinity and residual velocity variation during a 110-day period...

Western wildcucumber, Marah oreganus (T. & G.) Howell

Creator:: Burrill, L. C., Oregon State University. Extension Service, Washington State University. Cooperative Extension, University of Idaho. Cooperative Extension System, United States. Department of Agriculture, and Pacific Northwest Cooperative Extension
Abstract:: Western wildcucumber (Marah oreganus [T. & G.] Howell), also known as Oldman- in-the-ground, Echinocystis oregana Cogn., is a perennial with stems that regrow each spring from a huge woody root. Stems become long, and they climb with the aid of branched tendrils. Leaves are alternate, lobed, and up to 6...

Comparing anuran performance and movement

Creator:: Bredeweg, Evan M.
Abstract:: Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...

Management of Pacific Rockfish

Creator:: Parker, S. J., Berkeley, S. A., Golden, J. T., Gunderson, D. R., Heifetz, J., Hixon, M. A., Larson, R., Leaman, B. M., Love, M. S., Musick, J. A., O'Connell, V. M., Ralston, S., Weeks, H. J., and Yoklavich, M. M.
Abstract:: The American Fisheries Society (AFS) recognizes the need for conservative and robust management of Pacific rockfishes because of naturally low population growth, the overfished state of many of the stocks, and complex nature of the mixed-stock fisheries (60-plus species). The AFS recommends that catch information be collected on a species-specific...

Continuous Flow Synthesis of Ceria Nanoparticles Using Static T-mixers

Creator:: Palanisamy, Barath and Paul, Brian
Abstract:: Ceria nanoparticles are of interest owing to their interesting properties like photo-absorption and ability to absorb oxygen. Several batch synthesis routes exist however these methods often lack particle size control, result in agglomeration and typically require high temperature processing. In this paper, a continuous flow microchannel synthesis method based on...
