A helically flighted rotating tube for concentrating dairy and
swine manure solids was developed and evaluated. The solids removal
and concentration factor values were measured with beet pulp,
dairy manure arid swine manure slurries at different influent flow
rates and suspended solids concentrations. A method of estimating
the performance of...
The one-dimensional numerical model developed by Carl R.
Goodwin is applied to the Siuslaw estuary. Vertical displacement,
horizontal velocity and flow of the water as a function of time and
distance from the mouth given by the model are compared with field
observations taken under different water mixing conditions in...
Recent concern over the potential environmental impact of highway construction
and repair materials on surface and ground waters has lead to extensive laboratory
screening and subsequent testing of a set of new materials and waste amended mixes. As
part of Phase II of a three-phase project for the National Cooperative...
A spreadsheet-based transport model was developed in Microsoft Excel™ as part of a six-year National Cooperative Highway Research Program project conducted at Oregon State University. The model simulated the leaching, transport, removal, and retardation processes that occur in the surface and subsurface pathways of the near highway environment. For all...
Two land breeze events occurred off the Oregon coast on the
nights of April 19th and 20th, 1973. An array of four moored toroid
buoys and one land station recorded the effect of the land breeze event
on the surface mesoscale wind and temperature fields. The land
breezes may have...
