The effect of jet flow pulsing and blowing ratio on a jet in cross flow has been investigated. Preliminary jet flow studies were performed without cross flow and an extensive study of jet with cross flow was done for a total of nine test cases. The effect of velocities ratios...
In small forested streams, changes in age and structure of riparian vegetation covering the stream have been shown to directly influence the amount of light reaching the stream benthos. Light has the potential to impact in-stream resources that support secondary production through constraints on primary productivity. The influence of landscape...
This study examined features of deep pool (>0.8 m mean depth) used by
adult summer steelhead in Steamboat Creek (1991-1992). Steamboat Creek had
a heterogenous thermal profile, with some segments exceeding preferred
temperature of steelhead. Deep pools were scarce (4% of the total habitat units)
and 39% of them were...
Dredged spoil plumes are monitored during nine hopper dredge
disposal events in 186 foot water depths offshore near Coos Bay,
Oregon. Position and solids volume concentration characteristics of
the plumes are established.
Computer simulations of the monitored events are executed using
the WES modified version of the Koh-Chang instantaneous disposal...
Rainfall interception is a primary control over the moisture input to a forested ecosystem through the partitioning of precipitation into throughfall, stemflow, and an evaporated component (i.e. the interception loss). Rainfall interception is a spatially and temporally varying process at multiple scales, but heterogeneity in interception processes are poorly understood...
An analytical solution is developed for the temperature
profile of a unit cell consisting of a sphere of one
material centered in a cube of a second material. All
material properties are considered constant and boundary
conditions consist of specified temperatures on the top
and bottom faces of the cube...
In this study the ability of establishing time standards using the
technique of regression analysis is demonstrated. Numerical standards
are developed for fish filleting operations which are satisfactory for
practical use by the seafood processing management.
For the analysis non-experimental or historical fillet data was
obtained from two seafood processors...
Chloride ion migration was studied under accelerated cathodic protection conditions using 6" x 6" x 6" mortar blocks of varying initial chloride content and water to cement ratios. An iron mesh embedded parallel to one face in the blocks acted as the cathode and zinc was thermally sprayed on the...
