The behavior of a stream upon entering a field reservoir was
studied at various stages of stratification. The principal field techniques
included fluorometric and temperature surveys. General
relationships were obtained, between dimensional and locational characteristics
of the inflow current and the thermal structure of the
impoundment. As predicted by analytical...

This study is part of the Alsea Basin Logging-Aquatic Resources
Study research program. It was initiated to determine the applicability
of energy budget theory to stream temperature prediction on small
forested streams. The study was also designed to evaluate the energy
budget technique as a tool in the management of...
Prediction equations were developed for estimating the flow
regime at ungaged stream locations in the Oregon coastal range.
Principal components analysis was used to screen the initial data set
of physiographic and meteorological parameters. The final regression
equations for predicting mean monthly flow had standard errors of
estimate ranging from...
Statistical summaries of streamfiow data at 358 stream-gaging sites
are presented to aid in appraising the hydrology of river basins in Oregon.
Records for 36 stream-gaging stations were compiled into separate periods
because of changes in streamflow regulation during the period of data
collection. Statistical summaries for the periods before...
This study data from the Alsea Watershed Study located
approximately ten miles from the Pacific Ocean in the Oregon Coast
Range. The purpose was to evaluate the effects of roadbuilding on
storm flows in two experimental streams. One 138 acre watershed,
Deer Creek II, was subjected to 3.5 percent treatment...
A methodology for estimating streamf low characteristics on Ungaged
streams was developed for northwestern Oregon. Basin area and
basin area multiplied by the square root of relief were found to be
effective independent variables in regression models for estimating
the average annual flow, the average daily flood with a two-year...
The mechanisms of pool maintenance were investigated in a small (width = 10 m,
drainage area = 18 km2), gravel-bed stream where pools are commonly associated with
large, in-channel obstructions. Measurements of boundary shear stress, scour and fill of
the stream bed, and bedload transport rate and grain-size distribution were...
