Prediction of monthly streamflows for Oregon coastal basins using physiographic and meteorological parameters

Creator:: Orwig, Charles Edwin
Abstract:: 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...

Determining the relationship between measured residence time distributions in lateral surface transient storage zones in streams and corresponding physical characteristics

Creator:: Coleman, Anthony M.
Abstract:: Surface transient storage (STS) in stream ecosystems serve an important function in retaining nutrients and refugia for aquatic communities. Unfortunately, they can retain contaminants as well. Therefore, it is of importance to determine the residence time distribution (RTD). A RTD of a particular STS zone encompasses the time it takes...

Analysis of streamflow variability in Oregon for regional water quality monitoring programs

Creator:: Saligoe-Simmel, Julia L.
Abstract:: Streamflow variability can provide valuable information for nonpoint source pollution monitoring program planning. The research papers presented in this thesis examine selected properties of streamflow variability in Oregon to advance its application in regional planning of water quality monitoring programs. The products of this research depict Oregon streams by their...

Estimating water flow rates

Creator:: Trimmer, Walter L. and Oregon State University. Extension Service
Abstract:: Measuring the flow rate of water is the first step to good water management. All water right holders in the State of Oregon must be able to measure the flow rate of the water being diverted.

Peak flow prediction for small forested watersheds along the southern Oregon and Northern California coast

Creator:: Andrus, Charles W., Froehlich, Henry A., and Pyles, M. R.
Resource Type:: Technical Report

Summer low flow characteristics of forest streams in northeast Oregon

Creator:: Widner, Gregory L.
Abstract:: Summer low flow characteristics of six forest streams in Northeast Oregon were examined using long term streamflow records. Time series and trend analysis revealed highly significant (alpha=O.O1) increasing trends in summer low flow over the period of record on four of the selected streams, and significant (alpha=O.05) year-to-year dependence on...

Characteristics of stream low flows in eastern Oregon : their relationship with precipitation and watershed parameters

Creator:: Zeb, Aurang
Abstract:: Characteristics of low flows of nine streams in eastern Oregon were explored using long-term streamflow records. Year-to-year dependence of low flows is highly significant for streams in the Blue Mountain and the southeastern Oregon regions. Low streamflows increased over the period of record for seven of the selected streams. Flow...

Reach scale sampling metrics and longitudinal pattern adjustments of small streams

Creator:: Robison, E. George
Abstract:: Several types of channel morphology measurement parameters used to characterize fish habitat of small streams are refined, developed and evaluated in terms of their accuracy, precision, and sensitivity to disturbance. Data for 74 stream reaches in Oregon and Alaska are used in analysis. Over half the reaches are from a...

Forest harvesting impacts on coarse woody debris and channel form in central Oregon streams

Creator:: Knight, Stephen M.
Abstract:: Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

Estimating streamflow characteristics for micro-hydro sites in northwestern Oregon

Creator:: Lieuwen, Andrew L.
Abstract:: 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...
