Analytical determination of copper speciation in Oregon highway runoff

Creator:: Sprick, Matthew S.
Abstract:: Low concentrations of dissolved copper have been shown to adversely affect the olfactory system of endangered salmonids, impairing their ability to avoid predators and likely increasing predation. It is believed that only the free ionic (Cu2+ free) and weakly complexed forms are bioavailable to organisms; these forms typically account for...

Changes in storm hydrographs due to clear-cut logging of coastal watersheds

Creator:: Harper, Warren Charles
Abstract:: The purpose of this study was to determine the effect of clearcut logging on stormflow by analysis of characteristic parameters of individual storm hydrographs. Parameters considered included height-of-rise, peak discharge, volume and time-to-peak. The hydrologic data were derived from experimental watersheds of the Alsea Study located in the Oregon Coast...

Storm runoff response from roadbuilding and logging on small watersheds in the Oregon Coast Range

Creator:: Hsieh, Frederic Shu-kong
Abstract:: The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed,...

Salinity, runoff and wind measurements, Yaquina Estuary, Oregon, April 1967-October 1968

Creator:: Callaway, Richard J., Ditsworth, George R., and Cutchin, D. L.
Abstract:: Conductivity data from which salinity values were computed were collected at 10 locations in Yaquina Bay from April 1967 to October 1968. Streamflow was measured for the Yaquina River, Elk Creek and Mill Creek from April 1967 to November 1968. Wind speed and direction data were collected near the mouth...

Statistical analysis and speciation modeling of copper in Oregon highway runoff

Creator:: Bloomquist, Don J.
Abstract:: Low levels of copper have been shown to impair the olfactory system of threatened and endangered (T&E) salmon, decreasing their predator avoidance behavior and likely increasing mortality. However, only dissolved copper (dissCu) present as the cupric ion (Cu2+) and weakly complexed species are truly bioavailable. Previous studies indicate the vast...

Sub-regional detention siting : a methodology using GIS

Creator:: Murdock, Carol L.
Abstract:: The Mt. Scott watershed in northern Clackamas County, Oregon is an urban watershed that lies inside the Portland metropolitan urban growth boundary. Urbanization of the watershed began in the early 1970s and has recently accelerated. A landscape level analysis of the urbanization process was combined with the results of a...

After the rain: urban runoff

Creator:: Oregon State University. Extension Service and Dodrill, Steve.
Abstract:: This program explains that urban water pollution comes from a number of common sources, such as automobiles, lawn and garden fertilizer, and pet waste, and explores ways in which citizens can minimize their contribution to such pollution.

Simulation of storm runoff in the Oregon Coast Range

Creator:: Fedora, Mark A.
Abstract:: Simulation of storm hydrographs in the Oregon Coast Range was explored using the Soil Conservation Service (SCS) curve number methodology, and by developing and testing an antecedent precipitation index (API) method. Standard SCS procedures over-estimated peak discharge by about a factor of two (i.e., average over-prediction of 118 percent). When...

We all live downstream

Creator:: Oregon State University. Extension Service, Dodrill, Steve, and Ragozzino, Ed
Abstract:: Examines the problems of runoff and nonpoint source pollution in Oregon's Tualatin River and how local residents and government officials are trying to reduce nonpoint source pollution. It also offers tips to help each of us play an active role in cleaning up our nation's drinking water supplies.

Water residence time and runoff generation in the western Cascades of Oregon

Creator:: McGuire, Kevin J.
Abstract:: The age, or residence time of water is a fundamental descriptor of catchment hydrology, revealing information about the storage, flow pathways and source of water in a single integrated measure. While there has been tremendous recent interest in residence time to characterize catchments, there are few studies that quantify residence...
