Input/output energy analysis of regional water pollution control

Creator:: Heggen, Richard J.
Abstract:: Two strategic approaches to water quality control in Oregon's Willamette River are presently being utilized: point source treatment and flow augmentation. Dry weather releases from reservoirs are for authorized purposes other than water quality. Reservoirs can participate in pollution control by summer flow augmentation where authorized water resource objectives (flood...

An investigation of alternative means of achieving water quality objectives

Creator:: Kerri, Kenneth Donald
Abstract:: Storage of water for water quality control is one of the alternative means of achieving water quality objectives. Authorities in the field of water quality management disagree regarding the use of precious water for the dilution of wastes. The costs of achieving water quality objectives by treatment of wastes at...

Summary and assessment of toxics data for the Tualatin River

Creator:: Khaodhiar, Sutha, Nelson, Peter O., and Oregon State University. Water Resources Research Institute
Abstract:: The Tualatin River is a major water resource for Washington County. In its course, the river drains forest lands, farmlands, and urban areas receiving toxic materials from non-point source runoff: Wastewater treatment plant effluents from municipalities and industries also contribute toxic materials to the river. Many materials discharged into the...

An evaluation of the oxygen resources in the lower Willamette River during a critical low flow period

Creator:: Kari, Earl Nyhus
Abstract:: The lower Willamette River, located between river mile 4.0 and 26.5, is the most seriously polluted section of the Willamette River Basin. Low dissolved oxygen concentrations of 2.0 to 3.0 mg/1 are observed annually in this section of the river due to the pollutional loads discharged into it. Waste discharges...

Modeling the Tualatin River system including Scoggins Creek and Hagg Lake: model description, geometry, and forcing data

Creator:: Wells, Scott A., Berger, Christopher, Knutson, Mike, and Oregon State University. Water Resources Research Institute
Abstract:: The goal of this phase of the study was to develop a model of the Tualatin River incorporating Scoggins Creek and Hagg Lake. This tool will be used in conjunction with a hydrologic model, the EPA HSPF model (Johnson, Imhoff, and Kittle, 1984), to analyze management strategies to improve water...

A system analysis method for water quality management by flow augmentation

Creator:: Worley, John Larry
Abstract:: A rapid expansion of population and industrialization in recent years has created new and difficult problems in water resources management. Prudent management of water quality will require that more efficient methods be developed for evaluating large volumes of data on complex river systems, and tabulating the results in a form...

An evaluation of planning for water quality control in the Willamette River Basin

Creator:: Kirkpatrick, Kenton
Abstract:: It is no longer possible in any area of the United States to formulate water resources plans for single purpose projects as has been done in past years. No longer can one of our greatest natural resources, water, be used solely for navigation, power generation, irrigation, or controlled for reducing...

Mass balance analysis of suspended solids in the Tualatin River

Creator:: Vedanayagam, Samuel, Nelson, Peter O., and Oregon State University. Water Resources Research Institute
Abstract:: The purpose of this study was to develop a mass-balance model for total suspended solids in the Tualatin River in order to better understand the clarity-turbidity problem in the river. Major sources and sinks of suspended solids in the river were identified, and seasonal effects were explored. The study also...
