Late winter 1992 sampling for water quality in three stream segments of the Tualatin River Basin, Oregon

Creator:: Miner, J. Ronald, Nelson, Peter O., Vedanayagam, Samuel, Oregon State University. Water Resources Research Institute, and Oregon State University. Extension Service
Abstract:: The Tualatin River Basin in Washington County, Oregon has been identified by the Oregon Department of Environmental Quality (DEQ) as "Water Quality Limited." Algal blooms have become commonplace in the lower , reaches of. the river during summer months. Phosphorus has been identified as the nutrient upon which to base...

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...

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...
