Water savings through surge irrigation, 1994

Creator:: Shock, Clinton C., English, M. J., Mittelstadt, R. W., Shock, Byron M., Oregon State University. Malheur Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: Stephens winter wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously four times during the season. Conventional irrigation applied 26.5 ac-in/ac of water with runoff of 0.8 ac-in/ac and infiltration of 25.7 ac-in/ac. Surge irrigation applied 13.7 ac-in/ac with 0.5...

Surge irrigation of wheat, to increase irrigation efficiency and reduce sediment loss, 1993

Creator:: Shock, Clinton C., Saunders, Lamont D., English, M. J., Mittelstadt, R. W., Shock, Byron M., Oregon State University. Malheur Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: Treasure spring wheat was grown using conventional furrow irrigation and surge irrigation on 12 one-half-acre plots. Both systems were operated simultaneously five times during the season. Conventional irrigation applied 24.7 ac-in of water with runoff of 5.6 ac-in and infiltration of 19.1 ac-in. Surge irrigation applied 12.0 ac-in with 1.7...

Improved irrigation efficiency and reduction in sediment loss by mechanical furrow mulching wheat

Creator:: Shock, Clinton C., Saunders, Lamont D., Shock, Byron M., Hobson, Joe H., English, M. J., Mittelstadt, R. W., Oregon State University. Malheur Experiment Station, and Oregon State University. Agricultural Experiment Station
Abstract:: Treasure spring wheat was grown on sloping ground with and without mechanically applied furrow mulching. Furrow mulching used 800 lb/ac of wheat straw. Mulched and non-mulched furrows were irrigated five times during the season receiving 483 and 19.0 and 40.9 ac-in of irrigation water, respectively. For non-mulched furrows, infiltration totaled...

Data analysis: water quality of Dairy Creek and major tributaries

Creator:: Oregon State University. Water Resources Research Institute, Miner, J. Ronald, and Scott, Eric F.
Abstract:: Dairy Creek, located in Washington County, Oregon, has a drainage area of approximately 230 square miles, and includes West Fork, East Fork, and McKay Creek drainages. Dairy Creek is a major tributary of the Tualatin River which experiences algal problems during the late summer when stream flows decrease and water...

The historical Tualatin River Basin

Creator:: Cass, Penny L., Miner, J. Ronald, and Oregon State University. Water Resources Research Institute
Abstract:: Dionysius said that history is philosophy learned from examples. As one of the original four counties of the Territory of Oregon, the Tualatin River Basin is rich in history. While still a prime agricultural region, the Tualatin Valley is one of the state's fastest developing areas. The slow accumulation of...

Agricultural land use in the Tualatin Basin

Creator:: Scott, Eric F., Wood, Mary, Warkentin, Benno P., and Oregon State University. Water Resources Research Institute
Abstract:: This report presents estimates of land uses, concentrating on agricultural land in the Tualatin drainage basin. Acreage in different crop groups and agricultural water use and distribution in the watershed were estimated. The total amounts of nitrogen and phosphate applied to agricultural land and the average loading of nutrients per...

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...

An analysis of water quality data in Tualatin River tributaries with three different land uses

Creator:: Miner, J. Ronald, Scott, Eric F., and Oregon State University. Water Resources Research Institute
Abstract:: Water quality and stream flow data for tliree representative land uses in the Tualatin River Basin were evaluated to determine the comparative levels of various pollutants. In addition, the data were used in an effort to identify the extent to which observed concentrations of total and ortho phosphorus could be...

Estimating the frequency and quantity of surface runoff within the Tualatin River Basin

Creator:: Taylor, George H., Klingeman, Peter C., Miner, J. Ronald, and Oregon State University. Water Resources Research Institute
Abstract:: The Tualatin River Basin along the east side of the Coastal Mountains in Oregon is subject to a complex mixture of land uses. Approximately half the area is devoted to forestry production. The remainder is divided between agriculture and urban uses. In addition to this diversity in land use, there...
