Cast-in-Place 2-Foot Concrete Trapezoidal Flow-Measuring Flumes NWISRL
Humpherys, A.S.; Bondurant, J.A..
Procedures are presented for casting 50-ft^2/sec trapezoidal water measurement flumes in 2-foot bottom width lined and unlined ditches. Drawings and construction details for the concrete forms used are also presented. Flumes installed in concrete-lined ditches require about 13 man-hours and cost about $230. Flow can be determined for both free and submerged flow conditions from rating tables with depth measured in a sitting well or with a sloping gage on the flue sidewall.

Comparison of fall and spring bedding for furrow irrigated potatoes following fall moldboard or chisel plowing NWISRL
Shock, C.; Stieber, T.; Eldredge, E.; Sojka, R.; Kennedy-Ketcheson, E..
The decision to fall or spring bed potatoes is often dictated by weather and processor contract agreements. Although there are advantages to both fall an( spring bedding, soil conditions are often wet in the spring in Malheur County, Oregon. Spring bedding of wet soils leads to soil compaction and decreased water infiltration. The primary objective of the study was to determine the effects of fall or spring bedding on tuber yields and quality under furrow irrigation. Determining the most effective method of fall potato ground preparation was the second objective of the trial. Land for potato production is normally moldboard plowed in the fall. Chisel plowing may provide better placement of residues in bedded ground and thus promote higher...

Control of Sediments, Nutrients, and Adsorbed Biocides in Surface Irrigation Return Flows NWISRL
Carter, David L.; Bondurant, James A..
The technology available for the control of sediments, nutrients, and adsorbed biocides in surface irrigation return flows has been reviewed and evaluated. Some of this technology could be applied immediately to reduce sediment and associated nutrient and biocide concentrations in surface irrigation return flows. Much of the available information needs to be integrated to develop improved control practices. New ideas and new control technology are needed. Economic incentive programs are needed to improve acceptance of control technology. The factors controlling erosion and subsequent sediment concentrations in surface irrigation return flows, and how these factors can be managed to reduce erosion and sediment concentrations are reviewed and...
